P060C

What it means

P060C is a generic code meaning the engine or powertrain control module has detected a performance fault in its own main processor. The module runs internal self-checks on the processor, and the code sets when those checks fail or the results disagree with what is expected. The fault is usually inside the module or its power and ground supply, and the exact monitoring method varies by manufacturer and model.

Symptoms

• Engine management warning light on
• Engine running in limp mode with reduced power
• Engine misfiring, stalling or failing to start
• Erratic or no response from the throttle
• Other warning lights or multiple unrelated fault codes stored
• Intermittent fault that appears and clears

Possible causes

• Low or unstable supply voltage to the control module from a weak battery or poor charginglikely
• Poor module power or earth connection, including corroded or loose terminals and connectorslikely
• Internal fault in the control module main processorpossible
• Outdated or corrupted module software or calibrationpossible
• Water ingress or corrosion inside the module or its connectorpossible
• Shorted sensor or actuator pulling down the module's reference supply or overloading its driversrare
• Previous incorrect repair or programming attempt that left the module in a faulty staterare

How to diagnose

1. Read all stored and pending codes and note freeze frame data, then record whether the fault is current or historic
2. Check for other codes, especially supply voltage, communication or sensor reference faults, and address those first
3. Test battery condition and the charging system output to confirm stable voltage under load
4. Inspect module connectors, fuses, relays and earth points for corrosion, damage, moisture or looseness
5. Voltage drop test the module power and earth circuits with the ignition on and while cranking
6. Check the manufacturer's service information for known software updates or bulletins for this model and engine
7. Clear the code, road test and recheck to see whether it returns immediately or only under certain conditions
8. Only if everything else is sound, have the module tested or its internal self-checks confirmed using the manufacturer's procedure

How to fix

• Replace or recharge a weak battery and repair any charging system fault
• Repair or clean corroded or loose power, earth and connector terminals
• Update or reprogram the module software when an updated calibration is available for the vehicle
• Dry out and repair any water ingress source, and replace the module if it is corroded
• Repair wiring faults or replace any shorted component loading the module
• Replace or repair the control module and have it coded to the vehicle as the manufacturer specifies
