Knock Sensor

That is correct. You have one for each bank. Your code should dictate which bank the code is for which will tell us which sensor the issue is with. I am attaching the info on these sensors for your review. Let us know what the actual code is and we can get more info if needed. Thanks

Here is a guide as well that will help with some general information:

The knock sensor is under the intake manifold. You remove the intake and unscrew the sensor. There is a pinpoint test you can do.

DG1- CHECK KS SENSOR RESISTANCE

Note: Refer to the PCM connector pin numbers in the beginning of this pinpoint test.

Disconnect KS, measure resistance through the KS harness connector pins
Is resistance between 4.39 and 5.35 megaohms?
Yes = GO to DG2
No = For resistance less than 4.39 megohm: GO to DG3

DG2 - CHECK FOR OPEN OF KS CIRCUIT BETWEEN KS HARNESS CONNECTOR AND PCM HARNESS CONNECTOR
Disconnect PCM.
Measure resistance of the KS+ circuit between the PCM harness connector pin and the KS harness connector.
Measure resistance of KS- circuit between the PCM harness connector pin and the KS harness connector.
Is each resistance less than 5.0 ohms?
Yes = REPLACE KS.
No = REPAIR open circuit.

DG3 - CHECK KS CIRCUIT FOR SHORT TO GROUND IN HARNESS
Measure resistance between the KS- circuit at the PCM harness connector and chassis GND.
Measure resistance between the KS+ circuit at the PCM harness connector and chassis GND.
Is each resistance greater than 10,000 ohms?
Yes = GO to DG4
No = SERVICE short circuit.

DG4 - CHECK KS CIRCUITS FOR SHORT TO POWER IN HARNESS

Disconnect PCM.
Turn Key on.
Measure voltage between the KS+ circuit at the PCM harness connector and battery negative post.
Is the voltage less than 0.5 volt?
Yes = REPLACE PCM See: Programming and Relearning
No = SERVICE short circuit.

DG5 - CHECK KS CIRCUIT FOR INTERMITTENT FAULT
Key off.
Measure the resistance for KS+ between the PCM and KS harness connectors, while viewing the ohm meter, grasp the vehicle harness as close to the knock sensor(s) as possible. Shake and bend a small section of the harness from the KS sensor to the PCM.
Measure the resistance for KS- between the PCM and KS harness connectors, while viewing the ohm meter, grasp the vehicle harness as close to the knock sensor(s) as possible. Shake and bend a small section of the harness from the KS sensor to the PCM.
Tap the PCM and KS connectors if possible.
Are the resistance readings changing?
Yes = ISOLATE fault and SERVICE as required.
No = GO to DG6

DG6 - CHECK INTERNAL PCM RESISTANCE

Disconnect knock sensor (KS) harness connector.
Measure resistance between KS+ and KS- pins through the harness connector.
Is resistance greater than 10,000 ohms?
Yes = REPLACE KS. If concern is still present, REPLACE PCM See: Programming and Relearning).
No = REPLACE PCM See: Programming and Relearning.

The knock sensor for the v6 engine is at the rear of the engine block while the v8 engine has the sensor under the intake manifold. Here are some diagrams so you can see what I am talking about. (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Hello, I'm Danny.

Yes, you are correct. I've attached a picture below showing its location. Hope this helps and thanks for using 2CarPros.

Hi and welcome to 2carpros. Com

It will be mounted to the cylinder head, either the front or rear. (If I recall it's the driver's side rear head) I attached a picture of its location to help you find it.

Let me know if this helps of if you have other questions.

Take care,
Joe

Hi:
You are very welcome. Here are directions for replacement. The attached pic correlates with the directions.

1. Remove the Knock Sensor (KS).
1 Disconnect the electrical connector.
2 Remove the bolt and the KS.

INSTALLATION
1. To install, reverse the removal procedure.

The knock sensor will be located on the right front of the engine for the 4.2L and on the right side of the engine for the 4.6L and 5.4L engines. I can post diagram if you specify your correct engine size.

I attached the process from the manual to replace this sensor. Let me know if you need more info and we can dig something up. Check out the diagrams (Below). Please let us know what happens. Thanks

Check fue lpressure first if fuel injected, autoparts rent gauge then check for a vacuum leak and yes if the voltage is not high enough it could be a bunch of things like a bad ecm an dor a shorted wire. But you should scan for codes first if you can
