0.04-inch Diagnosis
• Perform the diagnosis only once in 856 seconds or more after starting the engine, at a constant speed of
32 km/h (20 MPH) or more.
• Pay attention to the fuel temperature and fuel level.
0.02-inch Diagnosis
• Perform the diagnosis 125 seconds or more at a constant engine speed of 50 km/h (31 MPH) or higher to
judge as NG or OK.
• If judgement cannot be made, repeat the diagnosis.
• Pay attention to the fuel level.
