CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P1585

DTC Code DTC Name
P1585 Acceleration Sensor Circuit

DESCRIPTION

The ECM determines the vehicle inclination based on a signal from the yaw rate sensor.

Tech Tips

If CAN communication DTCs are output, perform troubleshooting for those DTCs first.
