MAP sensor issue

[Mac0892]

So I had my car (bf mk2 xr6t) in at work last thursday and put it on the scan tool during lunch and went for a drive since I have been looking for an issue that has been causing it to run rich and chug fuel. I threw a new o2 sensor at it and that seems to have stopped it from popping through the exhaust, but it still runs fair rich. using the scanner whilst driving, I monitored the intake and fuel systems. at idle, my map sensor was reading around 14.9psi (not sure on conversion but I think it is a shade over 1bar) and under full boost, it read that I was running 31psi through a stock turbo setup.

 

Is there a way to test the map sensor without having to replace it with a known working one or should I just throw a new one in an see how it goes from there?

Those figures are normal. Tmap reads absolute pressure so atmo is around 14.68  psi and boost is atmo plus boost pressure so in your case 15 to 16 psi boost plus atmo = 31ish at full load.

They're reading normal? Well that blows my theory out the water :/

Going to have to start checking everything else now. Thanks for the info ralph.

 

I checked codes this morning using the obd2 and torque. Had a p1131 code and a p0302 (I think). So o2 sensor reading lean and knock sensor 2 issue. This car is developing a demon
