What P068A means
The engine module switches its main relay coil to ground (control circuit), reads the switched voltage back on a sense line and keeps the relay on briefly after ignition off to save learned values. P068A means the relay dropped out before the module released it. Ford explains it as the non-volatile memory write after ignition off not being completed before the module lost power; the 2023 diesel checks continuously within 0.5 s. GM Europe's 2.0 diesel checks with the engine running for an unexpected loss of relay voltage (no MIL). VW (2017–18 Jetta 1.4 T) and Stellantis (2026 Dodge Charger 3.0 twin turbo) fixed false reports by software updates. Real triggers include disconnecting the battery right after switch-off and loose contacts in the relay supply; learned values may be lost.
P068A at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P068A
- Check engine light (Ford, VW, Stellantis)
- Often no noticeable symptoms
- Lost learned values, rough idle after restart
- With a contact fault: stalling or no start
Common causes of P068A
- Most likelyEngine module software (false report)
- PossibleBattery disconnected during or right after switch-off, or severe voltage dip
- PossibleOpen, high resistance or short to ground in the relay coil or contact supply
- Less likelyRelay faulty (drops out with vibration or heat)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P068A means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 6 | Area: computer (engine control module) and output circuits. |
| 8A | The exact fault in that area. |
What to do next
- Note P068A and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P068A
What does P068A mean?
P068A means "ECM/PCM Power Relay De-Energized Performance Too Early". The engine module switches its main relay coil to ground (control circuit), reads the switched voltage back on a sense line and keeps the relay on briefly after ignition off to save learned values. It is a generic code, so it means the same on every make.
Is it safe to drive with P068A?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P068A fail an emissions test?
Yes, it can. P068A is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P068A to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will P068A clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
