#278 of 483 2009 impala traction control/power reduced
Feb 01, 2013 (11:38 am)
Man so many replies top this message, my impala has 44,000 miles and is a 2009. Seem to be different fixes for same message. Unless I'm misreading. So a little confused. Replies would be welcomed. This is a scary thing to happen driving anywhere. My dealership is one that went by by. So not much help, was purchased new late Oct of 09.

Depending on the code your car is throwing when it goes into Reduced Engine Power it can be several different fixes... P2138- Accelerator Pedal Position seems to indicate a bad Gas Pedal Sensor(Which isn't covered outside of the 3 year 36k bumper to bumper), P2135 a throttle body problem, more specifically Throttle Position sensors not agreeing on a voltage. So have your codes read at the dealer or an Auto parts store (usually for free) and it will indicate which problem you're having... my 2009 was throwing a throttle body code and the dealer replaced mine for free under the 100k mile Powertrain warranty, after 2009 they removed it from the powertrain warranty. After replacing the throttle body it still persisted, so We've kind of narrowed it down to a bad battery or bad wiring to the throttle body. If you've read previous posts the gas pedal is an easy 70$ self-fix that involves removing some bolts, plugging the new pedal in and putting the bolts back. I would go get a free scan at a parts store before taking it to the dealer, as my diagnostic fee at the dealer runs 100$.

Im having the same problem with my Chevy Traverse. GM really needs to step up to the plate and do a recall on this issue before someone gets killed in an accident. Same problem seems to be happening in the Saturn cars and Equinox too! Hey GM since you monitor these boards, YOU need to fix this problem now!!!!!

Now I am having trouble again with my Impala - just had the gas pedal replaced - now apparently it's the gas caps or something. This is ridiculous. I think I"m going to write a letter to write letters to newspapers and tv news shows. If GM is not going to do anything - we need to start doing something.

Battery didn't help after a weekend test drive "Reduced Engine Power/Service Throttle" were back, My dad started tracing wiring and found this in the PCM Box.
PCM Pic 1
PCM Pic 2
PCM Pic 3
The Blue in the terminal is a bunch of Icemelt salt that had found its way into the airbox with water and rode the wires down into the PCM plug and corroded some terminals, including the Throttle body wire connection. He cleaned the terminals with air and got the corrosion off them and the gunk out of the plug and got the moisture out and for 3 days my car has been running with no hiccups even when the traction control has kicked on a bunch of times on slick snowy roads (which caused the reduced engine power before) The PCM is located in the bottom of the airbox as it requires air to cool it, although it doesn't require salt. Someone who owned the car before me apparently had the PCM box off ripped a gasket and put it back on with half a gasket. Luckily so far it doesn't seem like permanent damage was done to the PCM.
