DTC Set Conditions

NOTE: This is only if engine coolant temperature is less than 32°F (0°C) when starting.

Check conditions are when 8 minutes or more have passed after starting the engine, engine coolant temperature is more than 113°F (45°C), intake air temperature is more than 32°F (0°C) and volumetric efficiency is 30-45 percent. Judgment criteria is when manifold differential pressure sensor output voltage has continued to be more than 4.6 volts, corresponding to an absolute pressure of 17 psi (118 kPa) or more for 2 seconds or manifold differential pressure sensor output voltage has continued to be less than 0.1 volt, corresponding to an absolute pressure of 0.3 psi (2.4 kPa) or less, for 2 seconds.

NOTE: This is only if engine coolant temperature is 32°F (0°C) or more when starting.

Check conditions are when 8 minutes or more have passed after starting the engine, engine coolant temperature is more than 113°F (45°C), intake air temperature is more than 32°F (0°C) and volumetric efficiency is less than 30 percent. Judgment criteria is when manifold differential pressure sensor output voltage has continued to be more than 4.2 volts, corresponding to an absolute pressure of 16 psi (108 kPa) or more, for 2 seconds.

NOTE: This is only if engine coolant temperature is 32°F (0°C) or more when starting.

Check conditions are when 8 minutes or more have passed after starting the engine, engine coolant temperature is more than 113°F (45°C), intake air temperature is more than 32°F (0°C) and volumetric efficiency is more than 70 percent. Judgment criteria is when manifold differential pressure sensor output voltage has continued to be less than 1.8 volts, corresponding to an absolute pressure of 4.6 psi (46 kPa) or less, for 2 seconds.
