Code P0505 1998 Toyota Camry Description
The ECM regulates the idle speed by opening and closing the throttle valve using the ETCS. The ECM concludes that the idle speed control ECM function is malfunctioning and set the Diagnostic Trouble Code (DTC) if:
1. The actual idle RPM varies more than the specified amount five times or more during a drive cycle
2. The learning value of the idle speed control remains at the maximum or minimum five times or more during a drive cycle.
Example: If the actual idle RPM varies from the target idle RPM by more than 200* rpm five times during a drive cycle, the ECM will turn on the MIL and will set a DTC.
What are the Possible Causes of the DTC P0505 1998 Toyota Camry?
- Idle Air Control (IAC) Valve is stuck or closed
- Faulty Idle Air Control Valve
- Idle Air Control Valve harness is open or shorted
