cam position sensor?
What does the cam position sensor do?
Would an oil film on it affect its operation? Anyone help please Thanks, Keith |
the cam sensor lets the ecu know when to fire the plugs, as for oil on the sensor im not sure if it would effect it as uses magnetic waves to read, now i cant confirm all of this as im still learning this stuff, just trying to help keith :)

Thanks for the response...

If it is already worn out....

I would think it would show a code. I just replaced mine in my Outback. The car had no power and would hardly run. It was like it had a clogged fuel filter, but worse. It turned out to be the cam sensor. :o

I just replaced mine in the SVX. All hell was breaking loose, melting cats, killing O2 sensors, you know...fun stuff. Turned out it was a bad cam sensor.

The cam sensor works together with crank sensor #2. By counting the number of pulses from each sensor, the ECU can determine the current position in the firing order, in other words, it can figure out which cylinder is supposed to fire next.

Did you pick up a Cam Position Sensor code? This is the sort of thing I was suggesting in your Major Power Loss thread. I was trying to save you the trouble of stripping the cam gear to check the belt, but I'm thinking you probably enjoyed the learning curve anyway. :rolleyes::D Good work so far. Joe:) |
Didn't get that code but got a 37

I have the car at the dealer since monday and they can't work out the problem! They say one side of the exhaust system is getting hot, about 500 degrees and the other side is pretty cold... 120? I already took the cam sensor off my "doner car" and am going to take it to them to try this am! Thanks for the input Keith |
sounds like a jumped timing belt
|
Did to me too!

A mile or so later... Another dream... A NIGHTMARE Could a jumped timing belt drive me for a mile like a dream. I can't find any logic for that:confused: Wish I could I need that car to work bad my dd 1t least 100 miles ever:(y day |

The other thing Keith is a damaged or blocked cat. Sometimes they disintegrate internally with age or they get a thump from a rock or kerbstone. If the gas can't get through the exhaust will get really hot, and the engine can't breathe so it has no power. Get them to check the cats for throughflow on the hot side. Joe |

Runs a mile and then gets hot, maybe my blocked cat theory is the one to look at next. [A cheap way to check would be to cut out the one on the hot side, weld in a piece of pipe the correct diameter, and drive it. If it stays going well, then you have identified your problem. Buy a replacement cat for that side.] Joe |
Definitely
