Engine Control System

DTC 33
VEHICLE SPEED SENSOR 2






Diagnosis
- The Vehicle Speed Sensor 2 is not functioning.
- The harness connector between Engine Control Module (ECM) and Vehicle Speed Sensor 2 is short or open.

Trouble Symptom
- Erroneous idling.
- Engine stalls.
- Poor driving performance.

1. Check Vehicle Speed Sensor 2.
a. Remove Combination Meter.






b. Measure resistance between connector terminals of Combination Meter by rotating rotor of Speedometer cable hole with screwdriver.

Terminals / Specified Resistance:
No. 11 - No. 8 / 10 Ohms, maximum <--> 1 M-Ohm, minimum
(Four times per rotation)

2. Check harness connector between ECM and Vehicle Speed Sensor 2.
a. Turn Ignition Switch to "OFF".
b. Disconnect connector from ECM.






c. Measure resistance of harness connector between ECM and Combination Meter.

Connector & Terminal / Specified Resistance:
(E29) No. 4 - (i18) No. 8 / 10 Ohms, maximum






d. Measure resistance of harness connector between ECM and body to make sure that circuit does not short.

Connector & Terminal / Specified Resistance:
(E29) No. 4 - Body / 1 M-Ohm, minimum

3. Check ground circuit of Vehicle Speed Sensor 2.





- Measure resistance between Combination Meter and body.

Connector & Terminal / Specified Resistance:
(118) No. 8 - Body / 1 M-Ohm, minimum
