diagnostic codes!

[silver03cobra]

My car is showing 2 codes!
P0068 - tps (out of no where!)
P0481 - Cooling Fan 2 Control Circuit Malfunction

Any ideas on the fix?

do you have your fans on any kind of switch? you can turn them on b grounding the wire to them from the pcm. could be hsorting somewhere. also do you have a wideband or something that uses a signal from he tps? you can run into these problems if done wrong or again if it shorts.

good point.

I had the car dynoed 7/25/08 and now the car is having problems. I think it is because my dragon Tb does not close all the way. It idles at 1500 might throw the tps off. The car dies at WOT... If i punch it to wot it acts like a slipping clutch (but does not rpm.) If i go easy to wot it will run great! My sct2 has the idle set at 800rpm but the car idles at 1500. you can reach under the hood at push the tb closed. Then it will idle around 950rpm

Those all seem to be fuel control codes (the last three) all roads point to PCM -
