The crankshaft position sensor’s role is monitoring the engine’s many moving parts including the crankshaft, engine valves, and pistons. One of the most common reasons for the issue of car shuts off while driving is a faulty crankshaft position sensor. Photo credit: SellMax 7 Reasons Why Your Car Shuts Off While Driving Faulty Crankshaft Position Sensor A number of faulty parts can make your car shuts off while driving and put you in danger, so regular maintenance is key, as always. This happens when the engine is very sensitive at idle and can be caused by many things, but the most common reasons are a faulty throttle body or a lean fuel mixture that is causing the idle to drop too low. This is a different matter from when your car shuts off after you stop. In this article, we’ll deal with the issue of car shuts off while driving.

Learn the most likely culprits for car randomly shuts off, how to fix and avoid it in the future with proper car maintenance, and the steps to follow to keep yourself and others on the road safe when your car shuts off while driving in traffic. There are many reasons for this headache. Check out this article from the experts at 1A Auto to learn more about how to test a crankshaft position sensor.Having your car shuts off while driving is a dangerous situation. However, before you replace it, you might want to run some tests first to confirm that the crank sensor really is the source of the problem. If you are experiencing the problems mentioned above, then it may very well be time to replace your badĬrankshaft position sensor. Before you conclude that the crankshaft position sensor is bad, you may need to run some tests. Many of the issues mentioned above can be caused by failures in the ignition system or fuel injection system. There are a number of different problems that can cause similar symptoms to a crankshaft position sensor problem. The check engine light doesn't always come on, though, so you could be experiencing any of the above symptoms for some time before you see the warning light.

A diagnostic scan tool will show a code between P0335 and P0338. This will leave you unable to start the car.Ī failing or failed crankshaft position sensor may cause the check engine light on your dashboard to come on. If the crankshaft sensor has failed completely, and isn't sending a signal to the ECU at all, then the computer won't send any fuel to the injectors. It might be hard to get your engine started without the fuel it needs or without proper timing.

Sometimes the engine might even stall out entirely at low speed if the fuel injectors aren't giving it the fuel it needs. This is similar to the above in that it stems from poor spark timing.Īs seen with rough idling, sometimes crankshaft position sensor problems are worse at low engine speeds. You might feel that the engine runs rough or vibrates at idle, say, when you're sitting at a red light. You will feel, and maybe hear, this as a brief stutter in the engine. That is to say combustion may be disrupted. Lack of proper spark timing can cause a different problem: one or more of the cylinders may misfire. That means the engine will need to use more gas and your morning commute will use up more fuel than usual. Without accurate timing information, fuel injection won't occur as efficiently as it should. This can result in slow or uneven acceleration. Without accurate input from the crankshaft sensor, the engine control unit (ECU) can't make these adjustments as well as it should. If you think your sensor has failed, here are some common symptoms of a bad crankshaft sensor that can help you in determining whether or not it has failed.Īs the engine speeds up, there needs to be adjustments to spark timing and fuel injection.

Problems with the crankshaft position sensor will often present as problems with engine timing. There are a number of reasons why a crankshaft position sensor can fail, and a number of symptoms associated with that failure.
