Question about 2001 Jeep Grand Cherokee
It idles high, then low. I have seven codes that come up. 4 of the code are oxygen sensor, I know but I have three I can't figure out why they are coming up. The 4 oxygen sensor codes are p0136, p0132, p0152, and p0138. The other codes are p0031 ho25 heater control, p0051 ho25 heater control, and p1499 hydraulic fan solenoid ckt. What could be the problem? please help!!!!
Hi there, do you get water from the air conditioning unit entering the passenger foot well, if so then perhaps water is dripping onto the electrics below and causing these problems (blocked evaporator unit) alternatively, get jeep to reset your system (2 minute job) and this should work, keep an eye on it as the first new code that appears should be the problem area, hope this helps
