Check the intake air temperature sensor.
| *1 | Resistance kΩ | *2 | Temperature °C (°F) |
| *3 | Acceptable Range | - | - |
| *a | Component without harness connected ( Mass air flow meter) | - | - |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition 4 (THA) - 5 (E2) -20°C (-4°F) 12.5 to 16.9 kΩ 20°C (68°F) 2.19 to 2.67 kΩ 60°C (140°F) 0.50 to 0.68 kΩ
If the result is not as specified, replace the mass air flow meter.
