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 delayed response of rear oxygen sensor output for rich > lean. After the deceleration fuel cut has started, detect the trouble by calculating the time when the rear oxygen sensor output decreases to the predetermined 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 the diagnosis only once when the deceleration fuel cut is activated from a high and constant speed driving. 5. DIAGNOSTIC METHOD Detect the trouble by calculating the time from the beginning of the fuel cut to the beginning of the rear oxygen sensor voltage starting to drop.
Judge as NG when the following conditions are established.
Time Needed for Diagnosis: 5000 ms Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
