What it means
Generic electrical fault on the intake-valve control solenoid for bank 2 (used to switch valve lift, deactivation or VVL profiles).
At a glance
- Usually lights the check-engine light
- Affects emissions; the car can fail an emissions test
How it works
The bank 2 intake valve control solenoid operates a mechanism that changes intake-valve operation, such as valve lift or deactivation, where fitted. The control module monitors the solenoid circuit and sets this code when it detects an electrical fault, without specifying whether the circuit is open, shorted, or the solenoid has failed.
Common causes
Most likely first.
- Solenoid coil failed
- Open or short in the solenoid wiring
- Loose or corroded connector
- Control module driver fault
Symptoms
- Check engine light on
- Rough idle or engine hesitation
- Reduced power or fuel economy
How to diagnose it
- Record freeze-frame data and scan for other valve-control codes to identify when the bank 2 intake solenoid fault occurred.
- Inspect the bank 2 intake valve control solenoid connector and harness for looseness, corrosion, broken wires, or damaged insulation.
- Use the manufacturer's wiring diagram to check the bank 2 solenoid's power, ground, and control paths for opens or shorts.
- Measure the bank 2 solenoid coil and circuit continuity against the manufacturer's specification.
- If the solenoid and wiring pass, check commanded operation and the control-module driver using the manufacturer's procedure.
Common fixes
- Reconnect or clean the bank 2 intake solenoid connector and repair damaged terminals.
- Repair an open or short in the bank 2 solenoid wiring.
- Replace the bank 2 intake valve control solenoid if it fails coil testing.
- Repair a confirmed control-module driver fault after checking the circuit and solenoid.
Can I keep driving?
Gentle driving may be possible if the engine remains stable, but avoid hard acceleration if hesitation or reduced power occurs. Continued operation with incorrect bank 2 intake-valve control can worsen drivability and fuel economy.
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.
