Map Sensor Fault/pcm? Anyone?

1 post in this topic

Im getting some readings from my MAP/MAF sensor(both changed for new ones)

The MAP sensor coming from intercooler(drivers side on pipe under headlight area) is only reading 0.03volts & doesnt budge,even after replacing. also both maf/map sensors seem to read erratic when driving along at steady speed ieMAP reads for example: 0.1, 8.0 2.9

same with MAF but not SO erratic.

My EGR valve doesnt seem to open much either. vacuum appears to be working ok.

On the snap-on,it seems to have a map readinng in Kpa,so cant tell whether its 1bar or not.

Anyone have any experiences like this before? Im wondering if it could be a faulty/corrupt PCM/ECU.

Anyone have any advice? Im stumped.
