How do I fix error code P0230?
What repairs can fix the P0230 code?
- Repairing or replacing the fuel pump fuse or fusible link, and replacing the fuel pump.
- Replacing the fuel pump relay.
- Replacing the fuel pump only.
What does fuel pump control circuit open mean?
P0627
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.
What is a fuel pump secondary circuit?
OBD-II Code Decreased engine performance is defined as a Fuel Pump Secondary Circuit High. The Fuel Pump enables the transfer of fuel from the fuel tank to the fuel injectors in the engine. The Fuel Pump is controlled by the engine computer (PCM) or the Fuel Pump Control Module (most newer vehicles).
What is the code for a fuel pump?
The trouble codes associated with a bad fuel pump are P0201, P0267, P0268, P0231, P0232, P0030, and P0087. Keep in mind the trouble codes will also depend on the make and model of your vehicle.
Where is fuel pump fuse?
In most cases the fuse box under the hood will contain both the fuel pump fuse and relay.
Where is the fuel pump control module?
The module is typically installed on or very close to the fuel pump, and in the early years of the component’s use, this practice led to a design fault. Manufacturers, including Ford, initially placed the module inside the vehicle immediately above the fuel pump, typically just beneath the floor pan.
Where is fuel pump relay?
The fuel pump relay is an electronic component that is found on virtually all vehicles equipped with an internal combustion engine. It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump.
What is fuel pump secondary circuit low?
Code P0230 is triggered by low voltage in the main power circuit of the fuel pump relay. The ECM monitors this voltage to see if it falls below a specified voltage.
Will a bad fuel pump give a code?
Bad Fuel Pump, Fuel Pressure Sensor Can Trigger ‘Check Engine’ Light, P0087 Code. The light is part of your vehicle’s on-board diagnostics (OBD) system and can indicate anything from a loose gas cap to a major repair like a catalytic converter.
What causes a p0230 fuel pump to malfunction?
Potential causes of a P0230 code include: 1 Short to ground on control circuit 2 Fuel pump control circuit open 3 Short to battery voltage on control circuit 4 Harness chafing causing one of above conditions 5 Bad relay 6 Bad PCM
What does the OBD code p0230 mean?
P0230 is a generic OBD-II code which indicates that the fuel pump primary circuit has a malfunction of the vehicle power to the fuel pump when it is commanded on or off What causes the P0230 code? The engine control module (ECM) detects the primary fuel pump circuit voltage as below specifications from the fuel pump relay to the ECM
What causes an OBD code for a GMC fuel pump?
Causes. Possible causes of OBD code P0230 GM. Potential causes of a P0230 GM code include: Short to ground on control circuit Fuel pump control circuit open Short to battery voltage on control circuit Harness chafing causing one of above conditions Bad relay Bad PCM.
What happens when the p0230 GM is deactivated?
The driver in the PCM is monitored for faults. When activated the driver or ground circuit voltage should be low. When deactivated the driver/ground potential voltage should be high or near battery voltage. If the PCM sees a voltage other than what is expected, P0230 GM may be set.
