The ECU in your car is a computer that collects information from various parts of an internal combustion engine to make sure everything in the whole system is working properly in an optimal and precise manner to maximize efficiency.Ī faulty ECU can cause sudden drops in power, fuel efficiency, and spark loss, causing your car to shut off randomly and turn back on. Faulty Engine Control UnitĪnother source of problem that might lead to car shuts off while driving and an illuminated Check Engine light is a faulty Engine Control Unit (ECU) or engine control module. Although an OBD scanner might not help you pinpoint the exact issue, it’s still an excellent tool to narrow down the culprits. If you receive diagnostic trouble codes between P0335 and P0338, then your crankshaft position sensor is having a problem. One way to check if your crankshaft position sensor is faulty is by using an OBD scanner and reading the error codes from the ECU. Other common symptoms of a faulty crankshaft position sensor is that fuel efficiency will be compromised and the engine could run very rough, misfire before stalling out completely while driving. So if the crankshaft position sensor is faulty, it will send incorrect and abnormal data to the ECU, which is then relayed and causing the tachometer to start working erratically or sporadically. When the intended speed is achieved, the tachometer will stay put in its place.Īfter receiving information about the engine speed from the crankshaft position sensor, the ECU will then relay information to the tachometer. The tachometer typically increases every time you rev your engine. The tachometer is the gauge typically located next to your speedometer on your dashboard that reads the RPM’s in your car. Another sign that the crankshaft position sensor is faulty is that the tachometer isn’t working properly. If the crankshaft position sensor isn’t working properly, it can cause the check engine light to come on. A failing crankshaft position sensor cannot provide the correct information about piston positioning in the engine to the Engine Control Unit, causing a cylinder to misfire.
In short, this mechanism is essential for your engine’s optimal efficiency. It tracks the crankshaft’s velocity and location to help facilitate the optimal timing for fuel injection and ignition. 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.

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.
