P1443 FORD, INFINITI, JAGUAR, LINCOLN, NISSAN, MERCEDEZ. MERCURY, SAAB: EVAPORATIVE EMISSION CONTROL SYSTEM CONTROL VALVE
The Evaporative Emissions Control System (EVAP) stores fuel vapors so that they cannot be released into the environment. It includes various sensors, switches, and valves controlled by the Engine Control Module (ECM).
On the other hand, you can locate the canister control vacuum check switch in the vacuum line. Specifically, it is between the canister purge solenoid and the purge control valve. This switch detects the vacuum signal to the purge control valve. It also provides an On/Off signal to the ECM. When no vacuum is supplied to the valve, the switch sends an On signal. At the moment the vacuum is supplied to the valve, the ECM receives an Off signal from the vacuum control switch.
The DTC P1443 OBDII code is a code used by the manufacturers’ Ford, Infiniti, Mercedes, and other vehicles to indicate that the PCM has found a fault in the EVAP system control valve.
