neutral safety switch?

Hello,

It happens. The problem is that without the original starter to test there is no way to know. This guide will help you check the starter with diagrams below to show you how to replace the neutral safety switch.

Check out the diagrams (Below). Please let us know what happens. The 4 and 6 cylinder cars are the same

2003 Honda Accord 6 cyl Two Wheel Drive Automatic

The gear is stuck in Park postion and you have to engage the button on the sifter numerous times in order for it to move to reverse or drive.

Hi beav44,

Seems the interlock system is causing the problem.

With ignition switch turned ON and depress the brake pedal. Listen for a clicking noise at gear shift. If the interlock solenoid is clicking and you are not able to move out of Park, you would have to check the solenoid.

If no clicking noise is heard, check if the brake lights are working. A faulty brake switch would not operate the solenoid.

The shifter isn't functioning..

More than likely this is not the range sensor but the shift interlock. The range sensor just tells the PCM which gear the transmission is in. If it is not in park or neutral it will not allow it to start.

If the shifter is not coming out of park or the shifter button (if equipped) is not depressing then this interlock is the issue.

I attached the info and testing if you would like to prove this out. However, if it were me, based on this info I would just go ahead and replace the shifter. You can also find quite a few videos online that show people fixing this switch. I have not had long term success with this so I would just replace it.

Let me know if you have questions. Thanks

Okay, the shifter moves the gears are not entering it's in parking sometimes it gets revers or not it gets neutral the D jumps to D1 or D2.

Okay. This could the range sensor if it is not adjusted properly or is failing. However, it normally causes a no start. Have you check the transmission fluid to make sure that is full and in good condition? That would be a more likely cause of this.

Here is a procedure to test the TRS and replace it. There is a process for making sure it is installed correctly.

Okay, as soon as we connect the range sensor sensor we make sure the put the gear in parking and turn the key to make sure the parking light displays in the dash, but when I shift the gears they skip gears or some won't display in the dash.

Sounds like it is out of alignment. I am attaching the process. Just run through it and make sure you had each position correct when installing it.

Engine light steadily stays on got it checked out and got the code p0705 and p0706. My tcs lights also come on. Are they related and could it be caused by the neutral safety switch ?

Yes, the PNP is the culprit and it can cause the TCS indicator to come on.
Check the PNP wire harness conector for contaminations and looseness.

thank you very much

You're welcome. Let me know if you need anything else.

My question is if the neutral safety switch can have any othe effect on your car other than it starting out of gear?

Issues with my vehicle include:
-throwing off a P0607 and P0420 codes
-when I attempt to accelerate it acts as if it doesn't want to shift gears
-my RPM's are spiked (running, but in park reading roughly 1000RPM)
-when I attempt to accelerate it also whistles, but only when I press on the gas
-have to really push it to go over 40mph
-no smoking, no bad smell, I am due for an oil change soon, only sythetic oil

Those may not be the correct codes so don't pay attention to those

The neutral safety switch is used for preventing the engine from starting when in a gear besides park or neutral.
It sound like you could have an exhaust restriction. I know you said not to pay attention to the codes but if you have a P0420 code this could indicate your catalyst is plugged. A vacuum gauge should show a restriction when reving the engine. Does the engine run well when parked? Rev the engine up to 2500 RPM does the engine run fine at this speed?
Another way of checking for restricted exhaust is to removed the catalyst from the vehicle and drive it to see if it runs any better. The engine will sound really loud without the muffler. Don't drive the car very long without the exhaust connected as the exhaust gases are toxic and extremely hot.

When I tried to do that in park today it acted like it wanted to stall on me even though it's an automatic. And no it doesn't run good at any RPM

That really sounds like plugged exhaust. But I would like to know if there is codes what they are because a faulty sensor could cause this but is less likely.

Transmission problem
1993 Honda Accord 4 cyl Automatic 200,00 miles

I have a 1993 automatic transmission accord, it has problems identifying in which gear it is driving, took it to the mechanic he said it gave him a code 5, but it's not giving any other information. The mechanic mention neutral switch or ground problems.

Hi snvasquezd,

DTC # 5 means
1. Short in Shift Position Console switch wire.
2. Faulty Shift Position Console switch.

The problem would result in gears shifting only between 2 and 4.

Does the meter indicator lights for the gear shift positions indicate the correctly?

You need to check the switch which is located under the gear shift console.

where is the neutral safty swith on this car. on hot days some times it will start and sometimes not. but it always cranks. when it will not start i have to trick it by turing key to on position put foot on brake then slide shifter to reverse then hold key to starting position and slowly slide shifter towards park and in the middle it hits a sweet spot and starts. go figure? so what is the component causing this problem.

Check and test the shift position switch and the ignition switch-see below

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

how do you get to it and out it on i have the part and need to put it on

Hi johnathancook89,

You need to remove the centre console. It is attached to the side of the gear shift assy.

Make sure adjustment is correct by testing the positions before assembling of console.
