A week ago, after working on the truck (96 kingcab PU 2W drive) I got the IAT sensor error code. I found that one of the wires to the IAT sensor connector attached to the bottom of the air cleaner had broken. I soldered the wires together, disconected the battery, both terminals, ( I also touched neg and pos cables together) .
Engine light is still on!
Car runs fine with or without the wires connected together.
Any advice appreciated!

I reground the earths on my primera (UK), that put the engine light on and the car ran ok. The light went off after 2-3 days. hope that helps. Mike
It stay on until someone turns it off or the car goes through enough cycles with the problem fixed.
Thanks,
Can I turn it off or do you need a special tool?

Maybe disconnect the ECM for an hour or so and it will reset itself.
It can be reset with a code reader or it will reset after 50 start-ups. (if the problem is fixed)

Also you can do it at the computer on some models, you turn the code screw one way then the other. Disconecting the battery doesn't work.
I have a 97 truck that had the same problem. I bought a sensor to replace it only to find the wire connectors were bad and the sensor wasn't the problem. Check your wires first and you might save $80.00 for another sensor. To after you fix the problem you can reset the computer by disconnecting the battery for about 5 minutes then connect it back up again. I was later told that there was a recall on the sensor connector for my truck. You might want to call a dealer to see if you vehicle has the same recall.
