P008D Fault Code

P008D OBD-II Trouble Code Short Description

Fuel Cooler Pump Control Circuit Low

What does trouble code P008D mean?

The P008D fault code indicates a problem with the fuel cooler pump control circuit being low. This means that the power or signal to the fuel cooler pump is weaker than normal, potentially leading to issues with fuel cooling and overall engine performance.

The solution to this issue usually involves checking the wiring and connections related to the fuel cooler pump, as well as testing the pump itself for proper function. If any faulty components are found, they should be repaired or replaced as needed to restore proper operation of the fuel cooler pump.

It is important to address this issue promptly as a malfunctioning fuel cooler pump can impact fuel efficiency and engine performance. Ignoring this fault code could potentially lead to further damage to the engine or fuel system, resulting in more costly repairs down the line.


What are the symptoms of the P008D code?

  • Engine stalling
  • Decreased engine performance
  • Check Engine Light illuminating
  • Fuel odor from the vehicle
  • Problems starting the engine


What causes the P008D code?

When the P008D fault code appears on a car, it is typically caused by the following:

  • Faulty fuel cooler pump
  • Wiring issues in the fuel cooler pump circuit
  • Low voltage in the fuel cooler pump circuit

It is recommended to inspect the fuel cooler pump, check the wiring for any damage, and verify the voltage in the circuit to diagnose and resolve the P008D fault code.
