DTC Confirmation Procedure

WARNING:

If you do not select a suitable route and take proper precautions when performing a road test, an accident can occur.

- Select a level road with no traffic to minimize the risk of accident.
- Perform the test extremely carefully.
- Perform the road test using 2 persons, a driver and an assistant.

NOTE:

- If other DTC than P0722 is newly detected during this "DTC Confirmation Procedure", troubleshoot the newly detected DTC in first.
- Confirm that the following conditions are met in this procedure.

- Battery voltage > 10.5 V

1) Drive vehicle at more than 20 km/h (12 mile/h) for 10 sec.

DTC Troubleshooting


1. Was "CVT System Check" performed?
YES
Go to Step 2.
NO
Go to CVT System Check CVT System Check.
2. Secondary pulley speed sensor power supply circuit check
Confirm that ignition mode of keyless push start system is in "OFF".
Disconnect "C45" connector.
Check for proper terminal connection to "C45" connector.
If connections are OK, push engine switch to change ignition mode to "ON".
Check that "A1" circuit is battery voltage.
Is it in good condition?
YES
Go to Step 3.
NO
Repair or replace defective wire harness.
3. Secondary pulley speed sensor signal circuit and ground circuit check
Push engine switch to change ignition mode to "OFF".
Disconnect "E19" and "E20" connectors.
Check for proper terminal connection to "E19" and "E20" connectors.
If connections are OK, check the following points.
Resistance of "B2" and "C1" circuits: less than 1
Resistance between "B2" circuit and ground: infinity
Resistance between "B2" circuit terminal and each terminal at "C45" connector: infinity
Resistance between "C1" circuit terminal and each terminal at "C45" connector: infinity
Voltage of "B2" and "C1" circuits: 0 - 1 V (with ignition mode of keyless push start system in "ON")
Are they in good condition?
YES
Go to Step 4.
NO
Repair or replace defective wire harness.
4. Secondary pulley speed sensor check
Check secondary pulley speed sensor. Primary Pulley Speed Sensor and Secondary Pulley Speed Sensor Inspection
Is it in good condition?
YES
Substitute a known-good TCM and recheck DTC. Service and Repair
NO
Replace secondary pulley speed sensor. Secondary Pulley Speed Sensor Removal and Installation
