I am not sure what your problem is with the sensor, but if you just needed the light to go off so that you can pass inspection....you could turn your ecu into test mode so that no codes stay and the light won't be on. I believe that is 1/2 way around on the knob, so the dial is in the middle.

He can't do this if he lives in a state that does OBDII emissions testing. Where I live (Pittsburgh) there is no tailpipe test anymore. The emissions tester plugs directly into the OBDII port on the car and scans the logs for trouble codes, pending trouble codes, and monitors. He will fail because not enough of his OBDII monitors will be set if he resets his ECU.

Yeah right.............you find a shop that will do that.

Any garage or mechanic in PA that gets caught doing that is in deep $hit.

Thank you all

Thank you all for your messages.

I had another auto shop checked my car today. And they said if over the weekend the light does not come back and they will do the state inspection again for my car. Well, hopefully by then, my car can pass the inspection.

The big headache is if the light comes back on after few drive cycles, I have to send it to the Nissan dealer and it may cost $$$ to fix the same problem. What if the same problem comes back again later on, say three months? I have to face it every year near the inspection time. Sigh!

I can ONLY HOPE the BEST.

The problem should be somewhere in the Neutral Position switch, Inhibitor switch, shifter, or harness.

Isn't state inspection fun? It's the best time of the year.

Look on the bright side, you have an OBDII(2) compliant car..........
wait until you see what they have in store for you when OBDIII(3) comes out.

Seriously, good luck.........if it came back after replacing the inhibitor switch, it will probably come back again.

This is an automatic, correct? Did the transmission guy say anything about the PNP?

Stupid TRS Circuit Malfunction code. What a headache

Hahahahah. i looked all over the internet for that code to see what the hell it meant and what it was.
It's a code that checks if your gear is in the neutral position.
My car is getting that code too because i put in an Autostarter/alarm system.
In order to prevent my car flying ahead (because the clutch has to be tripped), a wire is spliced into the TRS to check if the gearbox is in neutral.
Solution:
My friend/mechanic was saying to put in a diode into the spliced wire so the electric current doesn't go back into the TRS circuit.
But in your case, just make sure the wire is in good condition and that it's making a full circuit.
