CEL light trouble........

I got two codes today. P1400-manufacturer control auxiliary emission controls, and P0121- TPS/Pedal Position Sensor A CKT Range/Perf. Does anyone here think the problem is just a faulty TPS sensor, or is it something else?

i would try to have the sensor adjusted first. what intake are you running and turbo. i had the same codes when i was running the fpgreen with too short of a intake tube. i think there is a tread on here about it.

If the TPS was going bad or is bad, I would think the car would run like poo.

I've been running a stock manifold Buschur kit for about 2 1/2 months now. Never had a problem until today. I think it just took a crap.

try to recalibrate the sensor first. much cheaper and might fix the problem

You should try and post this in the tech section... You might get better feedback. I would say, change the sensor, it prob went bad...
