P2089 2015 GMC Sierra Code - Intake Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Bank 1
Quick Answer
The Camshaft Position (CMP) actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. Common causes include 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. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2089 2015 GMC Sierra 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 2015 GMC Sierra?
- 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 2015 GMC Sierra?
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?
Labor: 1.0
To diagnose the P2089 2015 GMC Sierra code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
