Apparrently the "fix" cost tens of thousands to diagnose & r&d.

Think it was on some MRT related flyer or something.

Considering you don't hear of many of these AVCS problems and it costs apparently $400ish or so to "fix", I would be hitting Subaru up for a warranty claim. Mentioning that its a proven problem identified by MRT !!!

tuna 28-09-2007 02:03 PM

pm me now with all the detail,
what state is the car in etc

tuna 28-09-2007 02:09 PM

btw, cam/crank sensors are not the same as the avcs sensors,
if your car starts, dont bother playing with the cam/crank sensors.

the avcs sensors are at the rear of the heads next to the cam covers.

whether they are connected or not (or even if the solinoid is d/c), the AVCS if theres a problem will stay on 0 degrees advance, even under no oil pressure.

although i dont know what detail you can get out of the stock ecu, but on motec you can log the duty of the solinoid to at least see what its trying to do, if the duty is up and no difference in the results, then its definately an oil related issue.

personally i think the MRT issue is to do with people using the wrong types of oils to start with, playing with banjos and what not shouldnt make a hell of a lot of difference without masking a true problem.

Yeah no probs if you can clear a bit of space in your Inbox.

Cheers :)

Rexy03,
So after all that its safe to change around your cam/crank sensors, just don't swap in ones off the 06/07 GT/WRX/STi's.

If your WRX then refuses to start after the swap around it will be the sensor positioned behind the crankshaft pulley thats stuffed. :)[/QUOTE]

Ok now im getting confused ?????

I pulled the passenger side cam sensor and crank sensors out and found they are a bit different in construction at the probe/sensor end and have different numbers on them they are the same size though . so i didnt swap them
Now after reading the previous comments im a little confused as what i need to do ???

WRXTASY are you saying that if i put a dud cam sensor on the crank the engine wont start.

TUNA if my car starts as is then the cam/crank sensors are OK

tuna 28-09-2007 02:34 PM

clarified: AVCS is independant of starting the car.

car does start = cam/crank ok.
car not start = either cam / crank sensor, or CRIP not correct.
