O2 Sensors
I've done pretty much a total full tune up to my brothers 2004 with the 4.2L Heritage V6, he is asking me to do the O2 sensors, I am having trouble finding out if there are 2 or 4 sensors.
Anybody have any idea? |
Dual cats have 4 sensors, 2 upstream, 2 downstream.
Of course you could crawl underneath and count them. |
Aye, there was not enough beer in the house to allow me to crawl under there Mike, lol
I thought about it, but I had just got done changing out the plugs and wires. Since there are 4 he may say screw it, but if he gets them I'll gladly put them in for him. Thanks for the response Mike, hope all has been well! |
Any suggestion for replacement sensors?
I see Bosch listed as OE.. If my bro gets them he is considering BOSCH15717 But if there is a decent cheaper part he would go that route as this is not really a daily driver, it is just a backup truck which he is letting me drive while I work on my Grand Prix.. I found this pic, posting in case it will help others in the future. https://cimg6.ibsrv.net/gimg/www.f15...da2892cb1b.gif |
