DTC Detecting Condition and Trouble Area
Difference of maximum IAT minus minimum IAT is less than specified value while
ECT is over 70 °C (158 °F) after 10 min from cold engine start (ECT is lower than
30°C (86 °F) at engine start).
(2 driving cycle detection logic)
DTC Confirmation Procedure
NOTE
Check to make sure that following conditions are satisfied when using this "DTC Confirmation
Procedure".
• Intake air temperature at engine start: –10 °C (14 °F) to 80 °C (176 °F)
• Intake air temperature: –10 °C (14 °F) to 70 °C (158 °F)
• Engine coolant temperature at engine start: less than 30 °C (86 °F)
• Engine coolant temperature: 70 °C (158 °F) or more
• Altitude (barometric pressure): 2500 m, 8200 ft or less (560 mmHg, 74.4 kPa or more)
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch, clear DTC using scan tool.
3) Start engine and warm up to normal operating temperature. (ECT approx. 90 – 95 °C, 194 – 203 °F)
4) Run engine at idle speed for 10 min. or more.
