Code P1232 2001 Ford F150 Description

The P1232 diagnostic trouble code (DTC) for a 2001 Ford F150 indicates a Low Speed Fuel Pump Primary Circuit Failure. This code is triggered when the powertrain control module (PCM) detects an issue with the primary circuit of the low-speed fuel pump. The fuel pump is responsible for delivering fuel from the tank to the engine, and a malfunction in this circuit can lead to various performance issues.

Tech Notes for P1232 2001 Ford F150

The Powertrain Control Module (PCM) monitors the Low Speed Fuel Pump (LFP) primary circuit output from the PCM. The test fails if: When the LFP circuit is commanded on (grounded), excessive current draw is detected on the LFP circuit; or when the LFP circuit is commanded off, voltage is not detected on the LFP circuit (the PCM expects to detect VPWR voltage coming through the low speed fuel pump relay coil to the LFP circuit).
