Question about Ford Windstar
The Windstar has four sensors in the exhaust system. Each side (bank) has two sensors. The first sensor after the exhaust manifold is the oxygen sensor and monitors how that bank is running, sending information to the computer. The second sensor is a catalytic converter monitor sensor. It monitors the job the cat is doing, sending info to the processor as well. The connectors are blue or gray (factory) and are located on the engine side of the exhaust. The front sensors are a little more difficult to get to then the rears.
There is also a sensor called a DPFE that measures back pressure from the exhaust and is used to properly operate the EGR system. It is located on the left side of the engine torward the rear of engine (front of car). Good luck.
