Troubleshooting
Operating Condition
In manual or spray mode
Cause/Solution
Visually check wire connections.
Check the resistance across the
sensor, while moving a strong mag-
net in front of the sensor. The reading
should be less than 0.1 ohms when a
magnet is in front of the sensor and
have no reading when there is no
magnet.
Check position of sensor.
Replace sensor if faulty. See Ser-
vice, page 91.
Replace circuit board. See Service,
page 86.
