Is it safe to drive with this code?

Driving may be possible in many cases, but the hybrid system may operate in a reduced-power or restricted mode, and you may experience reduced electric range or increased reliance on the petrol engine. Continued driving risks further damage to expensive hybrid components; see our disclaimer and seek workshop diagnosis promptly.

It may affect the MOT result if the malfunction indicator lamp is illuminated at the time of the test—what matters is whether the warning light is lit during the inspection. Refer to our site disclaimer for full guidance.

Roughly how much does it cost to fix?

Diagnosis typically takes around one hour of labour, often in the low to mid three-figure range depending on your location and whether you use an independent or a main dealer. If only wiring or connector repairs are needed, total costs may remain in the low to mid three-figure bracket. However, if the generator resolver or transaxle assembly itself requires replacement, costs can climb to the high three-figure to four-figure range, particularly at franchised dealers.

Can I reset the code and keep driving?

Clearing the code without addressing the underlying cause may result in the fault returning, and continuing to drive with an unresolved high-voltage sensor issue can potentially cause further harm to the hybrid system. Proper diagnosis and repair are strongly recommended before extended use.

P0C6C

Powertrain

Generator Position Sensor Circuit "B" High

The hybrid generator position sensor circuit 'B' is reporting a voltage reading that is higher than expected, which may affect the hybrid system's ability to control the motor-generator efficiently.

ⓘ Information only. This page provides general educational information about fault code P0C6C. 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.
