DTC Set Conditions

Check conditions are when barometric pressure is less than 11 psi (76 kPa). Judgement criteria is when 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 engine coolant temperature is 162°F (72° C) or greater during each of the 15 times of driving. Also, during each of the 15 times of driving, make sure that after engine has been started, the engine coolant temperature has increased to 41°F (23°C) or greater.
