C052F code meaning
ABS Pump Motor Supply Voltage Circuit/Open
What C052F means
The pump motor has its own battery feed, separate from the logic supply, and this code reports that feed as missing or open. Mitsubishi's 2023 Outlander PHEV manual shows the layout: motor and motor relay draw from a 60 A fusible link and must see 10–16 V at the unit connector, the valves from a separate 50 A link, the electronics from a 5 A fuse. Mitsubishi itself reports such a loss through its pump motor code and lists fuse, fusible link and 12 V battery as causes, not via C052F. An AlliedSignal patent (now Bosch) logs a separate fault when the motor voltage at switch-off is below about 7 V. Because the electronics stay powered, the module still communicates and lights the ABS lamp while the pump is dead.
C052F at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C052F
- ABS and ESC warning lamps on
- Pump motor never runs, ABS and stability control off
Common causes of C052F
- Most likelyPump motor fuse or fusible link blown
- PossibleCorroded or loose battery feed terminal at the ABS connector
- PossibleOpen or high-resistance ground of the ABS unit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

| 0 | Generic code: it means the same on every make (SAE standard). |
| 2F | The exact fault in that area. |
What to do next
- Note C052F 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 C052F
What does C052F mean?
C052F means "ABS Pump Motor Supply Voltage Circuit/Open". The pump motor has its own battery feed, separate from the logic supply, and this code reports that feed as missing or open. It is a generic code, so it means the same on every make.
Is it safe to drive with C052F?
Drive gently and only to a workshop. With C052F the car can go into limp mode (reduced power) to protect itself.
Will C052F fail an emissions test?
C052F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C052F to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will C052F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
