I have a 96 integra gsr. My check engine light is on. I checked the ecu and the check engine light flashed five times. I looked in my book it says I need to check my map sensor. Five flashs in my book give three different codes. First one, p0106 manifold absoulte pressure circuit range/performance problem. Sencond one, Manifold absoulte pressure higher than expected. Third one, manifold absoulte pressure lower than expected. I have an apexi VAFC, I checked all of the connections. I tried changing the senor. I checked for breaks and corrosion on the wires coming from the ecu to the MAP sensor. The check engine light came on shortly after I hit a bump at 10mph. Or I was just thinking it could me 41 which is O2 sensor heated sensor fault. I would appreciate the help.

 

Did you mess with the fuel adjustments on the vafc? if you adjust them past a certain extent, it will throw a code.

 

yes, I did. I didn't lean it out a lot. There is a different code for lean and rich. But I think it is just the O2 sensor because the O2 sensor looks a little beaten up becasuse of my aftermartket cat. The O2 sensor points down and my car is kind of low. So it has touched down quiet a few times. So I went to a muffler shop and got it fixed now I am looking around for a new O2 sensor so I will try this and see if this is it.
