How do you test a gearbox sensor?
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.
Is there a way to test the Speedo sensor?
I was told that the way to test these sensors was to supply +12v to pin 1, -12v to pin 2 and put your multimeter negative lead to pin 2, positive to pin 3 and gently turn the gear. As you slowly turn it the reading on the meter should fluctuate between 12v and 0v on the dc range.
How to test the speed sensor ( gearbox )?
You can remove the cluster and connect the DMM to the signal wire 5517 and ground 0058. Set the DMM on volts, it should be between 8V and 10 V. Also read the frequency. You can drive normally without cluster, to do the necessary tests, but be careful in traffic, possibly ask someone to assist you.
What causes the Odo to work on a Speedo?
Also shorting pin 3 and 1 quickly and intermittently causes the speedo to read a reading and the odo to work. I was told that the way to test these sensors was to supply +12v to pin 1, -12v to pin 2 and put your multimeter negative lead to pin 2, positive to pin 3 and gently turn the gear.
Why is my Speedo not working on my car?
The Sensor is not connected to the BSI,its connected to the Engine management ECU which transmits a multiplexed ( Pulsed signal to the BSI corresponding to the vehicle speed). Did you disconnect the battery when you were installing tow bar or accidently shorted something ? Try testing sensor and see what pulsed voltage you are getting out of it.

What do I need to test a 2 wire speed sensor?
There really is not a large amount of tools needed for the test itself, and they are not specialized either. The tools needed for testing either a 2 or 3 wire speed sensor are essentially a multimeter with the clamp leads, and a drill. The 3 wire speed sensor is externally powered, so you will need a power source of some form.

What are the symptoms of a bad transmission speed sensor?
Symptoms of a Bad or Failing Transmission Speed Sensor. 1 1. Harsh or Improper Shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears 2 2. Cruise Control Does Not Work. 3 3. Check Engine Light Comes On.
