What it means
The intake camshaft actuator park-lock circuit on bank 2 is below the expected electrical threshold. This indicates a low circuit condition, not necessarily a specific short or internal driver failure.
At a glance
- Usually lights the check-engine light
How it works
The bank 2 intake camshaft actuator park-lock circuit operates the solenoid that holds that intake phaser in its parked position when required. P25CE sets when the control module detects a circuit level below its expected threshold; the low condition can result from a grounded wire, a driver problem, or a poor connection.
Common causes
Most likely first.
- Control wire shorted to ground
- ECU low-side driver internally shorted
- Connector pins corroded - high contact resistance
Symptoms
- Check engine light on
- Power loss especially in mid-rpm range
- Possible rough idle or stalling
- Increased fuel consumption
How to diagnose it
- Record freeze-frame data and related actuator codes, including the conditions when the bank 2 intake circuit went low.
- Inspect the bank 2 intake park-lock connector and harness for corrosion, loose or damaged pins, chafing, or contact with ground.
- Check terminal fit and condition because corrosion or a poor connection can create an abnormal circuit reading.
- Measure the circuit at the solenoid and control-module connectors under the manufacturer's test conditions to narrow down where the low reading occurs.
- Isolate the solenoid and harness as specified, then test for a short to ground and verify solenoid and driver behavior against manufacturer specifications.
Common fixes
- Clean, secure, or repair corroded terminals at the bank 2 intake park-lock connector.
- Repair a bank 2 intake control wire shorted to ground.
- Replace the park-lock solenoid if it fails the manufacturer's electrical test.
- Repair the control-module driver only after ruling out the solenoid and wiring.
Can I keep driving?
If the engine runs normally, restrict driving to a cautious trip for diagnosis and avoid heavy acceleration. Stop in a safe place if rough running, stalling, or power loss occurs.
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.
