P0230 on Dodge
Fuel Pump Primary Circuit Malfunction
P0230 on Dodge vehicles indicates fuel pump primary circuit malfunction. Au7o has documented this code across 5 Dodge models — most commonly on Caliber, Durango, Grand Caravan. 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 Dodge range from $50 to $1,500, 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 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 P0230 mean on Dodge?▼
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 Dodge specifically, this code is documented across 5 models.
