Question about 2002 Oldsmobile Bravada

1 Answer

Cam position sensor

Check engine light comes on for a few days, goes out for awhile, then back on for days. Autoscanner says the trouble code is the cam position sensor. Friends say if the sensor really is bad then the truck wouldn't run at all because that sensor controlls fuel injection and spark synchronization. I can clear the code but the light comes back on later. The truck starts/runs fine other than the damn light. Could something really be wrong with this sensor and the truck still run ok?

The cam position sensor tells your computer when the #1piston is in position and your vehicle will not run without it as it would not know when to fire the cylinders. However, you could be having intermittent problems with it which means it is failing but hasn't broken completely yet. Since you have a code in for the sensor I would check the wiring and connection. If all that looks ok then I would replace the sensor. Better to replace it before it completely fails and strands you someplace.

Check engine light and airbag light came on; now car will not start


I have run into this problem a few times where the dealer replacing the sensor and a month later light back on, take car back it may need a program update and sensor may be bad or crank sensor may need replacing.
I would have the code scanned at a local auto parts store and if the code is the cam then take it back to dealer to see what has happened.
The car i was working on had a cam sensor problem, replaced the sensor and light came back with same code. sent to dealer and dealer said after market part was bad, car needed an oem part, so they replaced it and in a few days same problem . took car back and this time they installed a program update and so far so good.

2007 Tahoe has check engine light on and can not used the remote starer either. reset codes the remote starter work until check light came back on code said cam sesenr fault car run fine


there are several reasons why the remote start won't work, and one of them is the presence of a check engine light. Normally a check engine light comes on when a trouble code is present and recorded by the engine control module. Resetting or erasing the codes can only bring temporary relief, like what u said the remote start worked again. But the trouble will still come back until the real cause is being addressed. You got code on the cam sensor, but car runs fine. Its because the engine computer senses inconsistencies while trying to improve the Emissions system of your vehicle. That we cannot see or hear. Most probably your cam sensor or the wirings are getting intermittent. Better have it visually inspected and replaced if necessary.

Probably the sensor. Hair line crack in sensor can cause the check engine light to come on .When the sensor gets hot it expands and causes a fault reading.

try by starting off with getting a computer scan for diagnostic trouble codes.ther should at least be a history code stored. it sounds like maybe a cam sensor problem , but the scan should shed more light on the course of repair.
