Function Explanation (DTC Detection Outline)

•  The PCM detects the oxygen concentration in the exhaust gas from the A/F sensor signal and performs fuel injection amount feedback to maintain the optimum air/fuel ratio. If a condition in which the feedback correction amount is large (fuel injection amount being increased) continues for the specified time, a feedback correction amount malfunction is determined, and a DTC is stored. The feedback correction amount has a “Fuel feedback correction amount” for the air/fuel ratio and a “Fuel learning correction amount” for fuel injector deterioration over time.
•  “Fuel feedback correction amount (SHRTFT1)” and “Fuel learning correction amount (LONGFT1)” can be verified from the M-MDS PID item.
1.  Sum of fuel feedback correction amount (SHRTFT1) and fuel learning correction amount (LONGFT1) is specified value (30%) or more, and 10 s or more have elapsed with fuel learning correction amount (LONGFT1) at specified value (15%) or more.
