testing a crank sensor (non ford)

[Danny1107]

my sisters boyfriends clio is running really bad, missfiring alot and i know a common problem on them is the crank sensor, is there a way of testing a crank sesnor without fitting a new one to see if the problem is still there or not?

 

its missfiring alot then occasionly runs ok but feels like its holding back on power, I've told him to take it to renault on his day off to get them to check it with the diagnostics, when I used the college diagnostics gear it wouldnt connect with the ecu

 

any ideas how to test the crank sensor? or any ideas on what other things to check?

you can take it out and clean it ,the only other way is to do a ohms test on it if you can find out the specifications on it ,using a multimeter

the best way to test is with an occliscope (sp)

As far as I know an oscilloscope is the only way to test the crank sensor because the signal from it is too fast for anything else to be meaningful.

You could make some kind of moving coil meter with an amp for an inductive pickup.. then you can move the wheel as slow as you like and observe its function.. probably a bit out of scope of this request though

thanks for the replys, going to see if i can hook it up to the occiliscope at college to check it
