How does the EVAP canister purge volume control solenoid valve work?
The Evaporative Emission System ( EVAP) canister purge volume control solenoid valve uses a 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 Engine Control Module ( ECM ).
Why is the p0443 canister purge valve malfunction?
When the solenoid is activated, the ECM should see the ground voltage pulled low, close to zero. If the ECM doesn’t see these expected voltages, or senses an open in the circuit, this code is set.
