P008A Low Pressure Fuel System Pressure - Too Low

Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modeNo

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.

Likely causes

Tank run empty or very low fuel level
In-tank pump or its control unit faulty
Filter or line restricted
Low-pressure sensor faulty

Symptoms

  • Check engine light on
  • Hard starting
  • Jerking under load
  • High-pressure codes may follow
