4 CHECK HARNESS AND CONNECTOR(A/F SENSOR−ECM, A/F SENSOR−A/F
SENSOR HEATER RELAY)
(a) Check the harness and the connectors between the ECM
and the A/F sensor.
(1) Disconnect the A34 A/F sensor connector.
(2) Disconnect the E12 ECM connector.
(3) Check the resistance between the wire harness
side connectors.
