Hi!

Yesterday I installed a new Joker Machine A/C and the XiED's.

When I wanted to check for errors, to see if they are working properly, I saw the error P0154 (only one) which means (after some research) Open/Inactive Rear Oxygen Sensor.

I removed the XiED in between and still got the error.

Important fact. I saw that i'm missing the little-black-plastic-end-plug of the sensor. Looks like this at the moment (picture is not mine):



A called a friend and he told me he lost it while installing new pipes... I can still plug it in tho.

Any sollutions please? Do I need a new sensor?

PS: I guess I've been riding with that error the last few weeks.

 

Yes, definitely get a new sensor, or buy an old sensor used and cut off the connector, and solder it up really good.

I would just replace it, that connector should be watertight or you could have issues in the rain.
