(a) Turn the ignition switch to "OFF" position.
(b) Disconnect vehicle speed sensor wiring harness connector
EO21.
(c) Turn the ignition switch to "ON" position.
(d) Measure voltage between vehicle speed sensor harness
connector EO21 terminal No.1 and a reliable ground.
Standard Voltage: 11-14 V
(e) Connect vehicle speed sensor harness connector EO21.
Is the value specified value?
Check whether there is a short circuit between
No
the vehicle speed sensor terminal No.1 and
the main relay terminal No.87. Repair the
faulty part.
(a) Turn the ignition switch to "OFF" position.
(b) Disconnect vehicle speed sensor wiring harness connector
EO21.
(c) Measure resistance between vehicle speed sensor harness
connector EO21 terminal No.2 and a reliable ground. Check
whether the circuit is short to ground.
Standard Resistance: Less than 1 Ω
Is the value specified value
Check whether there is an open circuit
No
between the vehicle speed sensor terminal
No.2 and a reliable ground. Repair the faulty
part.
Go to step 8
Next
(a) Check whether ECM power supply circuit is normal.
(b) Check whether ECM ground circuit is normal.
