How to replace the front o2 sensor in a Volvo 850, S70, V70, etc., error code P0133 – REMIX

How to replace the front o2 sensor in a Volvo 850, S70, V70, etc., error code P0133 – REMIX

O2 sensor replacement: 1 to 2 hours.

I replaced the o2 sensor in my car because my gas mileage was running low and everything else in the ignition system was up to par. The front o2 sensors should probably be replaced every 100,000 miles or when you get the error code P0133. I did not have the code but did have poor gas mileage. Since the replacement my mileage has improved around 15%.

How many o2 sensors does a 1998 Volvo 2.5 turbo have? If more than one, which one should I replace? I have no check engine light on but my gas mileage is worthless.

Hank Fleming says:

Thank you sir. This looks to be an easy job but still happy to find your video just to be sure I am not missing something.
Glad to see the bit on the connection as that may have fought with me.
With your videos I will have cleared all my codes.
