#377 of 386 2006 Canyon Reduced Power by sean91 Oct 19, 2009 (7:34 am)
My wife and I bought a 22,000 mi 2006 Canyon from the original owner in May. The REDUCED POWER and EMISSIONS lights came on a few months ago. I pulled over and restarted the car. The EMISSIONS light stayed on, and as there was less than a 1/4 tank I thought it might need some clean gas. After filling the tank the EMISSIONS light didn't come back on. But last week my wife used the truck early in the morning and she told me after that the REDUCED POWER light came on for her and the truck wouldn't respond. A master mechanic friend at a local gas station did a free diagnostic and found the report: P2138 ACCELERATOR PEDAL POSITION (APP) SENSOR 1-2 CORRELATION. He said it was a sensor for the gas pedal or perhaps the whole pedal unit. I took it to the Morgan GMC in Shreveport (ironically) where our other friend purchased it, and they want $95 just to do the diagnostic and at least a few hours wait just for that. So I said I'd come back. Instead I am researching it further here....And the Morgan dealer service rep informed me that the manufacturers warranty had run out in April 2009...we bought it in May. The seller said it ran great. But I am wondering if our seller "friend" may have had the signal as well. (I can't call it a "problem" yet as it has only happened twice.)

Has any one had a problem with the welds breaking at the exhaust manifold and pipe. It happened today coming from work. I hit a bump and went from quiet to race truck. Called the dealer and they wanted to replace the exhaust manifold and I asked is the pipe already welded on and he said he didn't know ???????? So I called a muffler place and there going to look at it tomorrow. He said if he can get in there to weld he'll do it. I hope he can..........Zippy Replies to this message: zippy78 (Oct 20, 2009 4:23 pm)

Replying to: sean91 (Oct 19, 2009 7:34 am) I would do further diagnostics. If there is something wrong with the emissions system (catalytic convertor, power module, etc.) it's still under the emissions warranty which runs for 5 years (?) or 80,000 miles (?). Check your warranty booklet for the items covered by the emissions warranty. I had an S10 that was over 4 years old and had over 70,000 miles and the catalytic convertor was replaced free of charge because it was covered by the emissions warranty. Good luck.

Replying to: zippy78 (Oct 19, 2009 5:17 pm) Well no welding. Theres another converter thats apart of the exhaust manifold. They got to replace the exhaust manifold which will cost over a grand. The warranty is 8 yrs/ 80,000 miles. I got over 85,000. SUCKS. This is the first time I had to sink some money into this truck, so I feel pretty good about it. Hope this doesn't start a chain reaction. later zippy
#381 of 386 Differential and Driveshaft by biker15 Oct 26, 2009 (5:34 am)
I have a 09 chevy colorado with 1863 miles on it two months old.On saturday Oct 24 I was on the highway when all of a sudden I felt a shudder in the truck I thought it was just the wind so I kept going about a mile farther down there was a explosion under the truck sparks and smoke all over.I thought i blew a tire when we got over to the side of the road all tires wer all right.i discovered the there was no drive shaft under the truck and the front end of the differential had been blown off. I had the truck towed into the dealer and awaiting word the truck is brand new with one thousand eight hundred miles on it.I am wondering if anyone else has had thi problem Replies to this message: Mr_Shiftright (Oct 26, 2009 7:02 am) biker15 (Oct 27, 2009 3:16 am) Mr_Shiftright (Oct 27, 2009 6:45 am)

Replying to: biker15 (Oct 26, 2009 5:34 am) Well that sounds like a royal assembly line screw-up at best and a part failure at worst. I'd report that one to NHTSA asap. You are very very lucky actually---this type of failure (which I have seen now and then even on very expensive cars) can cause real mayhem---either the driveshaft coming through the floor, or half the driveshaft hanging down, causing a "pole-vault" effect to flip the vehicle over.

Replying to: biker15 (Oct 27, 2009 3:16 am) Very dangerous situation. If you hear of any other similar occurrences, please let us know. Perhaps there's something brewing here --although for the sake of other drivers, I hope it's just a one-time glitch.

#386 of 386 Re: 2006 Canyon Reduced Power [jpf] & check engine light by lbdjr Nov 03, 2009 (2:09 pm)
Replying to: jpf (Oct 20, 2009 3:53 pm) Similar problem with my 06 Colorado (I-5) rwd crew cab. The car would indicate reduced power and just die at stop lights. Turning ignition key did NOTHING for about 5 minutes. Then it would start and then die on me. At 35,000 miles and 3 1/2 years ownership car was out of warrantee (or so I thought). I took to Advance Auto for free check eng. code diagnosis which was "P0601". I googled the trouble code and learned it was the "PCM Control Module" or brain for the engine. Because this PCM has everything to do with emissions the PCM has a factory warrantee of 8 years or 80,000 miles. The Chev dealer replaced it at no charge. Car runs fine once again...hope it lasts. I hope this info might be helpful to other Colorado/Canyon owners.
