[SOLVED] P1235 Code: Fuel Pump Control Out Of Range – How To Fix It!

The automobile fault code P1235 indicates a problem with the Fuel Pump Drive 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 Powertrain Control Module (PCM).

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0.

It is important to address this problem promptly to ensure proper functioning of the fuel pump system.

The factors influencing the diagnosis and fixing cost of the automobile fault code P1235 are the estimated repair time and the hourly rate charged by auto repair shops.

The estimated repair time for this fault code is 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services. These factors will determine the overall cost of diagnosing and fixing the P1235 fault code.

The P1235 code means that the Fuel Pump Drive Module (FPDM) has detected a problem with the Fuel Pump (FP) circuit signal from the Powertrain Control Module (PCM).

This code is set when the FPDM sends a message to the PCM indicating that an invalid or missing signal was detected.

In simpler terms, it means there is an issue with the fuel pump control that needs to be addressed.

What are the possible causes of the automobile fault code P1235?

If you see the engine light or service engine soon warning light on, the fault code P1235 could be the culprit. This code is often caused by a faulty fuel pump drive module (FPDM), an open or shorted FPDM harness, a poor electrical connection in the FPDM circuit, or a faulty powertrain control module (PCM). To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to address the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the P1235 fault code?

If you’re dealing with the P1235 fault code and your engine light is on, it’s time to take action. The culprit could be a faulty Fuel Pump Drive Module (FPDM), an open or shorted FPDM harness, a poor electrical connection in the FPDM circuit, or even a faulty Powertrain Control Module (PCM). To fix this issue, start by visually inspecting the wiring harness and connectors. Look out for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t delay, get to the bottom of this problem now!

What should I look for when checking for damaged components or corroded connector pins to resolve the P1235 fault code?

When resolving the P1235 fault code, start by checking for damaged components or corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. These issues can cause a poor electrical connection or an open/short circuit, leading to the faulty fuel pump drive module or powertrain control module. By addressing these possible causes, you can fix the issue and turn off the engine light or service engine soon warning light.
