The automobile fault code P1238 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of the repair will depend on the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

The P1238 fault code points to a problem with the fuel pump secondary circuit. This means that the Fuel Pump Driver Module (FPDM2) has detected an issue and sends a message to the Powertrain Control Module (PCM) through the fuel pump monitor (FPM2) circuit.

Once the PCM receives this message, it sets the P1238 code.

In simpler terms, this fault code indicates that there is a concern with the fuel pump secondary circuit.

It is important to address this issue promptly to ensure proper functioning of the fuel pump and overall performance of the vehicle.

What are the possible causes for the automobile fault code P1238 and how can I visually inspect them?

If you’re seeing the P1238 fault code and your engine light is on, it could be due to 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 wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins in the connectors. This will help you identify and fix the issue.

How can I determine if the Fuel Pump Driver Module (FPDM) is faulty and what steps should I take to fix it?

If you notice the Engine Light ON or the Service Engine Soon Warning Light, it could be a sign of a faulty Fuel Pump Driver Module (FPDM). To determine if this is the issue, visually inspect the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded connector pins. If you find any issues, fix or replace the damaged components accordingly.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors for the P1238 fault code?
