Circuit/System Verification
1. Ignition ON, observe the DTC information with a scan tool. Verify there are no other DTCs set.
瀚慖f a DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble
Code (DTC) List - Vehicle).
2. Idle the engine at the normal operating temperature. Compare the Desired Idle Speed to the actual Engine Speed with a scan tool. The actual
Engine Speed should not be less than 100 RPM of the Desired Idle Speed or 200 RPM greater than the Desired Idle Speed.
3. Allow the engine to idle within the Conditions for Running the DTC. DTCs P0506 or P0507 should not set.
