Circuit/System Verification
1. Observe the DTC information with a scan tool.
➢ If there are any throttle actuator control (TAC),
throttle position (TP) sensor, or accelerator pedal
position (APP) sensor DTCs set, refer to
"Diagnostic Trouble Code (DTC) List - Vehicle
Diagnostic Information: ".
2. Operate the engine within the conditions for running
the DTCs for 1 minute. DTC P0506, P0507, or
P050A should not set.
3. If the vehicle passes the Circuit/System Verification
test, you may also operate the vehicle within the
conditions that are captured in the Freeze Frame/
Failure Records List.
Engine General Information and Diagnosis:
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 one of the following conditions is not
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 valve
• Excess deposits in the throttle body
• A parasitic load on the engine—For example, a
transmission condition, a belt driven accessory
condition
➢ Repair the condition as necessary.

DTC Descriptor
DTC P0560: System Voltage
Circuit/System Description
The engine control module (ECM) monitors the system
voltage to ensure that the voltage stays within the proper
range. Damage to components and incorrect data may
occur when the voltage is out of range.
Conditions for Running the DTC
• The vehicle speed is below 40 km/h(25 mph).
• The system voltage is below 11 volts or above 16
volts.
• Engine speed is above 1,500 RPM.
Conditions for Setting the DTC
The ECM detects a system voltage out of range for 2
seconds.
