Judgment Value
JUDGMENT VALUE
| Malfunction Criteria | Threshold Value |
|---|---|
| Engine oil temperature | < 50 °C (122 °F) |
| After engine start oil temperature sensor characteristic diagnosis timer. | ≥ Judgment value for after engine start oil temperature sensor characteristic diagnosis timer |
After engine start oil temperature sensor characteristic diagnosis timer (timer for diagnosis).
- Timer stop at fuel cut
- During the driving conditions except a) above, timer counts up as follows.
64 ms + TOILCNT ms (when at 64 ms)
Where, TOILCNT is determined as follows,
TOILCNT = 0 at idle switch ON
For TOILCNT at Idle switch off, refer to the following table.
| Vehicle speed km/h (MPH) | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| 0 (0) | 8 (5) | 16 (9.9) | 24 (14.9) | 32 (19.9) | 40 (24.9) | 48 (29.8) | 56 (34.8) | ||
| Temperature °C (°F) |
-40 (-40) | 0 ms | 32 ms | 76 ms | 130 ms | 149 ms | 171 ms | 176 ms | 181 ms |
| -30 (-22) | 0 ms | 93 ms | 121 ms | 157 ms | 170 ms | 184 ms | 193 ms | 203 ms | |
| -20 (-4) | 0 ms | 123 ms | 148 ms | 184 ms | 193 ms | 204 ms | 214 ms | 226 ms | |

| 0 (32) | 0 ms | 187 ms | 212 ms | 243 ms | 252 ms | 262 ms | 266 ms | 270 ms | |
After engine start oil temperature characteristic diagnosis timer judgment value (t).
t = 3600000 ms - 60000 ms x Ti (t ≥ 2400000)
Ti = The lowest coolant temperature after starting the engine.
Time Needed for Diagnosis: Less than 1 second
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles.
- Normality Judgment
Judge as OK and clear the NG if the following conditions are established.
