P0232 on RAM
Fuel Pump Secondary Circuit - High
P0232 on RAM vehicles indicates fuel pump secondary circuit - high. Au7o has documented this code across 1 RAM model — most commonly on 1500. 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 RAM range from $50 to $1,200, 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 RAM by Model
RAM 1500(1 issue)
- TIPM (Totally Integrated Power Module) Failure2009-2016
The TIPM controls most electrical functions and commonly fails, causing erratic behavior. The fuel pump relay inside the TIPM is particularly prone to failure, resulting in no-start conditions. Horn honking randomly, headlights flickering, and wipers activating on their own are common symptoms.

What does P0232 mean on RAM?▼
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 RAM specifically, this code is documented across 1 model.
What causes P0232 on RAM vehicles?▼
Common causes on RAM: 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.
How much does it cost to fix P0232 on a RAM?▼
Repair costs on RAM range from $50 to $1,200, depending on the specific model and root cause.
