We are trying to locate where the oxygen sensors are located on the Ford Ranger. We think they are bad and want to replace ourselves to save some money.

Thank you,
Lynn

Hello,
The oxygen sensors are located on the exhaust pipe right after the exhaust manifold (see diagram below).
These can be changed very easily using a oxygen sensor socket. It is a good idea to use penetrating oil before removal of the sensors as they are likely seized on the exhaust.

Here is a helpful article:

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
