CEL-Throttle position sensor code w/ UTEC??
 

I just recently put an ati procharger kit on my z. totally stock exhaust, upgraded injectors and fuel pump. After dyno tuning it, check engine light is on with p1122 and p1126 codes with are o2 sensor and the throttle position sensor? Can the o2 light come on if tune is very rich? Why is it picking up a throttle position sensor code? car runs fine, but light is on?

maybe you need to go through the TPS relearn/calibration procedure.

I got something like this the other day. I think the code was p1124, but the conditions sound just like mine. I was cruising at like 30mph when the light just appeared. The car was driving perfrectly fine though! I have had the UTEC for over a year now and it was the first check engine light I have ever thrown. I used the ECU reset procedure and the code hasnt appeared since, so I really have no idea what caused it or if it will come back. I have driven the car at least 400 miles since reset, and no problems yet. Not sure what to tell you.

how do you do the ecu reset procedure or tps recalibration?
