We need to locate this sensor

We got this sensor missing from the top of the engine (left-side, right above the valve cover, picture attached).

There are two sensors of this kind - one in the front (which is missing from our engine) and another in the back. Engine runs fine but the Check Engine is on. Unfortunately we don't have a scanner for this type of engine here in Europe.

Does anyone know what kind of sensor is this so we can order it from a parts store?

Anyone with the 2.7 DOHC engine?

It looks the the capacitor for the ignition coils. The 2.7s have one on each side. All it does it store excess voltage from the coils.

Thank you! I just ordered it online :)
