P008ALow Pressure Fuel System Pressure - Too Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- Some engines, mainly gasoline direct injection with a demand-controlled in-tank pump, have their own pressure sensor in the low-pressure line between the tank pump and the high-pressure pump. The engine control module compares this supply pressure with its target. P008A is set when the supply pressure stays too low. Besides a weak tank pump or its control unit, a clogged filter or a faulty sensor, simply running the tank empty can set this code.
