P000200/P000201 Espar fault code

Modified on Mon, 29 Sep at 4:44 AM

The P000200 fault code indicates that the fuel pump is experiencing power interruptions. Usually appears when the pump is not wired correctly or the fuel pump wires are not fully seated in the plug. It can also be related to the heater power supply. 


The P000201 fault code indicates that the fuel pump has been shorted. You should apply 12V power directly to the fuel pump pins in 1-second intervals. If the fuel pump is ticking, it should still be operational, if not, it should be replaced.
