How to Start a Car With a Bad Crankshaft Sensor: Ultimate Guide
When your car’s crankshaft sensor goes bad, it can be a frustrating and inconvenient issue. The crankshaft sensor is an important component in your car’s engine, as it monitors the position and rotational speed of the crankshaft. If it fails, your car may not start or may stall unexpectedly.
However, in certain situations, there are a few methods and tricks you can use to start a car with a bad crankshaft sensor. In this article, we will discuss some of the methods you can try to get your car running temporarily while you arrange for a proper repair.
Understanding the Symptoms of a Bad Crankshaft Sensor
Before delving into how to start a car with a bad crankshaft sensor, it’s crucial to understand the common symptoms of a failing crankshaft sensor. Some of the signs that indicate a faulty crankshaft sensor include:
- Engine stalling or not starting
- Intermittent starting issues
- Rough idling or misfiring
- Reduced engine performance
- Illuminated check engine light
If you notice any of these symptoms, it’s important to promptly address the issue to avoid further damage to your vehicle.

Methods to Start a Car With a Bad Crankshaft Sensor
1. Clear The Error Codes
Many modern vehicles are equipped with an onboard diagnostic system that stores error codes when a problem is detected. In some cases, a bad crankshaft sensor may trigger error codes that prevent the car from starting. Using an OBD-II scanner, you can attempt to clear the error codes to see if the car will start. Keep in mind that this is a temporary solution, and the issue will likely reoccur until the sensor is replaced.
2. Use Starter Fluid
If the engine cranks but doesn’t start, you can try using starter fluid to help ignite the fuel and start the engine. Be cautious when using starter fluid and follow the manufacturer’s instructions carefully. It’s essential to use starter fluid in a well-ventilated area and to avoid spraying it directly into the air intake to prevent potential engine damage.
3. Tap The Crankshaft Sensor
In some cases, a failing crankshaft sensor may have internal electrical connections that are intermittent. Gently tapping the sensor with a tool such as a rubber mallet can temporarily restore the connection and allow the car to start. Keep in mind that this is not a permanent solution and should only be used to move the vehicle to a safe location for repair.
4. Jump Start The Car
If your car’s battery is in good condition, jump-starting the vehicle may provide the necessary power to bypass the faulty crankshaft sensor and start the engine. It’s important to follow proper jump-starting procedures to avoid damaging the vehicle’s electrical system.
5. Tow The Car To A Repair Facility
Ultimately, the best course of action when dealing with a bad crankshaft sensor is to have the vehicle towed to a qualified repair facility. Attempting to start a car with a faulty crankshaft sensor using temporary methods is not a long-term solution and may lead to further damage or safety risks. A professional mechanic can diagnose the issue and perform the necessary repairs to ensure the car runs smoothly and reliably.
