What P0B0C means
P0B0C says the circuit fed by auxiliary pump A loses pressure through a leak, so the pump cannot hold the demanded pressure. Stellantis documents it as P0B0C 7A for the 2023-26 Jeep Avenger and 2026 Compass with hybrid dual-clutch transmission outside the US (TSB 21-061-26): an internal leak at the parking pawl locking piston causes jerking and power loss and may stop the engine from restarting after a stop; with P07E4 or P07E6 present and more than 5 km on the clock, the piston or the transmission is replaced. How a controller can see a leak shows a Nidec patent: after a speed change the pump current keeps falling instead of recovering, and the pump is stopped. P0B0B and P0B09 cover the supply, P2797 a pump that does not deliver.
P0B0C at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor2 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0B0C
- Jerking and loss of power while driving
- Engine fails to restart after a stop
- Transmission warning, possibly with P07E4 or P07E6
Common causes of P0B0C
- Most likelyInternal leak at the parking pawl locking piston (Jeep Avenger/Compass hybrid DCT)
- PossibleWorn seal or valve leaking inside the hydraulic circuit
- PossibleExternal leak and low transmission fluid level
- Less likelyInternal wear of the auxiliary pump
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0B0C means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| B | Area: hybrid propulsion. |
| 0C | The exact fault in that area. |
What to do next
- Note P0B0C 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 P0B0C
What does P0B0C mean?
P0B0C means "Electric/Auxiliary Transmission Fluid Pump A Hydraulic Leakage". P0B0C says the circuit fed by auxiliary pump A loses pressure through a leak, so the pump cannot hold the demanded pressure. It is a generic code, so it means the same on every make.
Is it safe to drive with P0B0C?
Drive gently and only to a workshop. With P0B0C the car can go into limp mode (reduced power) to protect itself.
Will P0B0C fail an emissions test?
P0B0C 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 P0B0C to fix?
Difficulty: workshop only. A typical repair takes 2 to 8 hours of work. This is a job for a workshop.
Will P0B0C clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
