Is it safe to drive with this code?

Driving safety depends on symptoms; if the engine is misfiring, stalling, or lacking power significantly, continued driving may risk further internal damage or leave you stranded. If symptoms are mild, limit use and arrange diagnosis promptly—see our disclaimer for further guidance.

This code may affect your MOT—what matters is whether the malfunction indicator lamp (MIL) is illuminated at the time of the test. If the light is on, that's typically a fail. Underlying timing or emissions faults may also be detected during the visual or emissions portions of the test. See our MOT disclaimer.

Roughly how much does it cost to fix?

Repair costs vary widely depending on the root cause. Replacing a camshaft sensor or solenoid at an independent garage typically sits in the low-to-mid three-figure range, whilst timing chain replacement or more involved internal work can reach mid-to-high three-figure sums or beyond. Main dealers often charge 30–50% more. Diagnostic time (often £50–£100) is essential before committing to parts replacement.

Can dirty oil cause this code?

Yes—contaminated, old, or incorrect-viscosity oil can interfere with the hydraulic operation of variable valve timing components, leading to sluggish actuator response or circuit faults. Regular oil changes using manufacturer-specified grades are important preventive measures for camshaft-related codes.

P001D

Powertrain

A Camshaft Profile Control Circuit/Open Bank 2

The engine control module has detected an open circuit in the camshaft profile control system for the intake camshaft on Bank 2, which typically affects variable valve timing operation.

ⓘ Information only. This page provides general educational information about fault code P001D. We do not assess the urgency or safety implications of any specific fault. That requires in-person diagnosis by a qualified mechanic. Full terms.

Recommended next steps

Whether a fault is urgent, drivable, or routine depends entirely on the cause on a specific vehicle, and that can only be determined by a qualified mechanic with diagnostic equipment. If a warning light is illuminated, the most reliable next step is professional diagnosis.

What does P001D mean?

P001D is a Powertrain (engine, transmission, fuel system) fault code. It indicates: A Camshaft Profile Control Circuit/Open Bank 2.

This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.

About Timing codes

Timing codes relate to the variable valve timing (VVT) system, cam position, crank position, or the correlation between them. On engines prone to timing chain stretch (BMW N47, Ford EcoBoost, VAG TFSI), these codes often signal a stretched chain rather than a sensor fault.

What we know about P001D specifically

We record the SAE J2012 standardised definition and the system this code belongs to, but we have not yet published detailed driver-reported symptoms, common causes, or step-by-step diagnostic guidance for P001D.

Rather than invent that information by generating generic content from a template, we leave it out. For specific guidance, the most reliable sources are:

•your vehicle's own service manual or manufacturer-specific technical bulletins
•a qualified mechanic with a manufacturer-level diagnostic tool
•a marque specialist familiar with your make and model
