P008A on Genesis
Low Pressure Fuel System Pressure - Too Low
P008A on Genesis vehicles indicates low pressure fuel system pressure - too low. Au7o has documented this code across 1 Genesis model — most commonly on GV70. Generic OBD-II code, most often seen on direct-injection and diesel vehicles that use both a low-pressure lift pump and a high-pressure pump. The PCM compares the commanded low-side fuel pressure to what the low-pressure fuel sensor reports and sets this code when actual pressure (or fuel volume/flow) falls below the expected value. Because the high-pressure pump is starved, the engine can run lean, misfire, hesitate under load, crank a long time, stall, or go into reduced-power mode. This one should not be ignored - sustained low supply pressure can damage the high-pressure pump. Note that some manufacturers define this code slightly differently.
Common Causes of P008A
- •Weak or failing in-tank fuel pump / lift pump
- •Clogged fuel filter or restricted fuel line
- •Faulty low-pressure fuel or fuel rail pressure sensor giving a false low reading
- •Leaking fuel line, injector, or pressure regulator on the low-pressure side
- •Low fuel level or contaminated/wrong fuel
- •Fuel pump control module or wiring/relay fault

- Low-Pressure Fuel Pump Impeller Failure Causing Stalling2022-2023
The low-pressure fuel pump assembly can contain an impeller made from material that does not meet specification. Under high ambient temperatures the impeller deforms and interferes with the pump housing, creating mechanical resistance that shuts the pump down and starves the engine of fuel. The result is a sudden loss of motive power or an engine stall while driving, which can happen at speed and create a crash risk. Genesis addressed it under safety recalls 016G and 022G (NHTSA 23V-630 and 24V-282), covering 2022-2023 GV70 along with G80/GV80/G90.

What does P008A mean on Genesis?▼
P008A stands for "Low Pressure Fuel System Pressure - Too Low." Generic OBD-II code, most often seen on direct-injection and diesel vehicles that use both a low-pressure lift pump and a high-pressure pump. The PCM compares the commanded low-side fuel pressure to what the low-pressure fuel sensor reports and sets this code when actual pressure (or fuel volume/flow) falls below the expected value. Because the high-pressure pump is starved, the engine can run lean, misfire, hesitate under load, crank a long time, stall, or go into reduced-power mode. This one should not be ignored - sustained low supply pressure can damage the high-pressure pump. Note that some manufacturers define this code slightly differently. On Genesis specifically, this code is documented across 1 model.
What causes P008A on Genesis vehicles?▼
Common causes on Genesis: Weak or failing in-tank fuel pump / lift pump, Clogged fuel filter or restricted fuel line, Faulty low-pressure fuel or fuel rail pressure sensor giving a false low reading, Leaking fuel line, injector, or pressure regulator on the low-pressure side, Low fuel level or contaminated/wrong fuel. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P008A on a Genesis?▼
Repair costs vary widely depending on the root cause and specific Genesis model.
