I need help on how to remove the 02 sensor (bank1, sensor1) in my 2.7 V6 09 Charger. Once I get my socket on there's not enough room to turn the breaker bar. Not sure what to do...?
1. Soak in PB or other penetrant
2. Cut the wiring harness at the top of the sensor
3. Fit a proper deep well socket (I like the special O2 sensor sockets, but with the slit they can be a bit less stable/strong)
4. Add enough extensions to give adequate "swing room" for your breaker bar - keep the extensions as straight as possible - in line with the sensor
In my experience, once she breaks loose you should be able to spin it out by hand.
