D

Damaged harness – Inspect the wiring harness for
damage; shorts to ground, shorts to battery positive,
and open circuits.

D

Vacuum leak – Check for a condition that causes a
vacuum leak, such as disconnected or damaged
hoses, leaks at EGR valve and EGR pipe to intake
manifold, leak at the throttle body, a faulty or incorrectly
installed PCV valve, leaks at the intake manifold, etc.

D

Throttle body – Check for sticking throttle plate. Also
inspect the IAC passage for deposits or objects which

will not allow the IAC pintle to fully extend or properly
seat.

If Diagnostic Trouble Code P0507 cannot be duplicated,
reviewing the Failure Records vehicle mileage since the
diagnostic test last failed may help determine how often
the condition that caused the Diagnostic Trouble Code to
be set occurs. This may assist in diagnosing the
condition.

1. Start the engine.
2. Turn all accessories OFF (A/C, rear defroster, etc.)
3. Using a Tech 2, command RPM up to 1500, down to

500, and then up to 1500 while monitoring ”Engine
Speed” on the Tech 2.

Does the ”Engine Speed” remain within the specified
value of ”Desired Idle” for each RPM command?

X22SE 2.2L ENGINE DRIVEABILITY AND EMISSION

DIAGNOSTIC TROUBLE CODE (DTC) P0563 SYSTEM VOLTAGE HIGH

D06RX127

Circuit Description

The engine control module (ECM) monitors the system
voltage on the ignition feed terminals to the ECM. A
system voltage Diagnostic Trouble Code will set
whenever the voltage is above a calibrated value.  DTC
P0563 is a type A code.

Conditions for Setting the DTC

D

Ignition ON.

D

System voltage is above 16.

Action Taken When the DTC Sets

D

The ECM will not illuminate the malfunction indicator
lamp (MIL) for the first time the malfunction is detected.

D

The ECM will store as Failure Records conditions
which were present when the Diagnostic Trouble Code
was set. This information will not be stored as Freeze
Frame data.

Conditions for Clearing the MIL/DTC

D

A history Diagnostic Trouble Code P0563 will clear
after 40 consecutive warm–up cycles have occurred
without a fault.

D

Diagnostic Trouble Code P0563 can be cleared by
using the Scan Tool’s ”Clear Info” function.

Diagnostic Aids

Check for a faulty charging system components.
