Thread: Loss of power when warm?

Wish I could help mate. Good luck.

On a cold motor it's a 5min job to replace.

If it is the CPS then pouring cold water over the rear of the engine when it is playing up should fix it temporarily

Unless I misunderstood, wasn't he said about him finding the TPS bolts or screws broken, or at least loose, at the top-rear end of the engine near the induction area. If they were broken and the sensor was floating around then the symptoms would be about right, but this was originally a 2012 thread.

If the loose TPS isn't your current issue, I have recently installed a new CPS in my 150K 2000MY P38 HSE 4.6, which is a Bosch sensor and may not fit on your GEMS engine. My Bosch original sensor was just fine but I've kept it as a spare as some fail early and others later.

If you want to you're welcome try it on yours for the price of shipping both ways, which I don't know at the moment. It's a bit of a fiddle replacing at the back of the passenger side of the head, and I broke part of the plastic clip the locks the cable to the loom (but NOT the loom bit - thank goodness), but I'm sure it's working well to test yours. Let me know.

CPS' are not interchangeable between bosch and gems engines.
