Where's O2 Sensor?

  • Sponsors (?)


What year Mustang? What engine? Does it have a aftermarket exhaust system on it?

A previous owner may have removed the O2 sensors down below if they changed headers, crossover pipes and exhaust system.

Otherwise, they are easily visible.
 
Well first off you will have some type of O2 sensor. They would not have been removed totally.

Second do you see anything that is stuck in or screwed into you "y"pipe with an electrical connector into that? If so then that is your sensor.
