Green and Yellow/Red: If there is not continuity, replace the sensor; if there is continuity,
check the connector: if not OK, restore the cable harness; if OK, check, with key set to ON,
if there is voltage on Yellow/Red cable: if there is no voltage, restore the cable harness; if
there is, check the Yellow/Red cable ground insulation: If there is continuity with ground
connection, restore the cable harness; if OK, set the key to OFF and check the VEHICLE
