DTC P0741 TROUBLESHOOTING CHART

Step	Action	YES	NO
1	Was "CVT System Check" performed?	Go to Step 2.	Go to CVT SYSTEM CHECK .
2	DTC check of ECM Check DTC of ECM. See DTC CHECK Is there any DTC(s)?	Go to troubleshooting for applicable DTC.	Go to Step 3.
3	Primary pulley speed sensor and its circuit check Check primary pulley speed sensor and its circuit according to Step 3 through 4 of DTC P0717 . Are they in good condition?	Go to Step 4.	Repair or replace defective parts.
