transmission light will come here as well guys and it will tell us that we have a problem so definitely guys definitely something's wrong with that thing okay it still says transmission malfunction there four by four because it's an all-wheel drive oh right there transmission light is on so uh let's go ahead okay take care of that problem and show you what we need to do to fix it now so if you guys have a bmw 3 series that starts super slow like we showed you guys and uh you have transmission light start slow it's not acting good okay we scan the system we got code 2e94 this code is related to crankshaft position sensor guys uh nine out of ten times when you get start slowing bmw and transmission light at the same time it's guys okay uh it's actually the crankshaft position sensor but before we start guys now first i want to show you where it's located and it could be not the sensor itself and that's why we are making the video but if you want to see how to get to it and how to do that we have the complete video from start to finish on the channel how to remove and replace crankshaft position sensor it explains everything guys you need to remove the intake manifold we have that video as well everything from start to finish but a few common mistakes people make when working on a crankshaft position sensor they do not disconnect the car battery guys okay mistake number one super important and you're very close to the uh this is your engine starter positive wire coming from the battery going to the alternator as well you're going to be disconnecting your fuel line so if you guys make sparks from touching this wire to a sensor or a ground wire somewhere you make spark you can catch your car on fire yourself it's extremely dangerous guys you can short things out you can burn engine computers modules and cause damage to the electrical system mistake number two people don't know that but on modern vehicles it really depends uh it really makes a difference which battery terminal you disconnect and reconnect first so you don't cause more damage to the electrical system guys if you don't know that we have a special video that explains that which battery terminal to disconnect and reconnect and i'll try to put the link in the description of the video below with all that being said if your car doesn't start guys fast and you have transmission line you come right under the starter and there is one wire this wire is for your crankshaft position sensor often guys this wire may be a loose wire okay it may not look loose but it's loose guys or broken wire okay will mimic the symptoms of a bad sensor that's not working correctly and that will happen now the sensor itself is right there but usually you may have a lot of dust dirt and sand there so you need to clean and vacuum it before you remove the sensor we will show you now with reverse torques 12 we're going to remove the sensor if it's not a bad wire loose wire or broken connection somewhere you need to replace your sensor guys but if you you have to verify that you have that code and the engine light is on and you have a code related to a crankshaft position sensor on your bmw and uh the code guys will say that the crankshaft sensor signal is missing or something like that so grab the sensor it may be stuck jiggle it a little bit if it hasn't been removed in a while it may be really really stuck this is the o-ring that gets stuck and this is guys the sensor itself that's what can cause that problem uh nine out of ten times that we get that at the shop new sensor or just reconnecting the wire fixes our problem with no problem guys so hopefully the video will be helpful thank you for watching please subscribe and see you guys next time
