DTC DESCRIPTION P0443 - EVAP SYSTEM PURGE CONTROL VALVE A CIRCUIT

Description:	This DTC sets when the signal moves outside the minimum or maximum limit for the commanded state.
Possible Causes:	VPWR circuit open EVAPCP circuit open EVAPCP circuit short to ground EVAPCP circuit short to voltage Damaged EVAP purge valve
Diagnostic Aids:	To verify normal function, monitor the EVMV PID or EVAPCP PID and the signal voltage (PCM control side). With the valve closed, the EVMV indicates 0 mA (0% duty cycle for EVAPCP) and voltage approximately equal to battery voltage. When the valve is commanded fully open, EVMV indicates 1, 000 mA (100% duty cycle for EVAPCP) and a voltage drop of 3 volts minimum is normal.
