awayner1 0 Report post Posted January 30, 2023 Just in the process of installing a M52B28 engine into a E36 and having a problem locating a sensor to match the loom. My loom has a 6 pin plug and all the sensors I can find are 4 pin. Does anyone know which sensor has a 6 pin plug? Quote Share this post Link to post Share on other sites
NZ00Z3 186 Report post Posted January 30, 2023 The late model E46 (M54 with MS43 DME) has a 6 pin MAF connector. It includes the MAF and Inlet air temp sensor. Check the wires colour coding and work back to the DME to see what the extra wires are for. Here is the DME pinout: http://www.fekzen.se/StandAlone/ Quote Share this post Link to post Share on other sites

Might be mistaken but from what I've gathered, only the US models ever got those. Here's the 6-pin MAF. I ordered one by mistake but luckily caught it before the order was shipped, mine was the old 4-pin style. Mine's an M54B30 though so might be different for the M52. Is this what the connector looks like? Surprised to hear the M52 having those tbh. Quote Share this post Link to post Share on other sites
