FOR DTC P1326 (PI2101Y/Z)

 NOTICE
This bulletin has been revised to include additional information. New/revised sections of this
bulletin are indicated by a black bar in the margin area.
This bulletin provides information related to the Technical Service Bulletin previously published in (PI2101)
titled “Knock Sensor Detection System - ECU Logic Improvement” for 2011MY Sorento (XMa) vehicles
equipped with Theta 2.4L MPI engine, produced from October 24, 2009 through June 24, 2011. Specifically,
this bulletin provides instructions on which procedures to follow if, after installation of the KSDS, any one of
the subject vehicles below return to the dealer with Diagnostic Trouble Code (DTC) P1326 (Knock Signal
Range/Performance).
If DTC P1326 is present, first perform the bearing clearance inspection with the Engine Bearing Clearance
Tester device (SST KQ231-2T110QQK). This device checks the rod bearing clearance by placing air and
vacuum into the cylinder block. Measure the bearing clearance and follow the instructions in this bulletin.
Refer to the flow chart found on pages 2-4, then follow the appropriate procedure as outlined in this bulletin.
Before conducting the procedure, verify the vehicle is included in the list of affected VINs.
A Vehicle Diagnosis Number (VDN) must be created with or without DTC P1326, after scanning for DTCs, prior
to performing PI2101Y/Z. If a VDN is not created, Warranty claim submission issues WILL occur.
