2004 Jeep Grand Cherokee P0505 Code: IAC Motor Replacement Failed - Fix and Diagnosis
I recently encountered a P0505 code on my 2004 Jeep Grand Cherokee. I replaced the Idle Air Control (IAC) motor, which initially resolved the issue—my check engine light turned off and the vehicle ran smoothly for 12 to 15 miles. However, after returning home, I shut down the vehicle and restarted it; the check engine light reappeared with the P050
