Using dual in-cylinder pressure transducers

05/05/23

We are delighted to feature a guest case study this month, put together by the team at Autonerdz:

"It's no secret how beneficial the use of a pressure transducer can be. Being able to convert the pressure of the physical world into a voltage signal we can analyze with our scope gives us the ability to quantify things that we wouldn't be able to otherwise.

In this example we're going to look at a 2011 Jeep Grand Cherokee with a 5.7L V8. The driver's complaint is that the engine runs rough and the check engine light is on and flashing. A P0302 cylinder 2 misfire diagnostic trouble code was retrieved from the ECM. The client has replaced the ignition coil and 2 spark plugs for cylinder 2. For reference this engine has the Multiple Displacement System that deactivates cylinders 1,4,6,7."
