'00 Explorer questions

Iwaslooking at a'00 Explorer down the road for sale . The info on the windshield said it had 91k , but needed an O2 sensor, and two door handles. The door handle thing I have heard of and can fix no problem, but how big a deal dollarand time wise is the O2 sensor , and what other problems should i be aware of? They want $2000.

If it is the OHC engine check if the PO has had any timing chain issues. Check the service records on the transmission.

Run a diagnostic and pull all codes, why does he think it needs an O2??

In addition to the SOHC timing chain issues, make sure all the climate control stuff works properly. You don't want to get into a blend door fix issue.

A 2000 Explorer will either have 3 or 4 heated oxygen sensors (HO2S) - one for each cylinder bank and one after the catalytic converter. If there is a converter for each cylinder bank there will be a total of 4 O2 sensors. If there is only one converter there will be 3 O2 sensors. I think by 2000 all Explorers had 4 HO2S, but I never inspected a V6. I've never heard of a vehicle having 6 O2 sensors, what the heck model and engine of Ford was that!?!
