P1232 FORD Possible Causes
- Faulty low-speed fuel pump
- Defective fuel pump relay
- Low-speed fuel pump wiring harness is open or short-circuited
- Poor electrical connection in the low-speed fuel pump circuit
- Damaged Powertrain Control Module (PCM)
How to Fix P1232 FORD Code?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.
Technical Notes
The Powertrain Control Module (PCM) monitors the output of the low-speed fuel pump (LFP) primary circuit from the PCM. The test fails if: when the LFP circuit is activated (grounded), excessive current consumption is detected in the LFP circuit; or when the LFP circuit is deactivated, voltage is not detected in the LFP circuit (the PCM expects to detect VPWR voltage passing through the low-speed fuel pump relay coil to the LFP circuit).
Possible Symptoms
- Check Engine Light on (or Service Engine Soon warning light)
