Note! Compression testing should always be carried out at wide open throttle (WOT) and with the engine at operating temperature. Diagnostic
trouble codes (DTCs) will be stored because the engine speed (RPM) sensor and (where applicable) the camshaft position (CMP) sensor have
been disconnected.
Have an assistant hold the accelerator pedal (AP) depressed at wide open throttle (WOT) during the compression test.
The starter motor is activated with the ignition key.
The ignition must be switched off after each cylinder has been compression tested.
Note! It will no longer be possible to control the throttle if the ignition is on for longer than 2 minutes. The throttle function is controlled by the
control module.
