Home and Auto Oxygen Sensors - Page 3

Okay. I looked up oxygen sensors, and I have a basic idea of how they work. My check engine came on a week or two ago, so I finally got it taken in to the shop to have a diagnostic run. They called me this morning, and told me that I needed a new sensor. I wanted to do my homework to see if this might cause things that I've noticed about the car. I have noticed that my fuel mileage hasn't been as good. This can be caused by having a lean mixture of oxygen, so that makes sense. I'm wondering, and I will continue to research but thought I would ask you car gurus, if something like that could make your car run a little differently. I'm not going to say how, as I just want to find out what could happen and see if it compares to how I feel my car has been running.

Also, the part and labor is going to cost me $390. I wanted to see if that was fair or not. It's a 2002 Lexus IS300.

Luv, if you have the paperwork, list which code it is setting and I can tell you which O2 it is. Either way it is worth resetting with an OBDII to find out if it comes back on or not.

It's getting fixed in the morning. I will be going over the invoice with a fine tooth comb before paying. I've been doing my homework today.
