Where I live, vehicles have emission requirements to pass an annual
State Safety inspections. My Van recently had this inspection and the
shop said my van failed because the Check Engine Light on the dash was
ON. They did diagnostics and said that at least one 02 sensor was bad.
At the time, I really did not want to spend the money! (That was
about a month ago.....). I paid the shop $800 in other work during
the same visit, and I paid a LOT for the diagnostic...
The shop did not know which sensor failed, but suggested replacing all
I'd like to install the new sensors myself. I've seen one and it looks
pretty easy. I do a lot of routine maint. on my motorcycles and cars.
I've seen new sensors online selling for about $20 - $35 each each.
What I could use a little help with is:
1. A diagram showing the location of all the sensors. I understand
ther are 4: is that correct?
2. The acutal specs and /or part nos of the sensor I need.
3. Any advice on doing this job.
Once I get the van to pass the inspection, I want to sell it. This
Ford has been a very expesive vehicle with a LOT of prob's since I
bought it in 98!! It has 128,000 miles now.
Thanks very much!!
