Re: Check engine light
Code 32 is for the EGR. Going thru the flow chart, there is nothing there for checking the BARO. You list you already changed the EGR valve and solonoid. May be a wiring problem or electrical open.
The BARO is monitored thru the MAP sensor. At key on engine off (KOEO), the sensor uses that reading for Baro pressure. Once the engine is started and running, that is the info the computer uses thru that key cycle. Then the MAP takes over reading engine vacuum.
