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

\u2022 The PCM performs verification as to whether a condition in which A\/F (air\/fuel ratio) detection is not implemented due to poor A\/F sensor activation by a decrease in A\/F sensor performance or other malfunction has occurred. A DTC is stored if the A\/F sensor cannot implement feedback (non-active condition (resistance value is specified value or more)) for a continuous 35 s or more<\/span> under the condition in which the A\/F sensor heater control has been normally implemented. However, under a condition prior to the A\/F sensor performing activation (such as ignition switched off), and if there is an open\/short circuit (P2251:00) between the A\/F sensor terminal D and PCM terminal 1S (COM terminal), or an open\/short circuit (P2243:00) between A\/F sensor terminal F and PCM terminal 1T (B+ terminal), A\/F sensor activation determination is not performed and A\/F sensor non-activation (P0134:00) is determined. In addition, if a temporary malfunction is determined in the previous drive cycle because poor A\/F sensor activation was determined at the second drive cycle, DTCs are established for each malfunction determination even if the PCM determined a COM open circuit (P2251:00 temporary malfunction) or a B+ open circuit (P2243:00 temporary malfunction) in the previous drive cycle.<\/p>\n\n\n\n

Repeatability Verification Procedure<\/p>\n

1. Warm up the engine to allow the engine coolant temperature to reach 80 \u00b0C {176 \u00b0F} or more<\/span>.<\/div>\n
2. Start the engine and leave it idling for 1 min<\/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
3. 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
