The automobile fault code P1236 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 automobile fault code P1236 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of the repair is typically charged by most auto repair shops between $75 and $150 per hour.

The P1236 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, the P1236 code tells us that there is an issue with the fuel pump control.

The FPDM is not receiving the correct signal from the PCM, which can cause problems with the fuel pump’s operation. This can lead to issues with fuel delivery and potentially affect the performance of the vehicle. If you see the P1236 code on your vehicle’s diagnostic scanner, it’s important to have it checked and repaired as soon as possible.

Ignoring this issue can lead to further damage and potentially leave you stranded on the road. A qualified mechanic will be able to diagnose the exact cause of the problem and fix it accordingly.

What are the possible causes of the automobile fault code P1236?

If you see the engine light or service engine soon warning light on, the fault code P1236 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. Don’t forget to consider the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the P1236 fault code?

If you’re dealing with the P1236 fault code and your engine light is on, it’s time to take action. The most common causes for this code are 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, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken, bent, pushed out, or corroded pins. This step is crucial in identifying and resolving the problem.

What should I look for when checking for damaged components and connector pins to resolve the P1236 fault code?
