P0230 on RAM by model: symptoms, diagnosis and fix
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.
Common Symptoms
- No start condition
- Fuel pump not priming
- Random horn honking
- Headlights flickering
- Wipers activating randomly
- Battery drain
- Multiple warning lights on dash
How to Fix
For fuel pump relay failure: Install an external bypass relay kit ($30-50 DIY) to power fuel pump directly. For complete TIPM replacement: Use remanufactured unit ($400-600) or new OEM ($800-1,200). Some electrical shops can rebuild existing TIPM for $200-400. The TIPM class-action settlement covered only 2011-2013 Dodge Durango and Jeep Grand Cherokee, not the Ram 1500, and its claim deadline has passed, so Ram owners pay for this repair unless the truck is still under warranty.

Owner tips & cautions
- WarningThis is a high-severity issue - ignoring it can lead to costly repairs or safety concerns. Address it promptly.
- TipConsider OEM parts for critical components like sensors and electrical parts - aftermarket can be unreliable
- TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes

The Totally Integrated Power Module (TIPM) contains a fuel-pump relay soldered to its circuit board. When it fails it cuts power to the fuel pump, causing a crank-no-start that mimics running out of gas, or a sudden stall while driving; sometimes the pump keeps running with the key off and drains the battery. The relay is non-serviceable inside the module, making this a well-known and expensive Chrysler/Ram electrical failure across 2011-2018 trucks.
Common Symptoms
- Crank but no start (acts out of fuel)
- Random stalling while driving
- Fuel pump runs with key off / battery drain
- Intermittent no-start
- Multiple electrical gremlins
How to Fix
Confirm by monitoring fuel-pump power/relay operation. Options in ascending cost: install a fuel-pump relay bypass cable or plug-in external relay, or install Chrysler's external fuel-pump relay relocation kit (Mopar 68142156AA) to move the relay out of the TIPM. If other TIPM circuits are also faulty, replace/rebuild the TIPM (must be programmed to the VIN). Specialty shops repair the original board for far less than a new module.

Frequently asked questions
What does P0230 mean on a 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 it is documented across 1 model: 1500.
What are the most common causes of P0230?
The most common causes of P0230 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0230 on a RAM?
Published repair estimates on RAM range from $50 to $1,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
