Diagnosis Procedure
1.CHECK CONNECTOR
2.CHECK HARNESS FOR OPEN CIRCUIT

3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the A/C auto amp. Refer to the following.
AV branch line circuit
STRG branch line circuitP0443 evap canister purge volume control solenoid valve
Description
The EVAP canister purge volume control solenoid valve is used 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
