DTC P1E66 Chevrolet

Cause and Solution

Vehicle speed has reached at least 15 km h (9 mph) from a stop more three times during the same ignition cycle. During the time the vehicle is stationary; the yaw rate signal value is more than 7 deg sec for 2 seconds.When vehicle speed is more than 25 km h (16 mph) in a turn the difference between the yaw rate, steering angle, lateral acceleration, and wheel speed sensor values are not correlated three consecutive times.Yaw rate changes greater than 20 deg sec in 6 ms four times in one second.Combination sensor fails an internal self test.Ignition voltage to the combination sensor is less than 9.5 volts.Communication is lost between the EBCM and the combination sensor.
