NOTE: For the diagnostic procedure, refer to DTC P014C. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P014C A/F / O2 SENSOR SLOW RESPONSE - RICH TO LEAN BANK 1 SENSOR 1 1. OUTLINE OF DIAGNOSIS Detect the slow response of front oxygen (A/F) sensor. For diagnosis, detect the trouble by processing the λ waveform in normal driving without forcibly changing the target air fuel ratio. 2. COMPONENT DESCRIPTION
3. EXECUTION CONDITION
4. GENERAL DRIVING CYCLE Perform diagnosis only once in a city driving including normal acceleration and deceleration. 5. DIAGNOSTIC METHOD 1 Detect the malfunction depending on the average value of time necessary for λ to inverse the air fuel ratio from “Lean > Rich > Lean” to “Rich > Lean > Rich”. Judge as NG when the following conditions are established.
Time Needed for Diagnosis: 70000 ms Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. 6. DIAGNOSTIC METHOD 2 Detect the malfunction by calculating the average amplitude of λ. Judge as NG when the following conditions are established.
Time Needed for Diagnosis: 70000 ms Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
Monitor (if equipped)
To clean the audio/navigation monitor,
wipe it with a silicone cloth or with a soft
cloth. If the monitor is extremely dirty,
clean it with a soft cloth moistened with
neutral detergent then carefully wipe off
any remaining detergent.
CAUTION
Do not spray neutral detergent
