What Does P2089 Mean?
The variable valve timing (VVT) system on Bank 1 intake camshaft is receiving excessive voltage. The ECM detects the control circuit voltage is higher than expected when commanding the camshaft position actuator.
Common Causes
40%
Open circuit in VVT solenoid ground or control wire
30%
Failed VVT solenoid with internal open circuit
20%
Damaged or disconnected connector at VVT solenoid
10%
ECM driver circuit failure
Diagnostic Steps
1
Step 1: Inspect VVT solenoid connector for proper connection and terminal integrity
2
Step 2: Measure resistance of VVT solenoid (typically 6-12 ohms); infinite resistance indicates open circuit
3
Step 3: Check continuity of control wire from ECM to VVT solenoid
4
Step 4: Verify ground circuit continuity between solenoid and ECM (should be less than 1 ohm)
5
Step 5: If circuits test good, replace VVT solenoid and retest system
Estimated Repair Cost
$150 - $600
Parts + labor, varies by vehicle and location
The variable valve timing (VVT) system on Bank 1 intake camshaft is receiving excessive voltage. The ECM detects the control circuit voltage is higher than expected when commanding the camshaft position actuator.
The most common cause of P2089 (A Camshaft Position Actuator Control Circuit High Bank 1) is: Open circuit in VVT solenoid ground or control wire
Typical repair costs for P2089 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but engine performance, fuel economy, and idle quality will be affected. May cause rough idle, reduced power, or increased emissions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2089 to identify the root cause.
