  • Faulty low-side fuel pressure sensor
  • Problems with the fuel pump, fuel pump control module, or fuel filter

What are the symptoms of the P008A code?

The P008A code is often accompanied by the check engine light and multiple codes. There may be an oxygen sensor code or codes indicating that the vehicle is running rich or lean. The vehicle can also misfire because of fuel conditions, and it may run rough or experience an inability to accelerate.

  • They will check the sensor and measure the pressure in the supply lines indicates if the sensor is bad.

What repairs can fix the P008A code?

The most common repairs used to address the P008A code are:
