P0232: Fuel Pump Secondary Circuit - High
36 vehicles · 12 makes · $50-$2,000 repair
Most Reported On
P0232 is an OBD-II diagnostic trouble code meaning “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. This code is most commonly reported on 2018-2021 Honda Accord, 2018-2022 Honda CR-V, and 2011-2016 Chrysler 300, plus 33 other vehicles, with repair costs ranging from $50 to $2,000.

FAQ
What does P0232 mean?
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.
What are the most common causes of P0232?
The most common causes of P0232 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0232?
Repair costs for P0232 range from $50 to $2,000, depending on the vehicle and root cause.
