P0230 on RAM
Fuel Pump Primary Circuit Malfunction
P0230 on RAM vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 1 RAM model — most commonly on 1500. 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 RAM range from $50 to $1,200, 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 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 P0230 mean on RAM?▼
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 RAM specifically, this code is documented across 1 model.
What causes P0230 on RAM vehicles?▼
Common causes on RAM: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0230 on a RAM?▼
Repair costs on RAM range from $50 to $1,200, depending on the specific model and root cause.
