What Are The Symptoms Of A Failing BMW 733I Camshaft Position Sensor?

When the BMW 733I camshaft position sensor starts to go, you might feel the engine running rough or even notice it misfiring. Some days, the car might stall after starting, or you’ll see the idle jump around. Acceleration loses its snap—press the gas, and there’s less response. A check engine light is common, too. Some drivers find the car hesitant to start, or it won’t start at all. Over time, the engine burns more fuel than usual. Ignoring these warning signs makes breakdowns more likely, often at the worst moments.

Where Is The BMW 733I Camshaft Position Sensor Located?

You’ll find the BMW 733I camshaft position sensor near the front or side of the engine, next to the timing cover. It sits close to the camshaft it monitors, usually in a spot that’s tough to reach without moving other parts out of the way. Sometimes, you have to pull engine trim pieces or air ducts to spot the sensor. The owner’s manual or an engine diagram helps nail down the exact spot when you’re ready to dig in. Getting a clear view first makes the job smoother later on.

How Do I Test A BMW 733I Camshaft Position Sensor?

Start with an OBD-II scan tool to look for any camshaft sensor-related codes. If there’s a warning, a multimeter can check the sensor’s resistance and voltage. Mechanics usually test it while the engine is spinning. Low or no voltage hints the sensor’s bad. Even if the sensor checks out, look at the wires and the plug, since bad connections can cause trouble, too. Replace only what you need, and always double-check before swapping out a working sensor.

How Much Does It Cost To Replace The BMW 733I Camshaft Position Sensor?

Expect to pay between $120 and $350 for a BMW 733I camshaft position sensor replacement. The sensor alone comes in at $70 to $150, depending on the brand. Shops charge extra if the sensor’s hard to reach or other parts block access. Dealerships will be pricier than local garages. Shop around for quotes, since prices shift with labor rates and location. Swapping the sensor yourself saves money, but even with a mechanic, it’s a manageable repair on most budgets.

What Causes The BMW 733I Camshaft Position Sensor To Fail?

Heat is a big enemy for the BMW 733I camshaft position sensor. Over time, temperature swings inside the engine bay can break down the sensor’s insides. If oil leaks get near the sensor, it can short out or corrode faster. Bad wiring, age, and engine vibrations make things worse. Many problems start with small leaks or brittle wires, growing into something that knocks the sensor out completely. Keeping up with basic maintenance helps catch these problems early.
