Where are the speed sensors located on a jeep?
Signals from the speed sensors, N2 and N3, (6, 8) are recorded in the transmission control module (TCM), together with the wheel and engine speeds and other information, and are processed into an input signal for electronic control. Speed sensor N2 (6) records the speed of the front planetary rear annulus assembly (10).
How does the N2 sensor work in a jeep?
With the vehicle moving forward or reverse, N2 speed sensor reading will be greater than zero in all gears. Whenever the K1 clutch is applied (2nd, 3rd, and 4th) N2 will be equal to N3. There is no speed sensor internal to the transmission that directly measures input shaft speed.
