Hello,

I had engine light with the code p1135.

I checked the sensor by multimeter, between terminal 3 and 4 i got 10ohm
so the sensor is fine i think.

but when i checked the harness multi-plug(terminal 4 and EARTH) i got 0.0V
so there isn't heater supply voltage.(igntion on)

how can i fix this problem?

update: when i move the plug of the harness sometimes i get 12V(like i should) and somtimes 0V
how can i change the multiplug from the harness?

Ok, so you've answered the first question yourself. :) Answering the second one: get a new plug, cut the old one and install a new one (likely by installing pins onto the wires and pluging them into the back of the plug).
 
Thank you for reply.

I tried to find new plug, but the seller told me to find used plug from the yard, cut the old one and weld the "new" plug instead, i will try to find plug and hope it will solve it :)

Yes, that should do in theory. One thing is that you would need to solder it well, because it might pick up some interference from outside world / engine / etc. Other than that, I don't see why it wouldn't work.
