Hyundai Sonata Gas Problem
Asked by tracyschultzAnswer
why did you replace the tps???
Roy
my car was idling high and hesitating when i was pushing the gas and then my check engine light came on and that is what the code was.
codes never identify bad parts, just failed systems. it needs to be monitored to see if it is wiring, grounds or the sensor or pcm. throwing parts at it is expensive and usually wrong
was the trans ok before you replaced the old tps??
Roy
Yes the transmission was fine, just the hesitating while pushing the gas.
first thing i would do is put the old sensor back on and we start from there.
need to check fuel pressure first.
timing belt, when did you last change it??
cat converter back pressure would be next
always start at basics. do the checks, find the failure and replace the failed part.
