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 lean > rich. After the deceleration fuel cut has completed, detect the trouble by calculating the time when the rear oxygen sensor output increases 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 diagnosis only once when recovering from the deceleration fuel cut continued for more than predetermined time with the rear oxygen sensor warmed up sufficiently. 5. DIAGNOSTIC METHOD Detect the trouble by calculating the time from the completion of the fuel cut to the beginning of the rear oxygen sensor voltage starting to rise.
Judge as NG when the following conditions are established.
Time Needed for Diagnosis: 3750 time(s) - 32 ms Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
Inspection
1. Check that the engine oil cooler, engine oil cooler pipe, and oil cooler connector do not have deformation, cracks or damage.2. Make sure the engine oil cooler hoses are not cracked, damaged or loose.3. Blow with compressed air to make sure the coolant passages are not clogged.4. Check that the o ...
