What could cause a tps sensor to go out fast? I put a new tps on my truck and a month later boom it went out with no warning while i was driving. What could cause this?

 

90% of the time if it fails that quick it was faulty from manufacturer...

did you put it in or did a tire shop?

 

i put it on

 

my guess it would be faulty from manufacturer..

id say try another tps unit, as well as checking the electrical connections for it.

what size motor is this truck running?

and when i asked if a tire shop put it on, i misread the post and thought u had said TPMS... my b dood..

 

1998 5.2l and i put a new one on it and it is running fine but i don't want it to happen to me again while i'm driving. It sucks driving in town without being able to let off the gas. Also how would i check the connection for it?

 

unplug the harness, and check it for corrosion, from what i've seen, corrosion is a big factor in electrical parts failing, as for voltages and things of that nature, a little outta my league. usually when there's corrosion, its acting as a resistor, limiting the amount of voltage and amperage to pass through the circuit,

 

idk if your local auto parts has a good code reader but the one i bought has a reading of the tps so if you dont touch the gas it will read 0 and with key on engine off you floor it re read the sensor and it should have a almost 100% reading 99% of the time i get 99% for working properly
