What is the 230 code on a Chevy Silverado?
What is the 230 code on a Chevy Silverado?
the 230 is a fuel pump relay control code which is related to the other 2 codes you have of a wire issue to the FPCM or a bad FPCM The engine control module (ECM) sends the fuel enable signal to the fuel pump control module (FPCM). The control module monitors the voltage on the fuel pump relay control circuit.
What is the p025a code on a fuel pump?
P025A Fuel Pump Module Control Circuit/Open code is set when the ECM monitors a general malfunction or an open circuit within the Fuel Pump Module or it’s circuit (s). It is one of four related codes, which are P025A, P025B, P025C, and P025D.
Where does the fuel enable signal go on a Chevy Silverado?
The engine control module (ECM) sends the fuel enable signal to the fuel pump control module (FPCM). The control module monitors the voltage on the fuel pump relay control circuit.
What are the symptoms of a p0230 DTC?
If the PCM sees a voltage other than what is expected, P0230 may be set. Symptoms of a P0230 DTC may include: MIL (malfunction indicator lamp) illumination Fuel pump runs all the time with ignition on Potential causes of a P0230 code include: Short to battery voltage on control circuit Harness chafing causing one of above conditions

What causes the ECM to activate the p025a code?
The ECM activates P025A and associated codes when it monitors one or multiples conditions outside a specific electrical range within the Fuel Pump Control Module or it’s circuit. This can be caused by either a mechanical or an electrical problem.
