Ford Passenger Side Rear Oxygen Sensor for all 2001, 2002, 2003 and 2004 Mustangs.
If your 2001-2004 Ford Mustang's check engine light has recently come on and you are feeling a rough engine idle, or beginning to notice poor MPG, you may need to replace your oxygen sensor. These 1R3Z-9G444-AA factory style replacement oxygen sensors come directly from Ford, and are correct for the rear passenger side of your Mustang.
The job of an oxygen sensor is to measure the amount of oxygen in the exhaust and deliver this information to the ECU in your Mustang. The computer in your vehicle will then use this information to adjust air-fuel ratios to keep your engine running smoothly and performing properly. If an O2 sensor is not functioning properly then your Mustang may not pass your state’s emission standard. This 1R3Z-9G444-AA Ford Oxygen Sensor is especially convenient when replacing your restrictive, factory h-pipe with a more open x-pipe or h-pipe.
Today, Ford is a worldwide auto manufacturer with sales throughout the world, and some of the world's most popular vehicles. Ford also has one of the longest continuously produced models with the Mustang. Not only does Ford make dozens of different automobiles, but they also manufacture many of their own parts for these automobiles, making them somewhat self-sufficient in many respects.
