EPC light turns on while accelerating on an incline and going into limp mode. I was recommended to do an EPR cleaning my mechanic is suspecting clogged filter to the sensor. I’m thinking I should just change it. I found the oil pressure switch at my local dealer. But they only have the brown one in stock. Should I change both brown and blue sensor and do the EPR cleaning? Or just do the EPR cleaning and see if it helps? Recent valve cover gasket reseal was done, PCV was changed, new spark plugs, new coils and new O2 sensor are in all were genuine parts too.

What is the code number? It might not be the oil pressure sender here is information I found on that:

An EPR cleaning involves using a chemical cleaner that is designed to break down and remove this particulate matter. This cleaner is typically added to the engine oil and circulates through the engine, helping to dissolve and remove deposits from critical areas like the piston rings and oil passages.

The process usually involves the following steps:

Adding the EPR cleaner to the engine oil.
Running the engine for a specified period to allow the cleaner to circulate and break down the particulate residue.
Draining the old oil along with the dissolved particulates.
Replacing the oil filter.
Adding fresh engine oil.

So, I would change the oil and filter after adding the cleaner and allowing it to circulate. Also, I have adding instructions in the images below and the location of the oil pressure sensors so you can check it out.
