P2089 Cadillac 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 Cadillac 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 Cadillac?
- 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)

Frequently Asked Questions about P2089 Cadillac Code
1. What does the OBDII code P2089 mean on a Cadillac?
P2089 indicates that the Intake Camshaft Position Actuator Solenoid Valve Control Circuit on Bank 1 is experiencing a high voltage issue, which can affect camshaft timing.
2. What are the symptoms of the P2089 code on a Cadillac?
Common symptoms include rough idling, reduced engine performance, poor fuel economy, and possibly the illumination of the Check Engine Light.
3. What causes the P2089 code on a Cadillac?
The code can be caused by a faulty camshaft actuator solenoid, damaged wiring, loose electrical connections, or an issue with the engine control module (ECM).
4. Can I drive my Cadillac with the P2089 code?
Driving with the P2089 code is not recommended, as it can lead to further engine performance issues and potentially damage internal engine components over time.
5. How is the P2089 code diagnosed on a Cadillac?
A mechanic will typically use a scan tool to verify the code, inspect the camshaft actuator solenoid and its wiring, and check for proper voltage and resistance levels in the circuit.
6. How do I fix the P2089 code on my Cadillac?
Repairs may involve replacing the camshaft actuator solenoid, repairing or replacing damaged wiring, cleaning electrical connections, or reprogramming the ECM if necessary.
7. What does "Bank 1" mean in the context of the P2089 code?
Bank 1 refers to the side of the engine containing cylinder 1. On a V-type engine, it helps identify which side of the engine is affected.
8. What tools are needed to repair the P2089 code?
Basic tools include a multimeter to test voltage and resistance, a scan tool for diagnostics, and possibly wrenches and sockets to replace the solenoid.
9. How much does it cost to repair the P2089 code on a Cadillac?
Repair costs vary, but replacing a camshaft actuator solenoid typically ranges from $100 to $300, including parts and labor, depending on the model and location.
10. Can a dirty engine oil cause the P2089 code on a Cadillac?
Yes, dirty or low engine oil can restrict the solenoid's function, leading to this code. Regular oil changes can help prevent this issue.
