What it means
The control module detects an electrical fault in the Bank 2 exhaust valve control solenoid circuit. The code alone does not establish what the controlled exhaust valve does on a particular vehicle.
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
The bank 2 exhaust valve control solenoid is an electrical actuator in the system that controls exhaust-valve operation. The control module monitors its circuit and sets this code when it detects an electrical problem, but the code alone does not identify the controlled valve's function or the exact circuit failure.
Common causes
Most likely first.
- Solenoid coil failed
- Open or short in the wiring
- Loose or corroded connector
- Control module driver fault
Symptoms
- Check engine light on
- Rough running or hesitation
- Reduced engine performance
How to diagnose it
- Record freeze-frame data and scan for related exhaust-valve control codes to understand when the bank 2 circuit fault occurred.
- Inspect the bank 2 exhaust valve solenoid connector and harness for loose or corroded pins, broken wires, or damaged insulation.
- Use the manufacturer's wiring diagram to check the solenoid's power, ground, and control circuits for opens or shorts.
- Test the bank 2 solenoid coil and wiring continuity against the manufacturer's specification.
- If the solenoid and wiring pass, check the control-module driver and commanded operation using the manufacturer's procedure.
Common fixes
- Reconnect or clean the bank 2 exhaust solenoid connector and repair damaged terminals.
- Repair open or shorted bank 2 solenoid wiring.
- Replace the bank 2 exhaust valve control solenoid if it fails electrical testing.
- Repair a confirmed control-module driver fault after checking the circuit and solenoid.
Can I keep driving?
If the engine runs normally, limit driving to gentle trips and avoid heavy loads if hesitation or reduced performance appears. Stop if the engine runs roughly enough to affect safe control or power.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
