Lack of Power, Hesitation, or Cut Out

WARNING: This page is about a different variant/trim than selected.

Inspect the engine electrical system for correct operation. Refer to Symptoms - Engine Electrical .
Verify that each injector harness is connected to the correct injector.
Inspect the MAF sensor for obstruction, contamination, and damage. Refer to Mass Airflow Sensor with Intake Air Temperature Sensor Replacement .

NOTE: The following actions may need to be repeated in order to verify an intermittent intake or exhaust camshaft actuator condition.

Engine warm and idling, verify the correct operation of the camshaft actuator system. Command the intake and exhaust camshaft actuators from 0 degrees to 25 degrees and back to zero while observing the scan tool Int. CMP Variance and Exh. CMP Variance parameters. Each parameter would be less than 2 degrees in each of the commanded states.
- If any of the parameters is greater than 2 degrees, inspect the suspect camshaft actuator and camshaft actuator solenoid valve and valve bore for contamination, obstruction, and damage. Refer to Camshaft Position Actuator Solenoid Valve Replacement and Camshaft Actuator System Description .
