P2635 OBD-II: Fuel Pump "A" Low Flow/Performance
P2635 Severity
Should you fix P2635 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P2635?
The Fuel Pump Control Module determines the required amount of fuel pressure to keep the engine running efficiently. It then commands the fuel pump to operate accordingly to maintain the required fuel pressure. If the Fuel Pump Module sees that the actual fuel pressure does not meet the commanded fuel pressure, code P2635 will set.
