Crankshaft sensor location?

Good afternoon

There are two for this model. I have attached pictures and procedures for both.

Do you have a code for this repair?

Roy

This is the one on the back of the motor

REMOVAL PROCEDURE
1. Turn the steering wheel fully to the left.

CAUTION: Refer to Caution in Service Precautions.

2. Raise vehicle on hoist.
3. Disconnect sensor electrical connector.
4. Remove bolt/screw.
5. Remove sensor from engine.
6. Inspect for the following:
6.1. Inspect the sensor for wear, cracks, or leakage. Replace the O-ring if necessary.
6.2. Lubricate the new O-ring with clean engine oil before installing.

This is the one behind the crankshaft pulley in the front of the motor

REMOVAL PROCEDURE

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.

1. Disconnect the negative battery cable.
2. Remove the serpentine drive belt from crankshaft pulley.

CAUTION: Refer to Caution in Service Precautions.

3. Raise the vehicle on hoist.
4. Remove the crankshaft harmonic balancer retaining bolt.
5. Remove the crankshaft harmonic balancer.
6. Note the routing of sensor harness before removal.
7. Remove the harness retaining clip with bolt (1).
8. Remove the sensor electrical connector.
9. Remove the sensor bolts (2).
10. Remove the sensor.


if you replace the one behind the crank pulley, it has to have a relearn procedure done with a scan tool.

The crankshaft position system variation compensating values are stored in the PCM non-volatile memory after a learn procedure has been performed. If the actual crankshaft position system variation is not within the crankshaft position system variation compensating values stored in the PCM, DTC P0300 may set. Refer to Diagnostic Aid for DTC P0300.

The Crankshaft Position System Variation Learn Procedure should be performed if any of the following conditions are true:
^ DTC P1336 is set.
^ The PCM has been replaced.
^ The engine has been replaced.
^ The crankshaft has been replaced.
^ The crankshaft harmonic balancer has been replaced.
^ The crankshaft position sensor has been replaced.

IMPORTANT: The scan tool crankshaft position system variation learn function will be inhibited if engine coolant temperature is less than 70°C (158°F). Allow the engine to warm to at least 70°C (158°F) before attempting the crankshaft position system variation learn procedure.

The scan tool crankshaft position system variation learn function will be inhibited if any powertrain DTCs other than DTC P1336 are set before or during the crankshaft position system variation learn procedure. Diagnose and repair any DTCs if set.

The crankshaft position system variation learn function will be inhibited if the PCM detects a malfunction involving the camshaft position signal circuit, the 3X reference circuit, or the 24X reference circuit.
^ If the scan tool indicates a problem with the Cam signal, refer to DTC P0341 Camshaft Position (CMP) Sensor Performance.
^ If the scan tool indicates a problem with the 3X crank signal, refer to DTC P1374 3X Reference Circuit.
^ If the scan tool indicates a problem with the 24X crank signal, refer to DTC P0336 24X Reference Signal Circuit.
1. Depress and hold the service brake pedal.
2. Block the drive wheels.
3. Ensure the hood is closed.
4. Start the engine and allow engine coolant temperature to reach at least 70°C (158°F).
5. Turn OFF the ignition switch.
6. Select the crankshaft position variation learn procedure from the scan tool special functions list.
7. Follow the instructions displayed on the scan tool. If the procedure is terminated, refer to Important above for instructions.
8. Observe DTC status for DTC P1336.
9. If the scan tool indicates that DTC P1336 ran and passed, the crankshaft position system variation learn procedure is complete. If the scan tool indicates DTC P1336 failed or not run, check for other DTCs. If no DTCs

Engine Mechanical problem
1999 Pontiac Grand Am 4 cyl Front Wheel Drive 132000 miles
----------------------------------------------------------------
I have taken cranksaft pulley/harmonic balance off and there are no wires or a sensor behind it there is only the timing cover plate. So where is the cps located? Also this car stalled going down the interstate and will not start since. There was no warning that it was going to stall. It did not over heat and all fluids were fine. Am I correct in wanting to change the cps or should I be going in another direction ! ? !

Sounds like a good direction to go in. CKP is the crank sensor- 2.4 liter engine it is located on the lower left side of the engine near the oil filter

Engine Mechanical problem 6 cyl Front Wheel Drive Automatic 185000 miles

Where is the crankshaft position sensor on my 99 grand am and how do i know if it has a lead wire or not because auto zone said there is a 15 dollar difference in the part if there is a lead wire or not.

Your vehicle has 2 crankshaft sensors. The 7x CKP sensor runs to the ignition control module and the 24x CKP sensor leads to the main computer. The 24x CKP is the one with a lead wire so you will have to look over the diagram to point out which sensor you are needing replaced..

Thanks for using 2CarPros.com!

Can Someone give me the direct location of the crank sensor...1999 pontiac grand am 3.4 l v.6

Gt v6 crankshaft sensor on back of the block you can change it by removing the alternator and belt tensioner can't see it but you can feel it use a 10mm tight fit for your arm easiest way I found to do it for access.... used old tire iron between oil pan gap underneath car to work rusted sensor out to a point ...then removed it.

Hey,

Great addition to this thread! Please feel free to help out on the site whenever it can add information that will help.

Cheers, Ken

need an image of where the crankshaft position sensor is located

My info says it is located a little above the oil filter. Look at the wiring colors at the sensor connector to be sure, one wire is purple and the other yellow. The oil filter should be low on the front side of engine.

how do i replace crankshaft sensor

Hoist the vehicle.
Disconnect the CKP sensor harness electrical connector at the CKP sensor.
Remove the CKP sensor to engine block bolt.
Remove the CKP sensor from the engine block.

OBD shows PO336. Have changed crank shaft sensor, with no results. I need to get this car to pass the emmissions test! I can't find the problem! What next?

