I've been trying for days to find location of the crank shaft sensor in distributor in a 1992 civic, I guess this is the best video to see the models with that type of mechanic" Back in 1982, My friend and I were going 125 miles per hour challenging that Sport Datsun like yours on the freeway from Georgetown to Austin Texas, Suddenly a guy started to leave us behind and waited for us 100 meters ahead , when we cought up , again he left us , but that little car can run, We were having fun, but we got cought and arrested and spent 2 days in George town jail," But still 125 miles speed is fast , Now Im 60 and my son say that I drive like a turtle.🐢 Thanks to God I never had a horrible accident. That is a beauty full automobile you have there.

I have the same plans to use that turbo dizzy to trigger my cam sync to the MegaSquirt 3!!! I'll be able to run both COP and sequential injectors, assuming i dont muck it up....LOL! Nice demonstration with the meter, will help my troubleshooting later, thank you.

I'm going to run a 36-1 crank trigger, VR sensor for the tach and the turbo dizzy with the DIY slotted wheel for the cam sync, optical sensor. Gotta lotta soldering to do, LOL. I'm going to use FI manifold from a 280Z and an aftermarket throttle body. Might be okay.... if I can pull it off. thanks again for your videos, i'm doing alot of the same things you are.

Thanks for the info! this looks like it applies to the 300ZX (Z32) 1990-1996 as they use a combined CAS that runs off one of the exhaust cams.

zeb stanbrough from what I can tell from my own experiences, I think it’s relevant for any Nissan optical CAS eg. SR20, VG, RB engines. I think Nissan took the idea and blanket applied it to everything! Good ol’ Nissan! 😎

Great video, I have a 2000 Infiniti g20, aka Nissan Primera, dame trigger wheel in the dizzy. Visually I can see some chips in on the outer rim of the wheel, I’ve been trying to hunt down a bucking issue that only seems to happen around 1700. This video has given me some confidence to tackle the job.

So if I attach my multi meter to the white wire and get nearly no response but then attach it to the green wire and get 1.4 volts and slightly above, would that indicate the crank angle sensor is working properly or that it is not working properly? Good reading on one of the two wires?
@kyushaspeed

Hi Eddie, I would consider reading on only one of the signal wires to be a bad CAS. Does the voltage change when you rotate or trip the optical sensor? The change in voltage is the important thing.

Hi mate, I love this video! My VLT has died and it has no spark. I have an Autronic ECU which runs a different chopper disc in the distributor. It has just 6 large slots, so I guess will give a different voltage reading to a standard Nissan disc. I just performed the test you did with the dizzy still in the car. At cranking speed I managed a maximum of .405 volts. I gather this is far too low and the CAS is dead?
@kyushaspeed
3 жыл бұрын
A benefit of the optical CAS design is the output voltage is the same regardless of slot size, it is simply a switch triggered by light. As far as determining if the CAS is your problem, have you investigated other aspects of your ignition (eg. ignition coil, does the tach register an RPM during cranking)? From memory the ECU on a VLT should report codes using two LEDs. This might give insight into problems.

Hi friend thanks for the video, how much power are you plug in the sensor to test? Are you doing that with 12 volts or with 1,5 v because i have my l series disambled and need to test the sensor so I was thinking on plug some power in order to test the sensor.

I used 12V for power supply. The CAS sensor was developed before 5V active sensor supply became the norm.

@@kyushaspeed thanks for answer me! is 12 v for supply and then 1,5 volts to test the pulses right? and you put the negative of the voltimeter on the ground and with the positive you test the two resting wires.

Removal depends on the unit. I know removal for an L28ET and RB30E distributors. If it is from another motor, the process is likely a little bit different.

I'm not aware of one specific reason why the sensors might fail. Failure seems to be largely dependent on the quality of manufacture.
