CEL light
Well about 6 months ago I installed a vibrant header and a magnaflow high flow cat on my b16. I drove it without any problems for about 2 weeks before I got the cel light on. The code is P0108 Manifold absolute pressure /barmetric pressure circuit high . Now in the past on a different car I had issues with the cel and a high flow cat but the code came up that there was an issue with emissions (The cat specifically). This time its a map sensor problem which I believe deals with fuel, intake manifold pressure,rpm and barometric .
Basically my question is more than likely is it the cat or the header that cause the code or did it go on for a different reason , where should I start looking ? Any advice would be great ! |
The cat has nothing to do with map sensor throwing a code. Just a coincidence.
If you can manage to take the 2 Philips screws out without stripping them you could clean the sensor and seal it tight on there. |
MAP sensor check:
Key on engine off: check for 5V reference signal and ECM ground. The remaining wire on the harness connector is for signal. If you have power and ground, replace the sensor. You can't clean a MAP sensor, so don't waste your time. Replace it. |
Checked wire harness for power and got 5 v. Picked up new sensor for $45 installed and removed logged code... cel gone ! :)
Turns out it was really just was a coincidence Thanks for your help |
Well after replacing the map sensor Friday afternoon the car has been running fantasic! I was on my way home tonight and the f****ing cel light just came back on :doh: :mad:
I let a friend borrow my scanner so I will have to wait till tomorrow afternoon to see what code popped up. Chances are its the same code (P0108) , anyone else have any suggestions if this is the case??? |
