    I used a 25k pot instead of 2 resistors...trigger wire hooked to the center terminal of the pot. Worked the same and found I had an intermittent problem. Seems like either some gooey stuff had leaked out of the thing indicating a problem. Buying a new or used sensor next but Im sure this is why my volvo wont start anymore. Seemed like it was running good then would run rough then get better....then run worse....then run ok.....then low power....then ok......finally wouldnt start any more. Code reader said P001...camshaft position over advanced..So i figured Id pull the sensor out and your test shows intermittent problem....sometimes it works...sometimes it dont....and in cold weather it wouldnt even start. Thanks for this video !!!!

  • @kevinfoster2308
    @kevinfoster2308 3 года назад

    I have a sensor off of a Suzuki ATV and the manufacturer maintenance manual says the hall effect speed sensor can fluctuate from 0-6v or 6-0v when a suitable ferrous metal object is placed in front of the sensor if it's working correctly. So when "unactivated" it read 6v or 0v.

    Now which one you said is the ground because my ohmmeter didn't tell me.
    I don't know how yours did. I like to buy your meter. Can you tell me it's make and model. I like that kind of ohmmeter.

  • @haorangeng4230
    @haorangeng4230 2 года назад

    great video, i got a question, why you give 5.5v and 12v at the same time to the sensor? if we give only 12 to the sensor, and detect the voltage between signal and GND, can we get the correct signal voltage like 4.8+ and 0.8-? other words: in your model, the multimeter reads the voltage of sensor and your lower resistor in paralelle, is that right?

  • @SerenoOunce

    Test may show if a sensor is dead, but still need an oscilloscope to determine if signal is clean or noisy garbage. Air gap tolerance is far too sensitive to replicate on a bench.

    • @hodumx
      @hodumx 11 месяцев назад

      From someone on the other side of your experience, best answer would be one that doesn't answer your question. In your scenario, you're going to have to continue checking upstream from your sensor. That's right, start checking your wiring visually and for continuance ( continuity check the wire and test it against any possible ground around it.) And then test where it ends. On and on and on. Eventually, you will hit a fault. Don't worry you'll learn like I did.

So than I can test the other lead in the sensor ?
    Or do I need additional components and I’m missing something
    Or is wiring jump wires connecting post and neg to each other from massically looping the batter the way wrong thing to do and I’m miss reading this and it will end in failure ?

      Because that 5V signal is what ECU reads. 12V is just to power the sensor. You could just use 12V and 5V power supplies, instead of voltage divider.

      I asked around and got advice not to. It's not always as simple cause the ECU might control the voltage as well and bypassing that with constant voltage might do something unexpected or maybe mess the ECU. Or maybe nobody's dared try it yet :D. Well, I guess I'll check my wiring first.

  • @draganciprian3221
    @draganciprian3221 4 года назад

    Hi all! To my knowledge most engines use two types of Crankshaft sensors. 1. Inductive (magnetic) which are with one or two pins on the socket and which are capable of producing an electrical impulse without being supplied. 2. Those of hall-effect type that have 3 or 4 pins on the socket and that generate a digital pulse (square wave) provided they are supplied with a specific electrical current. Regardless of the type of Crankshaft sensor when measuring directly on the sensor with the multimeter, any type of good (not flawed) Crankshaft sensor must have a resistance of X ohms? I ask for your help in this problem because I am facing the following situation. My Crankshaft sensor no longer functional. I removed it from the engine and measured it with the digital multimeter directly on the pins. No resistance. I thought it was burnt (defective) and I bought an identical original one. When I received the sensor, before mounting it I tried to check it. Same thing. It has no resistance whatever the configuration of the measured pins. 1 with 2, 1 with 3, 3 with 1, etc. Nothing, no resistance in ohms, kohmi, although this sensor is new..
    My question is: Regardless of the type of sensor crankshaft as long as it is operational (good) when directly measuring it with the multimeter must it have a certain value? My sensor type is a Mitsubishi ME203180 and as I reported above. Neither the new nor the old multimeter measurements indicate anything. Obviously the scale of the multimeter is selected correctly. Is it possible to be a perfectly operational sensor and not indicate any resistance when measuring with the multimeter?
    Thank you in advance!

    • @therandommech9099
      @therandommech9099  7 лет назад

      This is probably a bit late, first answer, I believe that the pins on the sensor are polarity sensitive, so switching the test leads around may or may not solve that issue. Second answer, it could be that the crank sensors on e46 could be a pull up type sensor instead of a pull down type since the voltage went up to the battery voltage (note i am not very familiar with the e46 set up). You can also test the wire harness connector to see what type of sensor the engine uses. I believe that on the e46 the yellow wire is the signal and the black wire is power and the third wire is ground. First, you can use a multimeter to measure the signal wire(yellow wire) when the car is on the "ON" position or when the engine is cranking depending on the DME, if there is a reference voltage 5 volts or above, it is most likely to be a pull down design, on the other hand if the voltage reads 0 it could be that it uses a pull up design. Well, hopefully this helps.

    • @travis5125
      @travis5125 7 лет назад

      Yes. The hall sensor is a semiconductor, so the polarity certainly matters.
      Make sure to check both directions. Also, the resistance might be too high to be measured by a resistometer with a weak battery. It can take a bit of voltage to get current flowing through a doped semiconductor.
      These are designed with high resistance to keep the current low. Paradoxically, the hall effect is most powerful at low currents. (Try the hall effect with copper if you don't believe me.)

  • @jsincoherency
    @jsincoherency 7 лет назад +1

    Hello, I have a 3-wire speed sensor and I can't tell which wire is which. I've connected a multimeter across it in every possible way (with both polarities) and have infinite resistance between every pair of wires, but I know the sensor works because I took it out of a moped with a working speedometer. I tried wiring it up with the voltage divider and multimeter to measure voltage change when I bring a large metal object near it like in your video, and couldn't get it to react to anything. Any ideas what I might have done wrong?

    • @therandommech9099
      @therandommech9099  7 лет назад +1

      It does look like your sensor is a hall effect type sensor, but I could be wrong, even so, depending on the sensor, the resistance between the signal pin and or the voltage reference pin to the ground pin should be around the 5 to 7 Mega ohms due to its circuit design and the best way I can see to get a pin out is with a use of a service manual (that's if you can access one) or a wire diagram to trace each wire to each individual pins.

    • @therandommech9099
      @therandommech9099  7 лет назад +1

      I believe that the internal operational amplifier is the reason why there is such a high resistance and if you know anything about op amps, an op amp has a high input resistance/ impedance to prevent loading effects on the input circuit. Hope this helps to explain this reason.
