DTC Set Conditions

Check conditions are where barometric pressure is lower than 11 psi (76 kPa). Judgement criteria is where during 15 times of driving, the changes in the sensor output voltage should be 0.015 volt [equivalent to 0.06 psi (0.4 kPa)] or less. Make sure that the engine coolant temperature is 160°F (72°C) or higher during each of the 15 times of driving. Also, during each of the 15 times of driving, make sure that after the engine has been started, the engine coolant temperature has increased for 40°F (23°C) or higher.
