| TERMINAL NO. | ITEM | CONDITION | DATA* |
|---|---|---|---|
| 27 | Air flow meter | Engine is running. — Idle speed | 1.6V |
| 27 | Air flow meter | Engine is running. — Engine speed is approximately 2,500 rpm. | 2.2V; Output voltage varies with engine revolution. |
| 28 | Engine temperature sensor | Engine is running. | 1.0 - 5.0V; Output voltage varies with engine coolant temperature. |
| 29 | Exhaust gas sensor | Engine is running. — After warming up sufficiently | 0 - Approximately 1.0V |
| 38 | Throttle sensor | Ignition switch "ON" | 0.5 - 4.0V; Output voltage varies with the throttle valve opening angle. |
| 41, 51 | Crank angle sensor (Reference signal) | Engine is running. Do not run engine at high speed under no-load. | 0.6 - 0.8V |
| 42, 52 | Crank angle sensor (Position signal) | Engine is running. Do not run engine at high speed under no-load. | 2.0 - 2.6V |
| 43 | Start signal | Cranking | 8 - 12V |
| 44 | Neutral switch & Inhibitor switch | Ignition switch "ON" — Neutral/Parking | 0V |
| 44 | Neutral switch & Inhibitor switch | Ignition switch "ON" — Except the above gear position | 4 - 5V |
| 45 | Ignition switch | Ignition switch "OFF" | 0V |
| 45 | Ignition switch | Ignition switch "ON" | BATTERY VOLTAGE (11 - 14V) |
