Checking idle RPM under detecting condition, if the real idle speed is higher than desired idle speed by 200 RPM over 15 sec., ECM/PCM sets P0507.
Item | Detecting Condition | Possible Cause | |
DTC Strategy | Case 1 |
•
Engine speed is below the target while ISC torque is around the maximum | 1. Intake system for blockage |
Case 2 |
•
Fuel cut-off during stand-still and idle condition | ||
EnableConditions |
