Question: check engine lite on

I have been told by my local mechanic to change all 3 O2 sensors: #1@50%, #2@40% and #3@55%, all for $2,868.00.
Is this correct price?

That seems way too high.

And it isn't too likely all the sensors failed at the same time unless it is a problem that has been going on for a while that hasn't been looked at. A quick parts check shows the front O2 sensors are about $200 each and the rears are about $70 each. So three sensors sounds like it should be around $1000 or less. But I don't have the specifics of your issue or engine size so that is just a guess. That price sounds more like the price to change factory catalytic converters. And even at that, it sounds a bit on the pricey side.

I'd get a second opinion. You can also check our repair cost calculator for a general estimate of how much each sensor cost to replace.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
