Re: Changing cam-shaft position sensor? 147
I dissagree and think the sensor is working. A decent disgnostic specialist could hook up a scope and show a wave form, or not, in minutes. I'm sure the engine wouldn't run if the sensor was gubbed because it wouldn't know which of the cylinder pair was on power stroke rather than exhaust stroke. I think the system has simply detected an anomally with the timing and thrown an error code.
I think the exhaust cam timing is out, or both. If the tensioner was changed before, then, with care, you could get away with simply resetting the timing. The belt will likely have to come off the top 2 pulleys for this, and it is perhaps inadviseable to risk a used belt.
I also think the TS coolant pumps are better than people give credit for. My sister's 155 is on 172k with original pump. However, in your case, a quick look gives piece of mind, but that means a coolant change.
