connector of the wire side.
Connection: White/red (+) – Green/orange (–)
Standard:
Is there within 4.75 – 5.25 V?
YES
NO
3. Bank Angle Sensor Input Voltage Line Open
Circuit Inspection
Turn the ignition switch OFF.
Disconnect the ECM 33P connector.
Check the continuities between the ECM 33P and
bank angle sensor 3P connectors.

TOOL:
Test probe
Are there continuities?
YES
NO
4. Bank Angle Sensor Output Line Open Circuit
Inspection
Turn the ignition switch OFF.
