HI Folks: I have a 2001 JDM WRX (AVCS) that I Time Attack and am located in Nova Scotia Canada. I am posting to this group as my car has a ot more in common with UK Subaru's than the North American versions. I am hoping someone with AVCS experience can help me .
For the past few months I have had some hesitation/misfire issues under load and generally when the engine warms up. The car otherwise runs quite well This problem has been hard to track down. The other day I put in a Tomei turbo inlet as the OEM one had a slight rip resulting in a vacuum leak that I thought might be the cause of the problem. Once installed, I noticed a check engine light but took the car for a short drive to see if the hesitation was fixed. It still experienced the hesitation issue and then, abruptly stopped running. It crank over but would not restart. The CEL indicated a camshaft sensor Bank 2 problem (P0340). I also had a weird code (B3A02) that I could not track down. I had it towed to my Subaru performance shop. They installed a new crankshaft sensor which seems to have dealt with the hesitation problem (even though it never threw a crankshaft sensor code) and also installed a new camshaft sensor. It then ran nicely with no hesitation BUT the has no AVCS even with the new AVCS camshaft sensor . They spent a lot of time (and I spent a lot of $$$) trying to track down the issue. I am no longer getting a cam shaft sensor code but the CEL stays on and the B3A02 code persists and can not be erased. I checked all the Bank 2 AVCS wiring as well as did a resistance check on the sensor. The shop thought that I may be experiencing a wiring issue that I created when I installed the new turbo inlet??
Anyways, this is the short version of a long story. I am wondering perhaps if a broken wire to the AVCS solenoid would create the problem? I am at a loss and would really like to get the AVCS back. It appears to me that the AVCS problem occurring immediately after putting the new turbo inlet in is a bit too much of a coincidence.
Thanks for any suggestions!!
