P0232 on Dodge
Fuel Pump Secondary Circuit - High
P0232 on Dodge vehicles indicates fuel pump secondary circuit - high. Au7o has documented this code across 5 Dodge models — most commonly on Caliber, Durango, Grand Caravan. 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 Dodge range from $50 to $1,500, 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 Dodge by Model
Dodge Caliber(1 issue)
- TIPM Electrical Module Failure2007-2012
Same TIPM design flaw as other Chrysler/Dodge products. Fuel pump relay failure, random electrical activations, and stalling. Can cause both engine and CVT issues through electrical malfunction.
Dodge Durango(1 issue)
- TIPM (Totally Integrated Power Module) Issues2011-2018
The TIPM can develop internal relay failures causing various electrical problems including no-start conditions, fuel pump not activating, horn honking randomly, and other erratic electrical behavior. This is a known Chrysler issue.
Dodge Grand Caravan(1 issue)
- TIPM (Totally Integrated Power Module) Failure2008-2020
The TIPM central fuse/relay box controls all vehicle electrical functions. Internal relays, especially fuel pump relay, fail from solder joint cracking due to thermal cycling. Causes random activation of lights/wipers/horn, sliding doors losing power, battery drain, and no-start conditions. Same TIPM design flaw as Chrysler Town & Country. Most severe in 2008 and 2010-2011.
Dodge Journey(2 issues)
- TIPM Electrical System Failure2009-2014
The TIPM experiences catastrophic failures affecting multiple systems. Fuel pump relay most common failure, causing vehicle to stall while driving. Other failures include power windows, locks, wipers, cruise control. Can drain battery or cause fires.
- Fuel Pump/Relay Failure (TIPM-Related)2009-2015
Fuel pump relay integrated into TIPM fails, preventing fuel pump activation or causing it to run continuously. Engine stalls due to loss of fuel pressure while driving. Most common TIPM failure mode, can strand drivers unexpectedly.
Dodge Nitro(1 issue)
- TIPM Stalling and No-Start2007-2011
The TIPM fuel pump relay and other relays fail, causing vehicle stalling while driving and no-start conditions. Same TIPM design flaw as all Chrysler/Dodge products of this era.

What does P0232 mean on Dodge?▼
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 Dodge specifically, this code is documented across 5 models.
