MONITOR DESCRIPTION
This DTC indicates a problem with the shift lever position sensor, transmission control switch or wire harness of their circuits.
The shift lever position sensor sends a signal to the ECM according to the shift lever position (P, R, N or D).
If the ECM detects a malfunction in the signal of the shift position sensor, it is suspected that a sensor or related component is malfunctioning. The ECM will then illuminate the MIL and store a DTC.
CONFIRMATION DRIVING PATTERN
- HINT:
- ·
After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
·When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for 2 minutes or more.
Wait with the shift lever in each position (P, R, N or D) for 2 seconds or more each with the ignition switch ON. [*1]
Wait for 2 seconds or more with the shift lever in M. [*2]
- HINT:
-
[*1] and [*2]: Normal judgment procedure.
-
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P070562.
Check the DTC judgment result.
| GTS Display | Description |
|---|---|
| NORMAL | ·
DTC judgment completed ·
System normal |
| ABNORMAL | ·
DTC judgment completed ·
System abnormal |
| INCOMPLETE | ·
DTC judgment not completed ·
Perform driving pattern after confirming DTC enabling conditions |
| N/A | ·
Unable to perform DTC judgment ·
Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit |
- HINT:
- ·
If the judgment result shows NORMAL, the system is normal.
·If the judgment result shows ABNORMAL, the system has a malfunction.
·If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
- NOTICE:
- ·
Perform the universal trip to clear permanent DTCs.
·Perform registration and/or initialization when parts related to the continuously variable transaxle system are replaced.
·Check that no DTCs are stored after performing initialization.
·Inspect the fuses for circuits related to this system before performing the following inspection procedure.
