DTC P0443 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE (CIRCUIT) - ECM Terminals and Reference Value / DTC Confirmation Procedure
EF & EC-7192prose procedureCG10, CGA3
ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and ground.
CAUTION
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a grond other than ECM terminals, such as the ground.
