Hi Folks! New to , new to XJs in general, but not totally new to cars and wrenching.
Just bought my first XJ -
1999 Cherokee Classic, 4.0L, Auto.
I've started getting these errors together:
P0112 - Low Intake Air Input
P0117 - Low Engine Coolant Input
I've pulled the sensors, both spec in range for resistance, and when I probe the connector, I appear to have 5V across the pins. Also, the temp gauge will intermittently zoom up to 260+, then come right back to the bottom - sometimes in the first 5 minutes of turning the engine on.
This screams an intermittent issue - maybe grounding? As I'm new to these, is there an obvious place to start? Frustrated from a night wrenching on it, but next steps that I can think of are pulling ECU connectors and cleaning, and working my way out.
Anything that would help narrow down the search appreciated. Thanks all!
