Guide To P008A OBD Error Code Solutions

<<See All OBD Codes

P008A is a generic code which would start appearing when a low-pressure fuel system starts reaching levels that are too low or on the other side the readings may become out of tolerance. It means that the fuel has entered into the system and has started sending a false signal.

When the fuel has started to enter into the system and has started sending the wrong signals because of a damaged fuel pressure sensor then P008A code would start triggering up. This code would indicate that the fuel pressure is below the specification for the supply needed for the vehicle to operate.

What causes this problem with the Low Pressure Fuel System Pressure?

• The fuel may become dirty
• Plugged fuel filter
• You may start facing restrictions in the fuel line like kinked, clogged, etc.
• Fuel pump pickup may become dirty
• The fuel may become unstable
• Fuel injector can become defective
• Weak low pressure in the fuel pump
• The car fuel may become sludgy like old, thick, contaminated

1. Fuel Filter - Common cause behind this P008A error code can be some fault in Fuel Filter. So, it will be a good decision to replace them now.
2. Fuel Injector - Another reason for P008A error is the faulty Fuel Injector and its parts. To remove the error, immediate replacement is in order.
3. Fuel Pressure Sensor - P008A error code may also flash due to problems with the Fuel Pressure Sensor. Replace the Fuel Pressure Sensor now with us at economical prices.
4. Fuel Pump - A damaged fuel pump will not be able to supply proper fuel to the engine resulting in engine stalling and sometimes not starting resulting the OBD error code P008A. Immediate replacement of fuel pump is advisable.

6. Service Tools & Equipment - Check out the necessary service tools and equipment you might require while solving and detecting the OBD errors for your car. These tools will do the correct analysis for you and will always come handy.

The check engine light may start illuminating due to the occurrence of P008A fault code. There may be an oxygen sensor code or codes indicating that the vehicle is running rich or lean. You may also experience some sort of misfire in the vehicle because of bad fuel conditions, start running roughly or may start experiencing an inability to accelerate.

Common Symptoms

• Less amount of power
• The output may be limited
• An unusual throttle response
• Decrease in the amount of fuel economy
• The emissions may start increasing
• Sluggish
• Noise may start coming from the car engine
• Hard start
• Smoke may start emitting from the engine on start-up

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

• You must check the diagnostic data as well as the freeze frame so that you become sure that there is no P1250 code that would mean the issue was low or no fuel and not a sensor malfunction
• Then the low side fuel pressure sensor should be replaced and then you must clear the fault codes. If you want to determine the code if it is gone or not, then the rerunning of the diagnostics is needed
• It is essential to wait to run diagnostics or do any replacement of other fuel system components like fuel filter, pump control module, or the fuel pump until the diagnostics on the low-side sensor

There is no need to get strained if your OBD Code is still flashing up. Check out our superior variety of Engine Control Module, Fuel Filter, Fuel System and many more. Now all your problems would vanish within no time.

• The technician should be completely sure that the car should not run out of gas when the code is created
• A scanner should be used by the technician as it would help in capturing freeze frame data and all related codes
• The sensor should be checked and the pressure should be measured in the supply lines which indicates if the sensor is bad
