Code P0443 2010 Nissan Pathfinder Description
The EVAP canister purge volume control solenoid valve uses an ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
The Diagnostic Trouble Code (DTC) will set when the canister purge flow is detected during the specified driving conditions, even when the EVAP canister purge volume control solenoid valve is completely closed.
What are the Possible Causes of the DTC P0443 2010 Nissan Pathfinder?
- Faulty EVAP Canister Purge Volume Control Solenoid Valve
- EVAP Canister Purge Volume Control Solenoid Valve harness is open or shorted
- EVAP Canister Purge Volume Control Solenoid Valve circuit poor electrical connection
- Faulty EVAP Control System Pressure Sensor
