Possible causes

– Faulty Input Speed Sensor
– Input Speed Sensor harness is open or shorted
– Input Speed Sensor circuit poor electrical connection

When is the code detected?

The Transmission Control Module (TCM) has detected a correlation error between the two Input Speed Sensor signals.

Symptoms

– Engine Light ON (or Service Engine Soon Warning Light)

P2767 JEEP Description

The Input Speed Sensor 2 is one of the two hall effect speed sensors that are used by the Transmission Control Module (TCM) to calculate the transmissions turbine speed. Since the turbine speed could not be measured directly, two of the drive elements are measured. Two input speed sensors are required because both elements are not active in all gears.
