How often do you clean your MAP sensor?

Many of our company trucks never threw codes when the sensor was clogged, but definitely showed signs of reduce power and increased fuel consumption.

From what I was told, a clogged map sensor is slow to respond to pressure changes or gives a false pressure reading than actual therefore telling the engine to give the wrong amount of fuel. It can do this for a long time before actually throwing a code since it is still telling the engine a pressure that is within its parameters, just the wrong pressure.

I used to clean mine every oil change at 15k, but now I do it every other oil change since the EGR is not spewing soot all over it. I have seen a dirty MAP sensor have a significant impact on performance and fuel economy in some of our company vehicles so we have made it a regular maintenance item.

Just wondering how often others with diesels clean theirs.

Unless it throws a code; never. If it throws a code it's outside of it's parameters and I will take a look at it then.
