What does code P062A mean?
Decreased engine performance
OBD-II Code Decreased engine performance is defined as a Fuel Pump “A” Control Circuit Range/Performance. The Fuel Pump enables the transfer of fuel from the tank to the fuel injectors. If the engine control module (PCM) detects the fuel pump is not operating properly, the PCM will set code P062A.
What causes P0002 code?
P0002 is a generic OBD-II code indicating an issue with the engine control module (ECM) reading signals from your fuel pressure regulator on your fuel injection rail mounted to your engine.
What does code P023F mean?
The Fuel Pump is controlled by the engine computer (PCM) or the Fuel Pump Control Module (most newer vehicles). When the Ignition is turned on, the PCM or Fuel Pump Control Module will activate the fuel pump. If the PCM detects an incorrect signal to or from the fuel pump, it will set code P023F.
What does code P025A mean?
Fuel Pump Module Control Circuit/Open
OBD-II Code P025A is defined as a Fuel Pump Module Control Circuit/Open. The engine computer (PCM) supplies voltage to the Fuel Pump Control Module. If there is a problem with the voltage supply to the Fuel Pump Module, code P025A is set.
How do you fix P0002?
- Use a scan tool to clear all codes and test the system to see if P0002 is still present.
- If the code is not present, check the fuel pressure to make sure it’s within specification.
- If P0002 is still present, check for corroded or loose connections in the power supply to the fuel pressure regulator.
Where is the fuel volume regulator?
Fuel pressure and volume are regulated by control valves located on the pump. The fuel volume control valve (otherwise known as a fuel volume control regulator) regulates the volume of fuel produced by the injection pump.
What is code P0004?
P0004 is a generic OBD-II code indicating an issue with the engine control module (ECM) not reading signals from your fuel shut-off on your fuel injection rail mounted to your engine.
What is fuel pump secondary circuit failure?
Code P0232 is triggered when voltage in the fuel pump secondary circuit is shorted to vehicle power through the relay. The ECM monitors this voltage to see if it stays on after the key is turned off. The most common failure is a relay stuck to the On position internally.
What does fuel pump circuit open mean?
OBD-II Code P0627 is defined as a Fuel Pump “A” Control Circuit/Open. The Fuel Pump enables the transfer of fuel from the tank to the fuel injectors. If the engine control module (PCM) detects the fuel pump is not operating properly, the PCM will set code P0627.
