P0443 - EVAPORATIVE EMISSION SYSTEM PURGE CONTROL VALVE CIRCUIT - DTC CHART
| Description: This DTC sets when the signal moves outside the minimum or maximum limit for the commanded state. | |||
Possible Causes:
|
|||
| 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. | |||
