P0227 Throttle/Pedal Position Sensor/Switch C Circuit Low Input
P1612 NATS
But what's crazy is that P0227 code comes up twice. My mechanic knows that P0227 usually means the pedal assembly needs to be replaced but with that NATS code he doesn't know what to make of it. He says it could be the pedal or it could be the ECM/ECU. He used a voltmeter and got 5 volts on pins 106 and 98 on the pedal so he said the sensor should be working so it should be the ECM. That being said, he doesn't know for sure and since the car idles fine he doesn't know if its the ECM.
He wants me to buy the pedal, a $300.00 pedal, and $200.00 to install it to check if that's the issue and if it isn't he wants me to buy the ECM and that's another $500.00 and I have to go get it programed by a dealer. Does anyone have any advice or tips for me? Does anyone know how to check for a bad ECM? Would there be a code for that?
The car is a 2002 Infiniti I35 which is basically the same car as a Nissan Maxima.
it is important to note I had a similar issue 2 years ago. Back then switching the pedal worked and then my car worked. I switched my current pedal with the old one to see if it's the same issue and the old pedal wouldn't even rev the engine (this current one revs it to 1.7ish RPMs). This leads me to conclude my current pedal is working and there's a different issue. :/
