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

\u2022 With an open circuit in the supply voltage line and a condition in which the supply voltage to PCM terminal 1T continues to be supplied, the PCM determines an open circuit in the wiring harness between the A\/F sensor and the PCM and stores a DTC.<\/div>\n



\n<\/a><\/p>\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>.<\/div>\n
