2002 Honda Accord P0505, P0113, P1166, P1486, P108 - Car Stalls and Loss of Power Diagnosis
Last night, while driving, my 2002 Honda Accord suddenly lost power. The engine began to bog down as if it were out of gas, then shut off completely. I assumed the issue was low fuel, so I filled up with gas—my gas light was on, but the problem persisted. After restarting, the car started but immediately bogs down and dies again. A tow was arranged, and upon arriving the next morning, the vehicle started normally and drove fine. However, using an OBD2 scanner, I retrieved several diagnostic trouble codes: P0505, P0113, P1166, P1480, and P108. I need to prioritize which of these codes are most likely related to the symptoms—specifically engine stalling and loss of power—so I can address them first before my next work shift. As a non-professional with limited funds until next week, I'm looking for clear guidance on what each code means and which one should be fixed first. Can anyone help me understand the root causes and recommend the priority order for repairs?
Start here: Potential causes of a P0108 code: - Faulty Mass Airflow (MAP) sensor - Vacuum leak in the supply line to the MAP sensor - Engine vacuum leaks - Short circuit on the signal wire to the Powertrain Control Module (PCM) - Short circuit on the reference voltage wire from the PCM - Open ground circuit at the MAP sensor - Worn engine components causing reduced vacuum Read more: https://www.autozone.com/repair-info/p0108 Potential causes of a P0505 code: - Damaged Idle Air Control (IAC) motor connector (check for physical damage or moisture) - One or more IAC circuits open or shorted to ground - One or more IAC circuits shorted to power voltage - Failed IAC valve - Faulty Powertrain Control Module (PCM) Read more: https://www.autozone.com/repair-info/p0505 Note: P0505 is strongly linked to stalling and loss of idle, which matches your symptoms. Addressing this code first may resolve the immediate issue. P1166 relates to oxygen sensor performance and may affect fuel efficiency but not directly cause stalling. P0113 indicates a low intake air temperature sensor reading—could be related to vacuum issues or sensor failure. P1486 is typically associated with EGR system faults, which are less likely to cause sudden stalling. Prioritize P0505 and P0113 for immediate repair.
