AEM constant 5v to MAP and O2
My AEM ECU v2 reads 5.04-5.06 volts for my O2 and MAP when I hook my laptop up to the car.
I put paint thinner on a rag and wrapped my O2 sensor in it and my AFR gauge showed it going from full lean to slowly rich like it should but my ECU was still getting 5v and didn't seem affected by the test.
this didn't just suddenly happen, this is the first time the car has been had an engine in it in a year and everything is hooked up right, just the MAP and O2 are reading bad so the car won't start.
Is my ECU bad?
