I was taking a small road trip, cruising down the freeway and all of a sudden, I lost all acceleration power. I took my Z into the shop and ran a diagnostic test and it came up with three (3) different codes:

Code 2122 - Accelerator Pedal Position Sensor
Code 2138 - Apps Range Problem
Code 1229 - Sensor Power Supply Circuit Short

Is this a common accurance on the 2003 350Z? Does anyone know if Nissan will cover the cost under the extended warranty? Any advise would be grateful!!

Thanks!

 

Same thing happened to me. What was the problem?

 

Go to the Technosquare website and try the reset on the ecu and learning procedure on the accelerator pedal release position.

There is the problem. The pedal doesn't work when you have this code so their is no way to press it. I actually sent my ecu back to technosquare and Brian reflashed it. It was getting a couple weird checksum errors. We think it had to do with running the car with a very low charged optima battery.

 

was everything okay after reflashing your ecu?
