Xtrail oxygen sensor plug issue

Recommended Posts

Hey guys, recently bought a x-trail and thought I should change the oxygen sensor due to the bad fuel economy. I've taken off the heat shield for the extractors, and managed to unscrew the oxygen sensor but for some stupid reason the plug is extremely difficult to take off. Is there any tricks to taking off the oxygen sensor plug? I dont want to spend $50 to change an oxygen sensor when my only issue to pulling the plug out.

 

Ive had multiple friends and family attempt to take out the plug and fail. Any help or advice will do, much appreciated!

Push the male and female connectors together, depress release tab, then pull apart.

 

To be honest, I don't think an O2 sensor is going to fix the shitty fuel economy Xtrails have.
