L1: Check Vehicle Speed Sensor Signal
With the ignition key in the OFF position, connect a voltmeter between the Pink/Blue wire at the instrument cluster connector C3 and the Black/Red wire at the instrument cluster connector C2. See WIRING DIAGRAMS . Place the voltmeter in the AC volts position and drive the vehicle at the speeds indicated below and chart their corresponding voltages. See SPEED-TO-VOLTAGE COMPARISON .
SPEED-TO-VOLTAGE COMPARISON
| Speed MPH (KM/H) | Approximate AC Voltage (Volts) |
|---|---|
| 0 (0) | 0 |
| 5 (8) | 0.5 |
| 10 (16) | 1.0 |
| 15 (24) | 1.6 |
| 20 (32) | 2.0 |
| 25 (40) | 2.4 |
| 30 (48) | 2.8 |
| 35 (56) | 3.1 |
| 40 (64) | 3.4 |
| 45 (72) | 3.6 |
| 50 (80) | 3.9 |
| 55 (88) | 4.2 |
| 60 (96) | 4.4 |
Are the voltages correct? If yes, replace the instrument cluster. If no, go to the next step.
