O2 Sensor

O2 Sensor
My 2003 V6, 2.1 Petrol, Right Hand Drive, Xtype Jaguar, has given me so many problems over the years, I’ve nearly reached the end of my patience with it, however, while I await delivery from England for a rear wheel speed sensor, I am seeking advice regarding another sensor I require. This, (according to my electronic reader) is; “Heater Control Circuit, Low Bank 1, Sensor 2” My question is, how much is one of these, and how difficult is it to fit, and could you PLEASE tell me, where I might get one ?. Many thanks, Docko

Docko, while not being familiar with your engine (the 2.1L), I have done the sensors on a 2.5L/3.0L engine. The downstream one should be easier to get at, just have to get under the car to access it. I would highly recommend getting an O2 sensor removal tool like this:
The others kinda work, but i have found that the socket type expand way too much and will slip when you go to remove the sensor initially (works fine for installing the sensor). You are going to need some umpf to get the sensor loose. So, having a 1/2" breaker bar is going to be another piece of tooling that you will need. Between the tool I linked and the breaker bar, really that is about all the tools that you should need other than lifting the car into the air. Having some PB blaster or WD-40 to get the rust to dissolve will be helpful too.
The big thing that I will tell you is to try and put one hand on the O2 sensor to hold it still as your other hand is on the breaker bar, loosening the sensor. This will help focus the twisting force on the sensor, not on trying to rip the exhaust off of the car.
If you need any other pointers, just ask.

Remember, Amazon is just a middle man in the big scheme of things. This is where the general standard I use is if it comes with the plug already attached, then you should be good. Most of the horror stories related to O2 sensors is either from the person not realizing that there are 2 different types of sensors (and therefore installing the wrong one in a location) or they thought they could save a few bucks by getting one of the universal ones and wiring it up themselves. Stick with that, you should be good. You get one from say Denso or another company like that, you will almost be ensured a good product.
