Hello,
I keep getting this fault code appear but only after wot acceleration. I have changed to the revision D Diverter valve and have fitted a catch can to replace the PCV. I also replaced the N75 valve and still get the code. The car has been pressure tested and all is okay. The fault code does not appear when I run the stock map but does when I run the stage 1 map. However it still appears when running stock parts with the stage 1 map. I dont believe it is the Shark map as other cars run the same map and run fine. When I get the fault code the engine light does not come on so it is as if the ECU is seeing that it is not making pressure for a millisecond, enough to trigger the fault code and then it is making the required boost pressure.
I was thinking about this and did some research about the MAP sensor. I was reading that if there is a MAP Sensor problem it would cause the engine to run richer than normal. I cast my mind back to when I took my car to Rtech and they commented that the engine ran rich when under WOT. I was wondering if the MAP sensor was slighlty faulty and not giving correct readings (albeit within tolerance) if it could indeed trigger the fault code.
Any ideas from anyone?
Cheers Matt
