What Symptoms Indicate A Failing BMW 850CI Camshaft Position Sensor?
Sometimes your BMW 850CI gives you little hints when the camshaft position sensor starts to fail. One day it idles rough. Later, it might hesitate or stumble when you try to speed up. Power drops off and the car just doesn’t feel as quick. You may crank the engine longer than usual—and sometimes it won’t fire up at all. The check engine light can show up, usually with codes about camshaft or timing issues. It’s tricky, though, because these problems don’t always stick around. They come and go, leaving you to wonder what’s wrong. If you wait too long, fuel mileage starts to slip and performance keeps getting worse. Early action saves a lot of headaches down the road.
How Do You Test If The BMW 850CI Camshaft Position Sensor Is Bad?
If there’s trouble, testing isn’t hard. You can start with a scan tool and check for trouble codes—especially ones tied to the camshaft or sensor. A lot of people also use a multimeter to check for the right voltage or resistance at the sensor connector, holding the reading up to what’s listed in the manual. If you have live data through a scanner, you can actually see if the sensor gives jumpy, missing, or strange readings while the engine runs. If things look off, or if the wiring and connectors are fine, replacing the sensor is often the next move. It’s better than chasing your tail over the same problem.
Where Is The BMW 850CI Camshaft Position Sensor Located?
The sensor sits near the front of the engine, right by the camshaft gear or behind the timing cover. BMW tucked it close to where the camshaft spins, so it can read the cam’s position right away. Sometimes you need to pull off some engine covers or intake tubes to reach it. The spot is a bit cramped, especially with big V12 engines. A repair manual or a clear diagram helps a lot, so you don’t unplug the wrong thing or get frustrated. Knowing where it hides gives you a shot at swapping it yourself or explaining things to your mechanic without any mix-ups.
How Much Does It Cost To Replace A BMW 850CI Camshaft Position Sensor?
Cost is always on people’s minds. The sensor itself falls between about $50 and $150, depending on who makes it and where you buy it. If you tackle the job in your garage, you’ll mostly pay for the part and maybe a gasket or two. If you go to a shop, expect the bill to go up, since labor rates can jump based on where you live or the shop’s size. Dealerships ask even more, as you’d expect. Add it all up, and many people weigh the DIY route for this fix unless the job feels too tight for a Saturday afternoon.
Is It Safe To Drive With A Faulty BMW 850CI Camshaft Position Sensor?
Driving with a failing camshaft sensor isn’t really safe. The car can stall out or refuse to start out of nowhere. When the sensor blips, you lose power and might be stuck on the side of the road. If you push it, you risk messing up timing and fuel delivery, which can turn a small fix into a big payout. Most folks—mechanics included—will tell you it’s best to get it fixed at the first sign of trouble. The risk just isn’t worth it, and waiting usually costs more in the end.
