DATA MONITOR MODE DESCRIPTIONS
| Monitored Item | Description |
|---|---|
| ENG SPEED [rpm] | Indicates the engine speed computed from the REF signal (180° signal) of the camshaft position sensor. |

| COOLAN TEMP/S [°C] or [°F] | The engine coolant temperature (determined by the signal voltage of the engine coolant temperature sensor) is displayed. When the engine coolant temperature sensor is open or short-circuited, ECM enters fail-safe mode. The engine coolant temperature determined by the ECM is displayed. |
| H02S1 (B1) [V] | The signal voltage of the heated oxygen sensor 1 (front) is displayed. |

| H02S1 MNTR (B1) [RICH/LEAN] | Display of heated oxygen sensor 1 (front) signal during air-fuel ratio feedback control: RICH - means the mixture became "rich", and control is being affected toward a leaner mixture. LEAN - means the mixture became "lean", and control is being affected toward a rich mixture. After turning ON the ignition switch, RICH is displayed until air-fuel mixture ratio feedback control begins. When the air-fuel ratio feedback is clamped, the value just before the clamping is displayed continuously. |
| H02S2 MNTR (B1) [RICH/LEAN] | Display of heated oxygen sensor 2 (rear) signal: RICH - means the amount of oxygen after three way catalyst is relatively small. LEAN - means the amount of oxygen after three way catalyst is relatively large. When the engine is stopped, a certain value is indicated. |
