Circuit/System Verification
1. Observe the DTC information with a scan tool.
瀚慖f there are any throttle actuator control (TAC), throttle position (TP) sensor, accelerator pedal position (APP) sensor, or fuel rail pressure
(FRP) regulator DTCs set, refer to Diagnostic Trouble Code (DTC) List - Vehicle (See: Diagnostic Trouble Code
Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).
2. Operate the engine within the conditions for running the DTCs for 1 minute. DTC P0506, P0507, or P050A should not set.
3. 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
Engine operating, command the engine speed up to 1,400 RPM, down to 600 RPM, up to 1,400 RPM, and then exit using the scan tool. The engine
speed should steadily increase and decrease as commanded.
If the idle does not increase or decrease steadily, verify that none of the following conditions is present:
* Vacuum leaks
* The throttle valve for the correct operation-A throttle valve that does not close correctly sets this DTC.
* Restricted air intake system
* The throttle body for damage and/or tampering
* Incorrect or malfunctioning PCV system
* Excess deposits in the throttle body
* A parasitic load on the engine-For example, a transmission condition, a belt driven accessory condition
瀚慠epair the condition as necessary.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
P0513
DTC P0513
Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System
Check - Vehicle) prior to using this diagnostic procedure.
