Video tutorial

In this video, you can see where the lambda sensors are located on a Mazda CX-7 and how to proceed if you need to replace them. These sensors are very important for the proper functioning of the engine.

As shown, the first sensor is located on the exhaust manifold at the rear of the engine, while the second is positioned after the joint of the manifold to the single pipe. To remove both sensors, simply unscrew them using the appropriate socket, or alternatively, you can use a spanner of equivalent size.

If they are difficult to unscrew, apply some penetrating spray to the threads.
