P000D

What it means

P000D means the engine control unit has detected that the 'B' camshaft on bank 2 is slow to move to the position it was commanded to. 'B' is usually the exhaust camshaft, but this depends on the engine. The unit compares the camshaft position sensor signal with the crankshaft signal and sees the variable valve timing adjustment arriving later than expected.

Symptoms

• Engine warning light on
• Rough or unstable idle
• Hesitation or reduced power
• Poor fuel economy
• Rattling or ticking from the timing drive area, particularly at start-up
• Engine running in a reduced-performance mode

Possible causes

• Low, dirty, degraded or incorrect-grade engine oil slowing the timing adjusterlikely
• Blocked or sticking oil control (variable valve timing) solenoid or its inlet filter screen on bank 2likely
• Wiring, connector or earth fault on the bank 2 solenoid or camshaft sensor circuitpossible
• Worn or sticking camshaft phaser (timing adjuster)possible
• Low oil pressure from a worn oil pump, blocked pickup or worn bearingspossible
• Stretched timing chain or incorrect timing correlation affecting the measured cam positionpossible
• Faulty camshaft position sensor or damaged reluctor wheel giving a poor signalrare

How to diagnose

1. Read all stored and pending codes and note the freeze frame data, including engine temperature, load and speed when the fault set.
2. Check the oil level and condition, and confirm the grade matches the manufacturer's specification; look for sludge, fuel dilution or an overdue service.
3. Inspect the wiring and connectors to the bank 2 oil control solenoid and camshaft sensor for damage, corrosion, oil contamination or chafing.
4. Check live data for the bank 2 'B' camshaft target against actual angle at idle and under light load, and look for lag or erratic movement.
5. Run the actuator test for the bank 2 solenoid if the scan tool supports it, and check the camshaft responds smoothly.
6. Test the solenoid resistance and supply and signal circuits against the manufacturer's figures, which vary by engine.
7. Remove the solenoid and inspect it and its filter screen for debris, sticking or damage.
8. Check oil pressure against specification, and check timing chain stretch and cam-to-crank correlation using the procedure for that engine.

How to fix

• Change the oil and filter to the correct grade and specification, and correct the oil level.
• Clean or replace the bank 2 oil control solenoid and its filter screen if blocked or faulty.
• Repair or replace damaged wiring, connectors or earth connections.
• Replace the camshaft phaser if it is worn, noisy or not holding or adjusting correctly.
• Replace a faulty camshaft position sensor or damaged reluctor wheel.
• Rectify low oil pressure or timing chain wear, and replace the chain, guides and tensioners as required.
