P0230 on Jeep
Fuel Pump Primary Circuit Malfunction
P0230 on Jeep vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 5 Jeep models — most commonly on Cherokee, Commander, Grand Cherokee. P0230 means the engine computer detected a fault in the fuel pump primary circuit — the control side that switches the fuel pump (or its relay) on and off. The PCM energizes this circuit to run the electric fuel pump that delivers fuel to the engine; if it sees voltage that is too high, too low, or out of expected range, it sets this code. Because the pump may not run correctly, the engine can crank without starting, stall, lose power, or hesitate. This is a circuit/control fault rather than a direct measurement of fuel pressure. Typical repair costs on Jeep range from $75 to $2,000, depending on the specific model and root cause.
Common Causes of P0230
- •Faulty fuel pump relay
- •Damaged wiring or connectors in the fuel pump control circuit
- •Corroded or loose ground/power connection
- •Failed fuel pump or fuel pump driver module
- •Blown fuse or fusible link
- •Open or short in the primary control wiring
- •Faulty PCM driver output (rare)
P0230 on Jeep by Model
Jeep Cherokee(1 issue)
- TIPM Fuel Pump Relay Failure2014-2023
The Totally Integrated Power Module fuel pump relay fails, causing no-start conditions or fuel pump running continuously. Unlike older models, the relay is integrated and cannot be replaced separately.
Jeep Commander(1 issue)
- Engine Stalling / Loss of Power While Driving2006-2010
The Commander can stall or lose engine power without warning at any speed. The problem is linked to multiple causes: faulty crankshaft position sensor, failing fuel pump, PCM software bugs, and throttle body issues. Over 173 engine complaints were filed for the 2006 model year. Some owners report engine compartment fires linked to electrical shorts in the PCM area.
Jeep Grand Cherokee(1 issue)
- TIPM (Fuse Box) Failure2011-2017
The Totally Integrated Power Module (TIPM) can fail, causing various electrical issues including fuel pump relay problems (no start), random horn honking, and erratic behavior of lights and accessories.
Jeep Renegade(1 issue)
- Sudden Power Loss / Engine Stalling While Driving2015-2019
Owners report sudden and complete loss of power while driving at highway speeds without warning. The engine may stall, lose throttle response, or go into limp mode unexpectedly. Contributing factors include throttle body failure, fuel pump issues, and PCM software bugs. This is especially dangerous on highways as power steering and power brakes are compromised when the engine stalls.
Jeep Wrangler(1 issue)
- TIPM (Totally Integrated Power Module) Failure2007-2016
The TIPM can develop internal relay failures causing various electrical problems including fuel pump not activating, horn honking randomly, wipers activating on their own, and other erratic electrical behavior. This is a well-known issue across Chrysler vehicles.

What does P0230 mean on Jeep?▼
P0230 stands for "Fuel Pump Primary Circuit Malfunction." P0230 means the engine computer detected a fault in the fuel pump primary circuit — the control side that switches the fuel pump (or its relay) on and off. The PCM energizes this circuit to run the electric fuel pump that delivers fuel to the engine; if it sees voltage that is too high, too low, or out of expected range, it sets this code. Because the pump may not run correctly, the engine can crank without starting, stall, lose power, or hesitate. This is a circuit/control fault rather than a direct measurement of fuel pressure. On Jeep specifically, this code is documented across 5 models.
What causes P0230 on Jeep vehicles?▼
