Check engine light came on about a month ago read a p0122 throttle position a circuit low and so i reset it and it worked until today. Dodge wants 650$ for a new one, but I found the aftermarket one at geno's garage for 200$. Has anybody used one from them and will it work on my 5.9 24 valve?

 

just went threw the same thing, with my truck i ended up going to autozone and getting one for 200$ they had it in stock, a few days later a buddy of mine had the same problem (dead pedal) and ordered one on ebay for 20 bux if it was now i would have just gotten a cheap ebay apps..

 

Do cheap TPSs work? Where do I look for this info?

 

Timbo Apps http://www.dodgecumminsapps.com/index.html[/URL] You might check this one out. A thorough check on the alternator is a good idea before getting in a big hurry to replace the apps. Frequently dirty voltage is the cause of problems, and no advance/autozone can't tell if your making dirty power. The alternator output can be fine and still be noisy with a.c. voltage if the rectifier is crapped up. It will jangle the ecm inputs/outputs and make it forget apps set points as well as cause trans shifting problems, etc.
