Description Reviews MINI OEM Map Sensors for all Gen 1 cars. Sensor 648 fits the R50 MINI Cooper 2002-2006, as well as the R53 MINI Cooper S 2002-2006, the R52 MINI Cooper 2004-2008, and the R52 MINI Cooper S 2004-2008. This sensor reads how much air pressure is being brought into the car post throttle body. It is located in the intake manifold in the MINI Cooper and is located next to the valve cover on the MINI Cooper S (see photos). Read the codes so you can replace the correct part, the first time. Without reading the codes and doing the correct diagnosis, you're just throwing parts at the car, and that can get costly. Here at the shop, we see sensors go from time to time; but there is no rule of thumb to say sensor X always fails, and you don’t have to replace both when doing this repair. However, if you are doing a motor build, it is recommended. 2 Reviews 4 sensor Posted by Bradon on 22nd Apr 2020 A little pricy but its oem and fixed my problem perfectly 5 Product Got Rid of My Error Code Posted by Marshall on 6th Sep 2016 The car was displaying an error code of p1237. After replacing the sensor the error code has not come back. The part is great, and only took a few minutes to install.
