Friend of mine hooked his computer up. Looks like one of the front sensors is bad. Question is 1) should I change all of three of the sensors. I have 168,000 miles

2) Where is the cheapest place to get them. So far Courtesy has quoted me the lowest at $70 for each of the front and $117 for the rear

thanks anyone else have the same problem?

 

man, they quoted me $83 for the fronts!!!

What kind of computer does he have? What did he hook it to?

 

Let's see first off the qoute from courtesy was off the internet. They give a better price on the internet instead of over the phone.

My friends computer was a snap on product. it's red. He hooked it up to a plug next to the fuse box under the steering wheel. He's a Lexus service technician. Not totally familiar with maxima/nissan.

Again anyone have any thoughts on whether I should change all three at this point. I've got 168,000 miles.

 

I suggest you replace both front sensors. The Engine Control Module uses signals from the front sensors to control the fuel mixture. When both front sensors are operating properly the rear sensor is used only to monitor the performance of the Catalytic Converter.
