D8: Check Sensor Resistance

Reconnect PI026 and PI027
Measure the bank A sensor coil resistance between EM013/018 and EM013/027
Repeat for Bank B sensor, between EM013/017 and EM013/027

- Is the resistance 500 k ohms to 620 k ohms?
Yes
GO to D9 D9: End
No
Renew the sensor(s) and test the system for normal operation.
