Function Explanation (DTC Detection Outline)<\/p>\n

\u2022 The PCM detects the crankshaft rotation speed based on the crankshaft position sensor signal. If there is a small amount of fluctuation in crankshaft rotation speed due to the effect of combustion of each cylinder while the engine is rotating and a misfire occurs in any of the pistons, the crankshaft rotation speed will change suddenly. The PCM adds the number of changes in sudden rotation speed (misfire rate) to each specified crankshaft rotation speed, and if the misfire rate exceeds a certain value, a DTC is recorded.<\/p>\n\n\n\n

Repeatability Verification Procedure<\/p>\n

1. Drive the vehicle at a speed of 40 km\/h {25 mph} or more<\/span>.<\/div>\n
2. Shift to 3rd gear and rapidly accelerate the vehicle to 60 km\/h {37 mph}<\/span> (to execute misfire monitor).<\/div>\n
3. Release the accelerator pedal and decelerate the vehicle to 40 km\/h {25 mph}<\/span>.<\/div>\n
4. Repeat Step 1 to 3 operations above 5 times<\/span>.<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 Match the engine coolant temperature in the recorded freeze frame data\/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
5. Try to reproduce the malfunction by driving the vehicle for 5 min<\/span> based on the values in the freeze frame data\/snapshot data.<\/div>\n
