A car’s crankshaft sensor is responsible for sending signals to the engine’s computer, which in turn helps to control things like ignition and fuel injection. When this sensor goes bad, it can cause the engine to stall or not start at all. In this article, we’ll show you how to start a car with a bad crankshaft sensor using some simple troubleshooting techniques.
What Happens If the Crankshaft Sensor Fails?
The crankshaft sensor can cause a variety of symptoms if it fails. A dashboard Engine Management Light (EML) or “check engine” light is the most common symptom. Other symptoms can include:
- Poor fuel economy
- Difficulty starting the engine
- Rough idle
You should have your crankshaft sensor checked out if you experience any of these symptoms. Not replacing a failing sensor in a timely manner can cause serious engine damage.
How To Start A Car With A Bad Crankshaft Sensor?
If your car has been exhibiting signs of a bad crankshaft sensor, such as stalling or difficulty starting, then you’ll want to take some steps to diagnose and fix the problem. One way to start a car with a bad crankshaft sensor is to check the engine’s computer for codes. If there are any codes related to the crankshaft sensor, they should be able to give you a good idea of where to start your troubleshooting.
Another way to start a car with a bad crankshaft sensor is to check the wiring harness for any loose or damaged wires. If you find any, you’ll need to replace them as soon as possible. Additionally, you may need to clean or replace the crankshaft sensor itself if it’s become dirty or damaged.
