3-88 FUEL SYSTEM (DFI)
Speed Sensor (Service Code 24, 25)
Disconnect the speed sensor connector [A] and connect
the harness adapter [B] between the harness connector
and speed sensor connector.
Connect a digital meter to the harness adapter leads.
Special Tool - Throttle Sensor Setting Adapter:
Throttle Sensor Output Voltage
Connections to Sensor
Meter (+) → Y lead [C]
Meter (–) → BK lead [D]
Measure the sensor output voltage with the engine
stopped, and with the connector joined.
Turn the ignition switch ON.
Output Voltage at Sensor
If you can rotate the engine sprocket, the output voltage
will be raise.
If the reading is out of the range, check the speed sensor
(see Electrical System chapter) and the wiring to ECU
(see wiring diagram in this section).
If the reading, speed sensor and wiring are good, replace
About 0.05 ∼ 0.07 V DC
