C220 CDI

I have had a few issues with my engine. First the EGR valve, then split Boost hose then the boost sensor. Finally had a fault come up for the MAF sensor, fitted new sensor, but the SAME fault came back - 2025 - Pressure sensor downstream of air cleaner. Atmospheric pressure between component and CDI Control module is Implausible. Now i am goin down the route of a wiring issue between the MAF sensor and ECU. Does enyone have the Pin numbers on the ECU plug for the MAF sensor and the voltage i should be expecting. Thanks in advance
