Will Crank Shaft Sensor Cause Car to Smoke If Bad

This article is all about the crank shaft sensor and whether or not it’s likely to cause a car to smoke if it becomes damaged. After reading this article, you’ll know everything there is to know about this sensor, including the possible causes and solutions should it go bad.

What is a Crank Shaft Sensor?

If your car’s crank shaft sensor is going bad, it could cause your car to start smoking. The sensor detects when the engine is turning and sends a signal to the computer that controls the fuel injection. If the sensor’s signal is interrupted, the computer might not be able to properly control the fuel injection system. This can result in your car burning oil and starting to smoke.

How Does a Crank Shaft Sensor Work?

A crank shaft sensor is a component located on the crankshaft of a car. When the engine is turned over, the sensor sends a signal to the vehicle’s computer, telling it how fast the crankshaft is rotating. If there is something wrong with the sensor, such as a broken wire or worn gear, the computer will misinterpret this signal and may cause the car to smoke.

What are the Symptoms of a Crank Shaft Sensor Failure?

A crank shaft sensor is a device that monitors the rotation of the crankshaft. If the sensor detects a problem with the crankshaft, it can signal the car’s computer to change gears or powertrain settings. A crank shaft sensor failure can cause a variety of symptoms, including smoke coming from the engine, decreased fuel efficiency, and even a stall. If you notice any of these signs and symptoms, it’s important to have your car checked out by a mechanic.

How to Fix a Crank Shaft Sensor Yourself

If your car is smoking, there’s a good chance the crank shaft sensor is causing the problem. This sensor monitors the engine’s revolutions per minute (RPM) and sends a signal to the car’s computer that tells it when to change gears. If something is wrong with the sensor, like it’s not picking up enough RPMs, the car will start smoking because it won’t get enough information to make a proper gear change. Here are four ways to fix a crank shaft sensor on your own:

1. Check for broken wires: One of the first things you should do if your car is smoking is check for broken wires near the crank shaft sensor. If there are any broken wires, they’ll cause the sensor to malfunction and send erroneous signals to the car’s computer. Broken wires can be fixed by replacing the entire wiring harness near the sensor.

2. Replace the crank shaft sensor: If there are no broken wires and inspection of the area around the crank shaft sensor reveals no other issues, then you may need to replace the sensor itself. This can be done by removing the dashboard cover and accessing the sensor through a hole in its housing. Once you have access to the sensor, you can replace it with a


Yes, a crank shaft sensor can cause your car to smoke if it is bad. If you have a 2006-2014 Toyota Camry or Lexus LS, the crank shaft sensor is located on the engine block near the oil pan. If this sensor is not working properly, oil may not reach the piston and could cause overheating and possibly even smoking in some cases. To test whether your crank shaft sensor is bad, you will need to do a diagnostic scan tool (DST) scan of your vehicle’s engine.
