Ok... I've been haering a lot about this fella lately, how it could fix some idle/hesitation probs... well isnt this thing an electronic component?? heard that it should be replaced at about 90000 miles, well either an electronic things works or it doesnt, should it wear out like something mechanical would?

Just wondering b/c my max is hesistating and I dont know if the $130 price tag on this fella is worth it

Just venting or something

 

$130 is too expensive. i got mine for $36 and change. it definatly made a difference with the hesitation, but the car still randomly wont start. what the hell :grr:

 

The throttle position sensor works on resistence to tell the ecu when the throttle is closed or at WOT. Any electrical component will break down over time giving false signals. So it does 'wear'over time.


Brent.

 

are you talking about the Mass-Air Flow sensor, or the throttle position sensor?

MAF sensor is about $600 new from a dealer.. probably $130-150 salvage yard prices.

the TPS is about $60 new from a dealer..

both can do weird stuff, but the TPS is the easiest to test and cheapest to replace. start there, then try to narrow the problem down.

 

matt, maybe you can help me out. i just replaced my TPS and the car started running great. well, last night i go get in it to leave my friends house and it wont start. it'll crank, and just not sputter or catch or anything. like i've been saying (and no one can seem to figure it out) when it doesnt start, i cant hear the humm from the fuel pump when the key is in the "on" position when the car is cold. well, today, i got in, turned the key to "on" and heard the hum, so i told my friend it was gonna start, sure enough. it did. when it isnt starting i can still hear the pump relay clicking on and off with the key. i was thinking a bad MAFS (this all seemed to start when i took the MAFS off to clean the throttle body) but thought maybe just a tempermental fuel pump. help PLEASE.
i thought i had this problem fixed
