What Does P2659 Mean?
The PCM has detected an abnormally high voltage in the control circuit for the Bank 2 rocker arm actuator. This suggests a short to power, open circuit, or resistance issue preventing proper actuator control.
Common Causes
35%
Shorted to voltage wiring or pinched harness contacting power source
25%
Open circuit in actuator solenoid or control circuit
20%
Damaged or corroded connector with high resistance or open
15%
Failed rocker arm actuator with open internal coil
5%
PCM driver circuit failure or internal fault
Diagnostic Steps
1
Step 1: Disconnect actuator and measure voltage at harness connector; should show 0V with key on, engine off
2
Step 2: Check for short to voltage by measuring voltage on control wire with actuator disconnected and PCM connected
3
Step 3: Test actuator solenoid resistance; infinite resistance indicates open coil
4
Step 4: Inspect connector terminals for corrosion, bent pins, or pushed-back terminals
5
Step 5: Check wiring harness routing for contact with hot components or voltage sources
Estimated Repair Cost
$150 - $750
Parts + labor, varies by vehicle and location
The PCM has detected an abnormally high voltage in the control circuit for the Bank 2 rocker arm actuator. This suggests a short to power, open circuit, or resistance issue preventing proper actuator control.
The most common cause of P2659 (A Rocker Arm Actuator Control Circuit High Bank 2) is: Shorted to voltage wiring or pinched harness contacting power source
Typical repair costs for P2659 range from $150 to $750, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive with reduced performance and fuel economy. No immediate safety concerns but should be repaired to restore proper engine operation.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2659 to identify the root cause.
