P0231 on Chrysler
Fuel Pump Secondary Circuit - Low
P0231 on Chrysler vehicles indicates fuel pump secondary circuit - low. Au7o has documented this code across 4 Chrysler models — most commonly on 300, Aspen, Sebring. This code indicates the engine computer detected a low-voltage condition in the fuel pump's secondary (driver/output) control circuit. Many vehicles control the fuel pump through a relay or a dedicated driver module, and the computer monitors the voltage on that circuit to confirm the pump is being powered correctly. When the feedback voltage stays lower than expected, P0231 sets. Because the fuel pump supplies pressurized fuel to the injectors, this fault can cause hard starting, stalling, or no-start conditions. Typical repair costs on Chrysler range from $50 to $1,500, depending on the specific model and root cause.
Common Causes of P0231
- •Faulty fuel pump relay
- •Corroded or loose connector at the pump or relay
- •Damaged or shorted wiring in the pump power circuit
- •Poor ground for the fuel pump circuit
- •Failing fuel pump drawing abnormal current
- •Faulty fuel pump driver module
- •PCM/ECM internal driver fault (rare)
P0231 on Chrysler by Model
Chrysler 300(2 issues)
- TIPM Electrical Failures2011-2016
The TIPM main fuse and relay box circuit board traces blow from current spikes, shorts, or corrosion. Water intrusion common. Causes random electrical issues affecting fuel pump, lights, wipers, horn, windows, and safety systems.
- Fuel Pump Relay Failure (TIPM-Related)2011-2016
Fuel pump relay inside TIPM fails, preventing fuel pump activation. Vehicle has full electrical power but won't start due to no fuel delivery. Related to broader TIPM issue, specifically affects ASD/Fuel Pump relay circuits.
Chrysler Aspen(1 issue)
- TIPM Electrical Module Failure2007-2009
The Aspen shares the TIPM electrical module design with other Chrysler products. Fuel pump relay failure, random electrical activation, and battery drain are common. Same fundamental TIPM design flaw as Town & Country and 300.
Chrysler Sebring(1 issue)
- TIPM (Totally Integrated Power Module) Failure2007-2010
The Totally Integrated Power Module (TIPM), located in the engine compartment near the air cleaner assembly, houses all important fuses and power relays. Water intrusion into the module can cause corrosion and electrical system failures. The TIPM controls critical systems including fuel pump operation, headlights, airbags, door locks, and air conditioning.
Chrysler Town & Country(1 issue)
- TIPM (Totally Integrated Power Module) Failure2008-2016
The TIPM central fuse/relay box controls nearly all vehicle electrical functions. Internal relays, especially the fuel pump relay, fail due to solder joint cracking from thermal cycling. Causes random activation of lights, wipers, horn, sliding doors losing power, battery drain, and no-start conditions. Class-action lawsuit filed. Most severe in 2008 and 2010-2011 model years.

What does P0231 mean on Chrysler?▼
P0231 stands for "Fuel Pump Secondary Circuit - Low." This code indicates the engine computer detected a low-voltage condition in the fuel pump's secondary (driver/output) control circuit. Many vehicles control the fuel pump through a relay or a dedicated driver module, and the computer monitors the voltage on that circuit to confirm the pump is being powered correctly. When the feedback voltage stays lower than expected, P0231 sets. Because the fuel pump supplies pressurized fuel to the injectors, this fault can cause hard starting, stalling, or no-start conditions. On Chrysler specifically, this code is documented across 4 models.
What causes P0231 on Chrysler vehicles?▼
Common causes on Chrysler: Faulty fuel pump relay, Corroded or loose connector at the pump or relay, Damaged or shorted wiring in the pump power circuit, Poor ground for the fuel pump circuit, Failing fuel pump drawing abnormal current.
