Is it safe to drive with this code?

Continued driving is not advisable, as the fault can cause stalling in traffic or prevent the engine from starting when needed. Over time, incorrect timing signals may trigger misfires and potentially damage the catalytic converter or other components. See our site disclaimer for full guidance.

P0368 itself does not automatically fail an MOT, but if the malfunction indicator lamp (check engine light) is illuminated at the time of test, that can result in a fail under emissions regulations. For detailed MOT rules, please refer to our disclaimer.

Roughly how much does it cost to fix?

Costs vary widely depending on the root cause. Simple wiring repairs or connector cleaning may fall into the low two-figure range for parts, while sensor replacement typically sits in the low three-figure bracket (parts and labour combined). If the fault lies within the engine control module, expenses can reach the mid to high three-figure or even four-figure range at a main dealer. Independent garages often offer more competitive labour rates.

Can I clean the sensor myself to fix this?

Cleaning the connector and inspecting for obvious damage is straightforward, but P0368 usually indicates an electrical fault rather than dirt on the sensor element. If voltage tests confirm a short or the sensor itself has failed internally, replacement is typically necessary rather than cleaning.

P0368

Powertrain

Camshaft Position Sensor "B" Circuit High Input (Bank 1)

The engine control module has detected an unusually high voltage signal from the camshaft position sensor 'B' circuit on bank 1, typically indicating a wiring fault or sensor issue that may disrupt ignition and fuel timing.

ⓘ Information only. This page provides general educational information about fault code P0368. 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 P0368 mean?

P0368 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Camshaft Position Sensor "B" Circuit High Input (Bank 1).

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 P0368 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 P0368.

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
