Typical Malfunction Thresholds
WARNING: This page is about a different variant/trim than selected.
JUDGMENT BY SIMULATED ENGINE COOLANT TEMPERATURE
| Duration that both of the following conditions are met | 5 seconds or more |
| (a) Estimated engine coolant temperature | 75°C (167°F) or higher |
| (b) Engine coolant temperature sensor output | Less than 75°C (167°F) |
JUDGMENT BY ENGINE COOLANT TEMPERATURE AND NO. 2 ENGINE COOLANT TEMPERATURE CHANGES (W/ GRILLE SHUTTER SYSTEM)
| Engine coolant temperature change speed | Less than -0.4°C/sec (-0.72°F/sec), or higher than 0.15°C/sec (0.27°F/sec) |
| Engine coolant temperature | Less than 75°C (167°F) |
| Grade of engine coolant temperature - No. 2 engine coolant temperature | Higher than -0.1°C/sec (-0.18°F/sec), and less than 0.1°C/sec (0.18°F/sec) |
| Absolute engine coolant temperature - No. 2 engine coolant temperature | Less than 6.6°C (11.8°F) |
JUDGMENT BY ENGINE COOLANT TEMPERATURE CHANGE AT HIGH VEHICLE SPEED (W/O GRILLE SHUTTER SYSTEM)
| Malfunction counter | 3 times or more |
| Malfunction counter is incremented when following conditions are met | A and B |
| A. Average engine coolant temperature change (vary with current engine coolant temperature, estimated ambient air temperature, intake air mass and vehicle speed) | Less than 0.01°C/sec (0.018°F/sec) |
| B. Engine coolant temperature is satisfied throughout this period | Less than 75°C (167°F) |
