Hey Guys,
1991 2.5L MPFI,
Ran the Jeep for about 30 miles and on the last mile I got a Check Engine Light. The Jeep ran normally during the CEL, and also was idling correctly, no noticeable hesitation or sputtering. I noticed that during the CEL activation that my oil pressure gauge pegged all the way to 80psi, probably a coincidence lol.
I checked the ECM code readout and got code 23, which I interpreted as "Intake air temperature signal out of range". Is that the sensor on the intake manifold? Or is it associated with the IAC? Just need a point in the right direction, thank you!
