The tps throttle position sensor check engine code keeps going off while driving. When the tps code goes off the engine loses total power and you are unable to accelerate, which is a safety issue. We have replaced the throttle body but the issue is still remaining even after replacing different wires.

The speedometer stopped working,as well as the RPM indicator at approx. 26,000 miles driven on the pickup.. I have learned there was an extended warranty on this defect rather than a recall. I never received the letter advising me of this from gm, although I owned the pickup since 2006. I stopped driving the pickup because it was not safe to be unable to ascertain how fast I was I driving. I learned about this defect when I called a dealership to discuss the repair last month, as my vehicle was not usable. I then called gm and they said the extended warranty had expired. This is not fair, and has rendered my vehicle unsafe to drive without a high cost to me for their defective part. I request that they cover their defect.

I was driving on a down hill road with a stop sign at the bottom. I began to press the brake and the pedal went to the floor. I could not get the truck stopped and ended up in an empty field to avoid a wreck with impact. There was a huge wet spot on the street where by brakes failed. Very scary with my young children in the truck with me. The brake lines were all rusted and had given way. According to the repair shop (and the internet) this is a known issue with these vehicles. I am also now having an issue with my instrument panel going crazy. The speedometer will say I am traveling 110 when I am rolling up to a stop sign. The fan blower will be on 0 and it will blow out at full force and will not turn off, even after the engine has been turned off. This ultimately results in a dead battery. I have had to have several jump starts. This issue according to my mechanic is a "known issue" with this vehicle. However, my VIN # produces no results for recalls. So like my silverado break down on the side of the road issues, the search results have left me stranded as well, only this time I am not walking down the road with my small children.

I left my home and drove approximately 10 miles before pulling into a parking lot. I was away from the vehicle for about 45 minutes.upon starting the vehicle I depressed the brake pedal and engaged the transmission. At this point the pedal seemed to travel further than usual. I left the parking lot and drove about 200' before having to stop; this time the pedal went to the floorboard but slowed the vehicle somewhat.(at this point the dash showed a check brake system).by driving under 30 MPH I was able to get the vehicle to the chevrolet dealership. The lines were rusted as were the calipers. Parts and labor=$1700 the truck is 12 years old with only 26,910 miles on it.

I own a 2003 chevrolet silverado and as I am driving down the road the check engine light comes on as says "reduced engine power" and I am only able to travel between 20 to 30 MPH and also as I come to a stop light/sign the truck wants to sputter out and die. Everytime I take it to a mechanic shop they tell me its the throttle body and that it needs to be changed but I have already changed it 4 times in the last two years and is not the problem. The problem is constantly happening sometime 3 to 4 times a day.