Need your engine size, liters? 3.1, 3.4, 3.8...can be wring, or PCM is no good...to accurately diagnose it, you need a scantool with two way communication...the easy fixes are ignition wire routed too close to the CKP, or a bad alternator causing electrical interference. And iff the engine speed increases by several thousand and drops back down on start up, it can be these interference issues, if speed does not increase like this, check connections at sensor, and PCM ground.

we changed the cam sensor, both crank sensors 7x and 24 x, tested injectors they work fine, we have 45 lbs fuel pressure, what could it be, car just backfires through intake.

Hi, engine cranking, if you have spark at all the plugs and you used a noid lite on the injectors, there is a pulse? Check compression, maybe the timing jumped. Any codes?

i have a 1998 grand am 2.4l and heres what happend. the starter was bad so we changed it. no bigdeal but after we did it wouldnt star for nothin to make a long story short we finally saw that the crank sensor had come unplugged we plugd it back in and wala it started. it ran rough so we adjusted the idle took it for a test drive ran great like it always has. for about ten minutes we got it home and parkd it after the test drive and were sitting in the car with it idling in park and it died. hasnt started since we hooked up a commputer to it and the only thing it gave us was P1601 Device1 serial comm link problem. what does this mean what is it were is it. please i need to get this thing running and have no idea what device 1 serial comm link is

A communication error between PCM and sensor(s). I would check the connection to the crank sensor, clean the connections with an electronics cleaner, and make sure the secondary locking pins are intact. The connector should lock into position, and you should not be able to remove without lifting the locking tang up. If the tang is broke, the connector from harness mst be replaced.

I'm trying to locate where the crank shaft position sensor on my 97 grand am v6?

It's letter J in the diagram.

1996 Pontiac Grand Am 6 cyl

If i put my car in park and step on the gas it's fine till i reach 4000rmp then it start self reving its self like if some one stoping on the gas then releaseing then stopping on it again i tried changing the tps sensor and cleaning the erg valve i also changed the crank shaft position sensor too but nothing works do u have any ideas whet it could be

If you have already replaced the throttle position sensor (TPS), cleaned the EGR valve, and replaced the crankshaft position sensor, and the problem is still occurring, there could be a few other potential issues causing the problem.

One possibility is a problem with the fuel system, such as a clogged fuel filter or a failing fuel pump. Another possibility is a malfunctioning idle air control (IAC) valve, which can cause erratic idle or high RPMs.

Another potential cause of the issue could be a vacuum leak, which can cause the engine to run lean and result in high RPMs. You may want to inspect the vacuum lines and check for any cracks or leaks.

Lastly, it could be an issue with the transmission, such as a slipping torque converter or a malfunctioning solenoid.

Does the quad 4 engine have a crank sensor & where would it be?

It's on the side of the block next to the oil filter.

We have replaced the coils and the coil housing, we have put a new ignition moldule on, new fuel filter, and a new crankshaft sensor. Car is idling funny in park don't know what is casing this, also the other day the car would start but the minute you put it in gear it would die. so we tested it again and it said crank shaft postion fault. what would keep taking the crank shaft sensor and what else can we look for that will help the car not idle so rough in park and not die when it is in gear. thank you

Remove and clean the IAC (idle air control) valve. When you removed the old crank sensor was there a shim installed? Remove new sensor and make sure there is no damage to end of sensor magnet. IAC:

Pontiac Grand AM, 1994, 205,241ml, 2.3liter,... ok one day i came home just to leave promptly when i got back in to go it would not start. It does turn over and it does start sometimes but will not run for more than a minute when i does die it does backfire most of the time. we have replaced the feul pump and filter, it does have compression and spark. we also scaned it and it said it was the crank position sensor so we replaced it cleared the code but it did not work. can you tell me what it is and maybe a way to test it if possible, thankyou for all that you can do. :cry:

If it backfires, are you very sure about the compression? Either the timing is off, check with a timing light If timing is bad camshaft position sensor needs to go...Or if the compression isn't around 140 at all cyls, stretched or broken timing chain, Or you have a few worn lobes on the cam...The last one requies you take the pipe off the exhaust manifold! Rap on the converter a few times and see if there is anything loose inside, if the converter is clogged, you can get these symtoms too...

the car was running fine when we parked it. it wouldnt start back up . Just spin. my mechanic disconnected the gas line and the gas just trickled out . no pressure on line . he put a gauge on it and it showed 30 lbs of pressure. we installed a new pump and fuel filter. we now have 65 lbs near the engine. It still wont start. he sprayed ether into the manifold and it ran until the ether was one.I have a new crankshaft position sensor to put on it. IS this the problem or is it something else?
He put a test light on the injecters while spinning the engine over and the light stay on with out flicking

we just replaced the crank sensor and it still won't start.We cant get the computor to kick out any codes. as far as we can figure out , the computor is our last and only choice to fix, can anyone help?

Ok we got it fixed. In case anyone else has this problem . it was the Ignition modular

where is the crank position sensor located on my 93 grand am 2.3 sohc

left side block near oil filter

Here is a pic

I have a 1993 Grand am SE 3.3 v6 123,000 mi I got off my buddy. He stopped driving it because he lost the water pump; it ran fine before. The car sat for about 2 years. I got it, changed the water pump and no start. Turns over and smells like fuel but not starting so I just changed the crank position sensor. It turns over fine but still no start. Coil packs? Ignition control module? Or other? How do I test packs or module?

Before you go nuts with this overheat, check the compression, ALL aluminum engines, when out of coolant, can and will warp something, a head or block...Dissable the fuel system to keep testing without washing the cylinders with GAS! Change oil and filter and put some oil in the cylinders....then compression test it!
