What it means

P002F means the engine control unit has detected a high voltage state on the control circuit for the Bank 2 'B' camshaft profile actuator 'A'. This is the system that changes cam lift or profile. The unit sets the code when the circuit voltage is higher than commanded, which points to a short to voltage, a wiring fault or a failed driver or actuator. Which camshaft and actuator are 'B' and 'A' depends on the engine, so check the layout for your model.

Symptoms

Engine warning light on
Reduced power or the engine running in a limited performance mode
Rough idle or uneven running
Poor fuel economy
Hesitation or flat spots under load
Possible extra valve train noise or a change in engine note

Possible causes

Faulty camshaft profile actuator (solenoid or internal coil fault)likely
Wiring fault on the control circuit, such as a short to voltage or chafed insulationlikely
Damaged, corroded or oil-contaminated connector or terminals at the actuatorlikely
Poor or incorrect supply voltage or a bad earth affecting the circuitpossible
Low, dirty or incorrect engine oil affecting actuator operation and the control responsepossible
Fault in the engine control unit output driverrare
Outdated control unit software where the manufacturer has issued a known fix for this faultrare

How to diagnose

Read all stored and pending codes and note the freeze frame data, including engine speed, load, temperature and battery voltage
Check for related codes such as cam timing, cam position sensor or other actuator circuit faults, and for other Bank 2 faults
Check the engine oil level, condition and specification, as dirty or wrong oil can affect the system
Inspect the actuator wiring and connector on Bank 2 for chafing, heat damage, oil ingress, bent pins and corrosion
Check the actuator resistance against the manufacturer's specification, and test the actuator for shorts to ground and to supply
With the ignition on, check the supply voltage and earth at the connector, and check the control wire for a short to voltage
Back-probe the control circuit and watch the signal with an oscilloscope or a suitable live data tool while the actuator is commanded
Check for manufacturer technical bulletins and software updates for your model before condemning the control unit

How to fix

Repair or replace damaged wiring and fix any short to voltage on the control circuit
Clean or replace the connector and terminals if they are corroded, loose or contaminated with oil
Replace the Bank 2 camshaft profile actuator if its resistance or operation is out of specification
Correct supply or earth faults found during testing
Change the oil and filter to the correct specification if the oil is dirty, low or incorrect
Repair or replace the engine control unit only after the wiring and actuator are proven good, and apply a manufacturer calibration update only where a known fault is documented

Can I keep driving?

Medium severity

The car can usually be driven carefully for a short time, but it may run in a reduced performance mode and the fault may get worse. Have it diagnosed soon, and avoid heavy loads or high revs until it is fixed.
