P0506

The actual idle speed is approximately 90 RPM lower than the desired idle speed.

P0507

The actual idle speed is approximately 180 RPM greater than the desired idle speed.

Action Taken When the DTC Sets

DTCs P0506 and P0507 are Type B DTCs.

Conditions for Clearing the MIL/DTC

DTCs P0506 and P0507 are Type B DTCs.

Diagnostic Aids

* A stalling condition can cause DTC P0506 to set.

* An intermittent vehicle speed sensor (VSS) signal can cause DTC P0507 to set.

* An intermittent clutch pedal position sensor signal, if equipped, can cause DTC P0506 to set.

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) for further diagnosis.

Note: The engine must run for greater than 60 s, then idle at a steady state for an additional 10 s before comparing the actual and desired

engine speed parameters.

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. DTC P0506 or P0507 should not set.

4. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

Verify none of the following conditions exist:
