OK, i haven't had any trouble with my truck for a while. But i will preface with i had a short in the system a while back but i thought i fixed it. Yesterday on my way to work it tripped into limp mode. Today i got the codes read and it is p0237 and it read turbo charger boost sensor A circuit low. Because i lost my repair log i can't remember if that was the code it was throwing the first round. When i search the form it seems to be a map sensor. And one guy said that he had success just cleaning the sensor. So my question is where is the map sensor and how do i clean it. please help I got to get her running for work on Monday.
