Hi

ive wired everything up outside of the car to make sure all my connections are ok. checked continuity on everything but i dont get any between the 2 vr sensor connections, is this right or have i got a bad connection somewhere??

thx

alex

A quick check on a VR sensor shows that it has a resistance of almost exactly 250 ohms - so if you are using a simple 'continuity tester' on the VR sensor terminals it's likely to show it as an open circuit....

....assuming that's where you are measuring - if not, please explain further

From the question, I read it as your testing across the two contacts in the socket that connects onto the vr sensor, correct? In which case open circuit is correct.

...and if you are testing across the two contacts in the socket that connects onto the vr sensor (ie you're attaching your continuity meter directly to the VR sensor inputs on the EDIS module), then that's not particularly recommended, or useful, thing to do

You can check the VR sensor by putting the meter into AC mode and waving something steel past the end. You should register a small current from it.
