1. Check the relay coupler CN23 of the fuel
sensor for disconnection. (Fig.29)
2. Measuring the voltage of the fuel sensor
coupler (Fig.30)
• Disconnect the coupler CN23.
• Key switch: ON
12 V
Other than 12 V : Measure the voltage of
3. Continuity check
(1) Measure the voltage between the sensor
coupler CN23-(3) and CN23-(1).
(2) Measure the voltage between the sensor
coupler CN23-(3) and body earth.
4. Continuity check (Fig.31)
Key switch: OFF
• Disconnect the meter coupler CN1 and CN2.
(1) Check for continuity between the sensor
coupler CN23-(2) and meter coupler CN1-
(11).
(2) Check for continuity between the sensor
coupler CN23-(3) and meter coupler CN2-
