The 2005 Ford Mustang is equipped with four oxygen sensors that are connected to the exhaust system, catering to both engine options: the 4.0L V6 and the 4.6L V8. Due to the Mustang's dual exhaust system, it requires two sensors for each exhaust, totaling four sensors. These sensors are located before the catalytic converter near the exhaust manifold and after the catalytic converter on the exhaust pipe. The replacement cost for each sensor is estimated to be around $40 - $50. If you are conducting the repair yourself, ensure that you identify which sensors need replacement because the rear sensors differ from the front sensors and are not interchangeable.
