About 3 weeks ago my Check Engine Light had come on. I went to a local shop so they could tell me what the code was, and it turned out to be for the TPS sensor. They quoted me $500 to replace the sensor as well as running diagnostics and testing for an hour. I went to another shop a few days later and got a quote of around $400 to replace the whole throttle body. The light came on during a very rainy day, so I'm thinking maybe some water got in there and shorted out the sensor.

Anyway, the Light came on and off a couple times during the days after that but hasn't come back on for over 2 weeks. Only when the Check Engine Light was on would the car drive funny, otherwise it drove normal. One mechanic did warn me that a faulty TPS sensor would cause me to fail emissions... but I'm not even sure if it's faulty anymore considering the Check Engine Light has been off for weeks and it's been driving just fine. Also I should note when I was having the problem, turning the engine off and back on would fix it everytime.

Is it possible that my TPS sensor will still show up as faulty on an emissions test even though the car drives fine and the check engine light has not come on in weeks?

 

I don't think they check for codes, do they? (I don't need to go through emissions)
If the light is off, you should be okay.


If you're worried about it, you could always have Autozone (or another parts store) check for stored codes. They do it for free.

 

ive had that problem before. it usually happened when it rained really hard, and most likely, something had gotten wet and caused the check light to come on. mine drove just fine wiht it on.

 

I'm just trying to figure out if it will show up on some sort of test, despite the Check Engine Light not being on. I doubt they would hook a multimeter up to my TPS sensor as standard procedure, unless the the Check Engine Light was on.

 

emissions testing procedure depends on where you are located...

where i am, all newer cars are just scanned for obdii codes...if you were here and the code is still stored as pending or active, your car would fail.

on older non-obdii cars, they run the car on a dyno then measure the emissions.
