Low or unstable battery voltage or poor charging system output causing the control unit to reset or fail self-tests; Poor power or earth supply to the control unit, such as corroded or loose connections or a blown fuse; Corroded, damaged or water-affected control unit connector pins or wiring; Internal fault in the control module (processor or memory failure); Outdated or faulty control unit software where the manufacturer has issued a known correction; Water ingress or heat damage to the control unit housing; Faulty wiring or short on a sensor supply affecting the unit's operation.

P: SystemPowertrain
0: Defined bySAE, the same on every car
6: AreaComputer and output circuits
0A: FaultThe specific fault in that area

What it means

P060A means the engine or powertrain control module has detected a fault in the performance of its own internal monitoring processor. This processor acts as an independent watchdog that checks the main processor's calculations and safety functions. If the two do not agree, or the monitoring processor fails its self-tests, the code is set and the unit may restrict engine output.

Symptoms

Engine warning light on
Reduced power or limp mode
Engine cranks but will not start, or stalls
Rough running or hesitation
Other control unit communication or fault codes stored at the same time
Intermittent fault that comes and goes

Possible causes

Low or unstable battery voltage or poor charging system output causing the control unit to reset or fail self-testslikely
Poor power or earth supply to the control unit, such as corroded or loose connections or a blown fuselikely
Corroded, damaged or water-affected control unit connector pins or wiringpossible
Internal fault in the control module (processor or memory failure)possible
Outdated or faulty control unit software where the manufacturer has issued a known correctionpossible
Water ingress or heat damage to the control unit housingrare
Faulty wiring or short on a sensor supply affecting the unit's operationrare

How to diagnose

Read all stored and pending codes and freeze frame data, noting whether other module or voltage-related codes are present
Test battery condition and charging voltage with the engine running and under load
Check relevant fuses and relays supplying the control unit, and inspect the main power and earth connections for tightness and corrosion
Inspect the control unit connectors and wiring for water, corrosion, bent pins or chafing
Check the control unit housing and surrounding area for moisture or heat damage
Clear the code, road test and see whether it returns immediately or only under certain conditions
Check for manufacturer service bulletins or available software updates for the specific model and engine
Only after power, earth and wiring are proven sound, consider the control unit itself as faulty

How to fix

Replace or recharge a weak battery and repair any charging system fault
Repair or replace faulty power and earth connections, fuses or relays
Clean or repair corroded connectors and damaged wiring, and deal with the source of any water ingress
Update the control unit software to the latest manufacturer release where an outdated calibration is a known cause
Repair or replace the control unit if it has an internal fault, and have it programmed or coded to the vehicle as the manufacturer requires

Medium severity

The car may be driveable if it runs normally, but the fault can cause stalling, no-start or limp mode without warning. Have it checked soon and avoid long journeys or situations where a sudden loss of power would be unsafe.
