PRE-RELEASE
DTC 22 AND 32 VEHICLE SPEED SENSOR
| DTC 22 AND 32 VEHICLE SPEED SENSOR |
DIAGNOSIS:
Disconnection or short circuit of vehicle speed sensor system.
TROUBLE SYMPTOM:
Cruise control cannot be set. (Cancelled immediately.)
WIRING DIAGRAM:
CHECK HARNESS BETWEEN BATTERY AND VEHICLE SPEED SENSOR.
Turn the ignition switch to OFF.Disconnect the harness connector from vehicle speed sensor.
Turn the ignition switch to ON.
Measure the voltage between vehicle speed sensor harness connector terminal and chassis ground.
Connector & terminal
(B17) No. 3 (+) — Chassis ground (−):
Is the voltage more than 10 V?
| Yes |
| No |
Check the harness for open or short between fuse and vehicle speed sensor.
CHECK HARNESS BETWEEN ECM AND VEHICLE SPEED SENSOR.
Turn the ignition switch to OFF.Disconnect the harness connector from ECM.
Measure the resistance between vehicle speed sensor harness connector terminal and ECM harness connector terminal.
Connector & terminal
(B17) No. 1 — (B135) No. 27:
Is the resistance less than 10 Ω?
| Yes |
| No |
Repair the harness.
CHECK HARNESS BETWEEN VEHICLE SPEED SENSOR AND ENGINE GROUND.
Turn the ignition switch to OFF.Measure the resistance between vehicle speed sensor harness connector terminal and engine ground.
Connector & terminal
(B17) No. 2 — Engine ground:
Is the resistance less than 10 Ω?
| Yes |
| No |
Repair the harness.
CHECK VEHICLE SPEED SENSOR.
Connect the harness connector to vehicle speed sensor.Lift-up the vehicle and support with rigid racks.
Drive the vehicle at speed greater than 20 km/h (12 MPH).

Warning
Measure the voltage between ECM harness connector terminal and chassis ground.
Connector & terminal
(B135) No. 27 (+) — Chassis ground (−):
Is the voltage less than 1 V ←→ more than 5 V?
| Yes |
Check the poor contact of ECM connector.
| No |
Replace the vehicle speed sensor.
