P0232 on Volvo
Fuel Pump Secondary Circuit - High
P0232 on Volvo vehicles indicates fuel pump secondary circuit - high. Au7o has documented this code across 1 Volvo model — most commonly on XC90. 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.
Common Causes of P0232
- •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)

What does P0232 mean on Volvo?▼
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.
