2001 Chevy S10 Xtreme 2.2 - Low Voltage from Throttle Position Sensor on Cold days.
On cold days (below approx 25-30 degrees F, the car starts but idles a bit on
the high side. After the car comes up to temperature, I loose all acceleration.
Doesn't stall, just no acceleration. I turn the car off, start it back up, runs fine.
No problems. The error P0122 showed up, low voltage from the throttle
position sensor. Had it replaced (the throttle position sensor), same
problem...ONLY on cold days after the car just comes up to temperature,
again turn the car off. Restart it....runs great. I'm going to have the wires
check next I guess, however.....I know the cold has some effect on wires &
connections, etc, but it seem weird that it's only on cold days and all I have
to do is turn the car off then restart after it comes up to temperature then the
car runs great. Seems if the wires were bad or a bad ground it would happen
sporadically regardless of temp outside and restarting the car to fix......Any
else to check beside wires? Is there any way the new TPS could be bad,
doesn't seem likely to me....Let me know...Thanks!!!
