My 2008 SRX also had this problem, at first I would turn the engine off and that would fix the problem, but then both the check engine light and the reduce engine power light would come right back on. I brought it to my local mechanic and the code that came up was for the timing chain or the crank shaft. They checked with cadillac and they had problems with timing chain so that was replaced. It was fine for a few days and is now doing the same exact thing. Can anyone help?

My 2008 cadillac srx engine light came on and engine power reduce took it to the dealer so they changed the crank shaft sensor but its still not working, can you please help me


if they didn't read the fault codes before starting work, they are repairing by replacement and that is not good
if a sensor is faulty and it could be a cam shaft sensor as well as a crankshaft sensor , normally it misfires or stops altogether
the ECM is in limp mode and that reduced the engine power and if there was a sensor problem it would not just reduce power and put the light on but would show up in a define manner
engine lights also come on it there is a transmission problem and that will also initiate the limp mode
have the fault codes read to determine the faulty part/ sensor

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck
