2018 Kia Sorento P0627 Fuel Pump 'A' Control Circuit Open - Diagnosis and Repair Help

Model: 2018 Kia Sorento Fault Code: P0627 Posted: 2021-09-15 15:21

Hi everyone, I'm currently dealing with a persistent P0627 fault code on my 2018 Kia Sorento, which indicates a 'Fuel Pump A Control Circuit Open'. After taking the vehicle to the local dealer, they diagnosed the issue as a faulty fuel pump and recommended replacement. However, I was not satisfied with their pricing and decided to replace the fuel pump myself. Despite this repair, the P0627 code continues to appear. I've already checked the fuses and relays, and they appear to be functioning correctly. I'm now looking for further troubleshooting steps or potential causes that might be responsible for this recurring error. Any insights or suggestions would be greatly appreciated.

The P0627 code suggests a problem in the fuel pump 'A' control circuit — it's essential to systematically test the wiring, relay, and module. A digital multimeter (DVM) is recommended for accurate voltage and continuity checks. Referencing the vehicle-specific wiring diagram will help identify potential fault points in the circuit.

Have you tried using a diagnostic scanner to check for any additional related codes or live data? This could provide more context on whether the issue is electrical, sensor-related, or still tied to the fuel pump module.
