I've got my diypnp running decently well now, but i think the IAT is getting some weird readings.
First of all IAT sensor = MAT reading, correct?
Watching the MAT gauge in the diagnostics screen it either:
A.) stays at 0 degrees and "blips" up 30 degrees and goes back to 0 degrees
B.) reads 70 degrees constantly
If i recalibrate as a GM sensor, it seems to randomly pick A/B above.
This is how i have it wired:
I verified that my pigtail connections are good.
Should i test at the ECU connector next? or should I check my MS board? I have the IAT diode installed in the pullup. I'm just unsure what should be my focus next. I'm thinking of retouching all the solder connections on the IAT stuff just to be sure they are solid.
