When I got the exhaust/tailpipe replaced the guy said the O2 sensor was most certainly shot too. How do I replace it? It's been on there for 16 years. Will it help much for gas mileage or performance?How much to replace an oxygen sensor on a Toyota pickup?The sensor is about maybe 40.00 and the labor another 25.00, if he's nice. So about 65.00. That's if the sensor is an off brand. if it's an original Toyota part then it could be about 150.00 for the part.How much to replace an oxygen sensor on a Toyota pickup?Depends on the labor, figure $200.
Your remove the old one and put in the new one. Thing is, the old one may have to be cut out of the exhaust system.
Yes it will help with your gas mileage and performance. It will also make the %26quot;Check Engine%26quot; light go out, unless you have other problems.
