I searched through the fault code thread, but didn't find what I was looking for, unless I missed it.

At any rate, my car is a 97 Nissan Maxima SE, 5-speed, 161k on it.

I have had my check engine light on for a while now. Haven't noticed any real decrease in MPG or anything running all that weird, so I didn't worry about it too much.

Went to Autozone today and got my code checked out and here is what it reads:

Park Neutral Position (PNP) switch fault

Probable Causes:
1-Open or short circuit condition
2_Failed PNP switch

Any suggestions on what to look for or how to correct the problem?

It doesn't sound that serious to me. But I'd like my check engine light turned off.

 

See Sig............ You can get it at VQ35DE.com.........

HAHAHA, I had this long response typed up about checking and re-setting the nuetral position on the inhibitor switch, lol, silly me, you're stick.........

Yeah that code won't affect any engine control, it is more than likely a fault with the actual sensor on the trans. If you haven't changed your gear oil recently (or at the last trannsmission rebuild ) Pull the r/n switch to change your gear oil, clean the copper contacts for the switch both on the big round plastic part and use needle nose to reach inside tranny and pull that part out and clean those also. Very good chance it's all covered in nastiness, you can aalways test with an ohmmeter before filling up with fluid in case for some odd reason you do need the sensor.

 

How do you figure? Guess them VQ35 guys with the precats shouldn't bother, eh?

 

hahaha, don't make me pwn you...............


Read the 2nd part........ it applies to a33's as well

 

A33's don't have VQ35s.

 

omg, to easy.....

Sorry, I should have said a33a/b's

A33b's have VQ35's (02-03 maxima)

 

I know A33B's do, my point was that A33's dont. In any case, headers are beneficial for A33B's, which have VQs. So I don't see how you say they're worthless.

Anyway, I was just ****ing with you. Carry on.

 

hahaha, don't do that! I had a long **** day, but yeah, I agree, pre-cat's FTL, but why not just pick up some a32 manifolds and y-pipe as opposed to headers, no dyno has yet to prove either is better...............

 

So no one has any advice on what it will take to fix this?
