Hasan Ahdemir, thanks for sharing your experience. How did you attach this to a drill to spin it?

@@MotionDesignStudio You can see from this video kzfaq.info/get/bejne/ps1niNGgzJ2ldps.html

@@hasanakdemir5911 , thanks for the excellent video. I will try a drill next time. It will reveal intermittent failure very easily.

The speed sensor is not a common place of failure. You most likely have failure within the instrument cluster. In the video I show you where. That is most likely it. That big chip fails and sometimes you might find moisture ingress that rust things. You can easily verify your speed sensor is working by using one of those Bluetooth OBD2 readers and look at the live data of your current speed, best of luck and happy New Years.

anthony picado, really happy this information will be of use to you. I really thought about it much because I was in the process of diagnosing my vehicle speed sensor and needed to rule out that the speed sensor I was going to install was not the point of failure. In the description is link to another video with a complete diagnosis of the vehicles speed sensor and speedometer. I learned something of interest after creating this video. "SPEEDOMETER: Indicates 60 km/h at 637 rpm or 60 mph at 1,025 rpm of the vehicle speed sensor (VSS)." I got that from the service manual for the 1996 - 2000 Honda Civic.

It is so nice that Honda/Acura kept things so similar over many models and generations of their vehicles. Best of luck and keep us updated on the outcome. Have a great week.

Thanks

What my multimeter is set to is the most asked question. I really need to do a follow up video to help clarify things. One sec will respond later.

I hope this information helps you diagnose the issue. Best of luck and have a great week.

Thanks and have a great weekend.

Please explain more. I do not understand.

I am not sure what you are asking?

You have two choices. You can send me a link containing a wire diagram for your vehicle's speed sensor and I can speculate how to create an equivalent test. Number two is send me the sensor and I make a KZfaq video on how to construct the equivalent test. Upon completion I will return.

@@MotionDesignStudio ireally dont have a diagram for the vehicle im installing a Toyota cressida engine in a Toyota bus so I'm using the cressida speed sensor so i wanted to know how to check the cressida speed sensor how to connect the positive and the negative and the signal wire i know many 3 speed sensor wiring sometimes wiring different..please and thanks🙏

@@christleydacosta4747 Google the words from this and you can find the link. To test this you will need to check the output of pin 3. :: From a website ::: 3 Wire Speed Sensor The 3 wire speed sensor output signal is a square wave signal that connects between the input power source (battery voltage) and the power ground. The speed sensor outputs 4 pulses (High to Low voltage transitions) for each speed sensor revolution. Most Toyota 3 wire speed sensors have the below (90980-11143) plug connection, however it is worth noting that there are some 20 pulse / revolution Toyota speed sensors that have a different (triangular) plug connection. Note, the below plug (90980-11143) connects to the speed sensor, the below plug image does not show the pin out of the sensor, it shows the pin out of the plug that connects to the speed sensor. Pin 1 : This pin is used to supply ignition switched battery power (+12V) to the speed sensor. This pin needs to be connected to an ignition switched power source that supplies battery voltage when the ignition is in the RUN and CRANK Positions. Yellow (Y) Pin 2 : This pin is used to supply the power ground for the speed sensor. This pin needs to be connected to ground. Red (R) Pin 3 : This pin is used to output the speed signal. This pin most commonly connects to the dash cluster, however in some arrangements this can vary. The 3 wire speed sensor output signal is a square wave signal that connects between the input power source (battery voltage) and the power ground. The speed sensor normally outputs 4 pulses (High to Low voltage transitions) for each speed sensor revolution. Light Blue - Red Dash (L-R)

Pull off the socket at sensor. Switch ignition on. Meter negative to centre connector, and positive to one outer, then the other. One will give full battery 12volts. Turn the ignition off. Remove the protecting sleeve from the 3 wire harness, and push a needle through the wire that is NOT 12volts. Jack up front wheels, connect meter between the needle and earth. Gearbox to neutral and ignition back on. Spin the wheel and it should go 12v-0-12v-0 for each revolution.

Looks like the code you mention map to this "P0720 Honda Code - Output Shaft Speed Sensor Circuit Malfunction". You are ultimately responsible for making an assessment on the safety mechanically and to others while driving your vehicle. With that being said a non functional speed sensor you can drive with as long as the automobile does not need to know that information to regulate fuel flow.

I do not understand your question.

@@MotionDesignStudio i cut the snap on connector for the speed sensor from another harness. I snapped it to the sensor i am going to test. I an do the same test with thethree leads copming from the connector which i cut from the harness correct. I tested my speed sensor from my car which i bought from an wrecking yard(assuming it is good?) I did not get the fluctuation of resistance ui did. Any advice??

@@andredial6436 , that is the best way to do it with a connector with wires. Start with checking the continuity on the connector to the pins on the connector. If that is good then double check the setup and make sure everything is connected like mine especially the battery.

@@MotionDesignStudio i did it the way u showed on video. I turned the spiral gear but no movement on my meter, it just stayed about 30ohms, with the setting at 1ks ohm,. So? Thnx

What if i put it back on the car and check resistance while car running at different speed, will i get fluctuations on my ohm reading??

It is set to measure voltage DC! Hope this helps and thanks for watching.

As much as I would like to answer this. There is no way I can answer this without you sending me a wiring diagram of your vehicle that includes the speed sensor.

@@MotionDesignStudio I don't know n have wiring diagram of the vehicle, but I can send you pics of sensor, it's same as urs but it has two pin socket.

@@khajuriaarun8874 , get a wiring diagram from alldata dot com.

I would say you might have a bad sensor.

This came from a manual transmission 1997 Honda Civic with the engine block code D16Y7. I am unsure of the classification string you provided and how it aligns with this vehicle. I want to emphasis the manual transmission and the automatic transmission have a completely different vehicle speed sensor.

You need power to test this. If you just spin it outputs nothing.

Everything is volts D/C.

He answered the same question on previous comments.

@@balloney2175 Needs to be in the video.

@@RobertBarrington Ok. His mistake.

Bal Loney, thanks for pointing this out.

As a question for clarification. That is great way to start.
