P0232 on Jeep
Fuel Pump Secondary Circuit - High
P0232 on Jeep vehicles indicates fuel pump secondary circuit - high. Au7o has documented this code across 5 Jeep models — most commonly on Cherokee, Commander, Grand Cherokee. This code means the engine computer has detected a high voltage signal in the fuel pump secondary (control) circuit, indicating the circuit that drives or monitors the fuel pump relay is reading higher than it should. The computer controls fuel pump power delivery through a relay and/or driver module, and a high reading suggests a short to voltage, a stuck relay, or a wiring fault in that control circuit. Depending on the fault, it can cause hard starting, stalling, or a no-start because fuel delivery is disrupted. The problem is typically electrical, in the relay, driver, or wiring, rather than the pump motor itself. Typical repair costs on Jeep range from $75 to $2,000, depending on the specific model and root cause.
Common Causes of P0232
- •Faulty fuel pump relay (stuck or shorted)
- •Short to voltage in the fuel pump control wiring
- •Failed fuel pump driver module
- •Corroded or damaged connectors in the circuit
- •Faulty fuel pump (internal short)
- •Wiring chafed against the body or harness short
- •Faulty PCM/ECM (rare)
P0232 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 P0232 mean on Jeep?▼
P0232 stands for "Fuel Pump Secondary Circuit - High." This code means the engine computer has detected a high voltage signal in the fuel pump secondary (control) circuit, indicating the circuit that drives or monitors the fuel pump relay is reading higher than it should. The computer controls fuel pump power delivery through a relay and/or driver module, and a high reading suggests a short to voltage, a stuck relay, or a wiring fault in that control circuit. Depending on the fault, it can cause hard starting, stalling, or a no-start because fuel delivery is disrupted. The problem is typically electrical, in the relay, driver, or wiring, rather than the pump motor itself. On Jeep specifically, this code is documented across 5 models.
What causes P0232 on Jeep vehicles?▼
Common causes on Jeep: Faulty fuel pump relay (stuck or shorted), Short to voltage in the fuel pump control wiring, Failed fuel pump driver module, Corroded or damaged connectors in the circuit, Faulty fuel pump (internal short). Specific causes vary by model and year — see the per-model sections below.
