Code P2089 Chevrolet Description
Ignition voltage is supplied directly to the Camshaft Position Actuator Solenoid Valve. The ECM controls the solenoid valve by grounding the control circuit with a solid-state device called a driver. The driver is equipped with a feedback circuit that is pulled up to a voltage. The ECM can determine if the control circuit is open, shorted to the ground, or shorted to a voltage by monitoring the feedback voltage.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects an open solenoid circuit in the CMP actuator for greater than 1 second or a cumulative of 5 seconds when the solenoid is commanded OFF.
The ECM monitors the control circuit of the CMP actuator solenoid for electrical faults. The ECM can determine if a control circuit is shorted high. If the ECM detects a fault with the CMP actuator solenoid control, DTC P2089 will set.
What are the Possible Causes of the DTC P2089 Chevrolet?
- Faulty Intake Camshaft Position Actuator Solenoid Valve Bank 1
- Intake Camshaft Position Actuator Solenoid Valve Bank 1 harness is open or shorted
- Intake Camshaft Position Actuator Solenoid Valve Bank 1 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P2089 Chevrolet?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
