DTC Detecting Condition and Trouble Area
ECT sensor value is less than 10 °C (50 °F) while engine is running under
more than specified engine load (more than 1000 rpm) after 2 to 1116 min.
(depending on ECT at engine start) elapsed from engine start.
(2 driving cycle detection logic, monitoring once per driving cycle)
DTC Confirmation Procedure
WARNING
!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.
NOTE
Check to make sure that the 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)
• Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
• The following DTCs are not detected: DTCs related to MAF sensor, ECT sensor (other than P0116),
IAT sensor and barometric pressure sensor
1) With ignition switch OFF, connect scan tool.
2) Turn ON ignition switch, clear DTC.
3) Drive vehicle more than 40 mph (65 km/h) for more than 12 minutes.
4) Stop vehicle.
5) Check DTC and pending DTC.
