How do you know if your transmission speed sensor is going out?
Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on.

How many ohms should a speed sensor read?
between 1,000 and 2,500 ohmsThe typical reading for a passive wheel speed sensor is between 1,000 and 2,500 ohms. This is a normal range for all passive sensors. The specification for active sensors is between 1,000 and 2,500 ohms.
How do I know if my speed sensor is working?
Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor's wire coupling. Using the multimeter's voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.
What happens when a speed sensor is faulty?
A faulty speed sensor can prevent a vehicle from shifting. This is important because the speedometer has to be calibrated in order for the transmission ECU to know when and how much to shift, so a faulty speed sensor could cause a discrepancy between what the computers are reading and what is going on mechanically.
What happens when a transmission sensor goes bad?
The Transmission Range Sensor tells the PCM the position of the transmission shifter. The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
Can you clean a transmission speed sensor?
In this case, the sensor may not have to be replaced as the sensor can be cleaned off. Yet, only a mechanic should make that determination because there may be damage to the electrical part of the sensor. Normally, the transmission speed sensor is diagnosed with a scan tool which is read by a mechanic.
How does a 3 wire speed sensor work?
A three-wire sensor has 3 wires present. Two power wires and one load wire. The power wires will connect to a power supply and the remaining wire to some type of load. The load is a device that is being controlled by the sensor.

How does a transmission speed sensor work?
The speed sensor detects a gear or target wheel in the transmission and generates an electric digital signal proportional to the speed of rotation. The transmission controls use this information to modify various transmission functions such as shift points and perform diagnostic tests.

What is the difference between an input and output speed sensor?
The first sensor, referred to as the input sensor, monitors the speed of the transmission's input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
