The automobile fault code P1237 indicates a problem with the Fuel Pump Driver Module (FPDM).
The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.
The cause could be a faulty FPDM, an open or shorted FPDM harness, a poor electrical connection in the FPDM circuit, or a faulty fuel pump. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.
Look out for broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 10.0 (Out of 10) |
The fault code on your car’s dashboard isn’t always reliable. That’s why it’s smart to keep an OBD scanner in your toolbox for quick, accurate diagnostics.

P1237 Fault Code: Understanding The Description And Troubleshooting Steps
The P1237 code refers to a fuel pump secondary circuit fault. This fault is detected by the Fuel Pump Driver Module (FPDM), which controls the voltage to the fuel pump to maintain proper fuel pressure.
The FPDM sends a message to the Powertrain Control Module (PCM) through the Fuel Pump Monitor (FPM) circuit when it detects this concern. The PCM then sets the Diagnostic Trouble Code (DTC) P1237.
This code indicates that there is an issue with the fuel pump secondary circuit.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P1237 could be the culprit. This code is often caused by a faulty Fuel Pump Driver Module (FPDM), an open or shorted FPDM harness, a poor electrical connection in the FPDM circuit, or a faulty fuel pump. To visually inspect these possible causes, check the related wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins. Don’t forget to examine the components as well.
If you’re experiencing the dreaded P1237 fault code, with the engine light or service engine soon warning light on, the culprit could be a faulty Fuel Pump Driver Module (FPDM). To confirm this, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Look out for broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to also consider other possible causes like a faulty fuel pump or poor electrical connection in the FPDM circuit.
To fix the P1237 fault code, start by visually inspecting the related wiring harness and connectors.
