Is it safe to drive with this code?

In many cases, continuing to drive may worsen the problem and risk serious internal engine damage—particularly if the issue stems from a stretched timing chain that could jump teeth. If you notice rough running, stalling, or loss of power, it's advisable to minimise driving and arrange prompt inspection (see our site disclaimer for full guidance).

It may do, depending on whether the malfunction indicator lamp is illuminated at the time of test. Emissions readings can also be affected by timing issues. For detailed MOT implications, see our disclaimer.

Roughly how much does it cost to fix?

Diagnostic fees typically fall in the low two-figure range at an independent garage. If the fix is straightforward—such as a sensor replacement or an ECM software recalibration—the total may be low to mid three-figure. However, timing-chain replacement, tensioner renewal, or reluctor-ring work can reach high three-figure to four-figure sums, particularly at a franchised dealer. Labour is often the largest component because of the stripdown involved.

Can low or dirty oil cause this code?

Yes, in vehicles with variable valve timing; insufficient or degraded oil can prevent the camshaft phaser from operating correctly, leading to timing discrepancies. Regular oil changes using the manufacturer-recommended grade may help prevent this fault.

Powertrain

Engine Position System Performance Bank 2

The engine control module has detected that the camshaft and crankshaft on bank 2 are not properly synchronised, which can affect engine timing and performance.

ⓘ Information only. This page provides general educational information about fault code P0009. 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 P0009 mean?

P0009 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Engine Position System Performance 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 P0009 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 P0009.

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
