Code P0232 Ford Description

The P0232 code for Ford vehicles indicates a problem with the fuel pump secondary circuit being too high. This code is typically triggered when the powertrain control module (PCM) detects a voltage in the fuel pump secondary circuit that is above the specified range. The fuel pump secondary circuit is responsible for providing power to the fuel pump relay, which in turn controls the fuel pump's operation.

  • My ABS light goes on only when I first start moving, so I replaced the ABS sensor in the differential housing (Rear Anti-Lock Brake Sensor). And the light still goes on. So I borrowed a diagnosis tester from a friend and took a good drive only to find nothing about ABS light but a PO-232 Code on the tester saying Fuel Pump Secondary Circuit High. The truck (2000 Ford Ranger 2.5 L.). The truck runs great so I surely don't want to mess with this fuel pump problem. Any suggestions Thanks Brian

  • It's possible that your friends OBDII scanner can't read ABS codes. You have to have a scanner that can read ABS codes. If the ABS light is ON you should have a Cxxxx code. Without the code you will be able to properly diagnose the problem.
