do you take it to a dealer? Sometimes there are updates to the ecu that need to be done. we have the same engines in some of the kia's, can't remember if we have tps issues with those engine's. Might be worth taking it in and seeing if there's any TSB's.
I had a leaky injector(s) on a vehicle that exhibited those symptoms I described. But if yours fires up probably something different. Tps could have a bad spot on it. Does it have a maf? Do you have a vom meter? I dont know what signals should be sent to the Tps and maf but you could check. Google is your friend to see what should be read.
Tps is plug and play. We have a tsb on some of them and the tps cost like $3.00 because it is a common problem, this mostly effect 3.3 and 3.5L engines.
I spoke to a Hyundai dealership. They said there is no separate TPS. The throttle body is one piece and cost $500. This is BS. How can Hyundai make the TB and TPS one piece? How often does a TB go bad? Sensors go bad ....not the TB. The part number was 35100-3E100
Our price is 415 on the TB, its one peice. I would go to the dealer and verifiy there is a problem first. Or find some one with a graphing meter and look at the waveform the sensor is producing. No sense in throwing 5 bills down the drain.
That's drive by wire, no throttle cable? TPS should set a code with all the redundancy in sensors. Don't overlook a dirty throttle bore, can act the same way as a bad TPS.
I'll clean out the TB first. Hopefully I can find someone to test it first. At first I was thinking......just get a $50 TPS and cross your finger. Thought it would be a cheap trouble shooting technique.
No codes, put a scanner on anyway and double check .
they are famous for the variable valve timing problems.
THe oil control valve goes bad or gets clogged
