What it means
P002D means the engine control unit has detected an open circuit or a control circuit fault on the 'A' camshaft profile actuator for the 'B' camshaft on Bank 2. The 'B' camshaft is usually the exhaust camshaft, but the exact layout depends on the engine. The control unit monitors the actuator's driver circuit and sets the code when the voltage or current does not match what it commanded, which suggests a broken wire, poor connection or failed actuator.
Symptoms
- Engine warning light on
- Reduced power or flat feel, especially at higher revs
- Rough idle or uneven running
- Poor fuel economy
- Engine may enter limp mode with limited revs or power
- Possible hesitation or hard starting
Possible causes
- Faulty camshaft profile actuator or solenoid with an open-circuit coil on Bank 2likely
- Damaged, chafed or corroded wiring between the actuator and the control unitlikely
- Loose, corroded or contaminated connector at the actuator or control unitlikely
- Oil leaking down the harness into the actuator connector, causing a poor connection or shortpossible
- Low or poor-quality engine oil, or blocked oil passages affecting the profile control system (usually sets related performance codes, but can add to the fault)possible
- Faulty engine control unit driver circuitrare
How to diagnose
- Read all stored codes and freeze frame data to see the conditions when the fault set, and check for related camshaft or oil pressure codes
- Check the engine oil level and condition, as profile control systems rely on clean oil at the correct level
- Visually inspect the Bank 2 actuator, its connector and the harness for oil contamination, chafing, heat damage or corrosion
- Disconnect the connector and check the pins for corrosion, spread terminals or moisture, and check the seal
- Measure the actuator coil resistance and compare it with the manufacturer's specification for that engine
- Check the supply and control wires for continuity, short to earth and short to supply, using the wiring diagram for the model
- With the connector fitted, check that the control unit drives the actuator when commanded (a scan tool actuator test is useful if the model supports it)
- Clear the code and road test to confirm whether the fault returns
How to fix
- Replace the faulty Bank 2 camshaft profile actuator or solenoid if its resistance is out of specification or it is open circuit
- Repair or replace damaged wiring and fit new terminals or connector sections as needed
- Clean and secure the connector, replacing it if the pins or seal are damaged
- Fix the source of any oil leak into the harness, and replace the contaminated harness section
- Change the engine oil and filter to the correct grade and level if oil condition is a contributing factor
- Diagnose and, only if proven faulty, repair or replace the control unit
Can I keep driving?
The car can usually be driven for a short time, but power may be reduced and the engine could go into limp mode. Get it checked soon, as running with the fault may affect performance and could cause further problems.
