Testing sensors with multimeter


Recommended Posts

I'm having issues with my 2014 yz450f and I'm trying to test some of the sensors on the my throttle body, especially the throttle position sensor. I do not have the Yamaha diagnostic tool, just a multimeter. It says in my service manual to removed the tps to check the resistance, but if I remove it I have no way to then really set it back up. So is there any way to test it while on the bike? I tried unplugging it and then it just says OL (open line) on the multimeter.

EDIT : I just set the meter on 20k as I watched a video on it and got a reading of 6.68 ohms and the manual states that the max resistance on the throttle position sensor is 6.3 ohms so it is out of spec.

i also tried checking the crank position sensor and the only way I could get a reading was on 200k and the reading it gave me was 20.0. And the manual says the range is 228-342 ohms so I guess is you convert the reading I got with decimal points it would be 200 ohms. So that is also out of spec apparently.
