NOTE: For the diagnostic procedure, refer to DTC P013A. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P013A O2 SENSOR SLOW RESPONSE - RICH TO LEAN BANK 1 SENSOR 2 1. OUTLINE OF DIAGNOSIS Detect the slow response of lean > rich for rear oxygen sensor output. After the deceleration fuel cut has occurred, detect the trouble by calculating the time when the rear oxygen sensor output passes through the predetermined range of voltages. Judge as NG when the response time is larger than the threshold value. 2. COMPONENT DESCRIPTION
3. EXECUTION CONDITION
4. GENERAL DRIVING CYCLE Perform diagnosis only once after recovering from a deceleration fuel cut continued for more than predetermined time. 5. DIAGNOSTIC METHOD Detect the trouble by calculating the response time of the rear oxygen sensor after fuel cut.
Judge as NG when the following conditions are established.
Time Needed for Diagnosis: 4000 ms Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
