What Is the Crankshaft Position Sensor and How Does It Work?
Modern vehicles rely on computerized engine management systems that gather data from various sensors to optimize performance. The crankshaft position sensor works alongside the camshaft position sensor to control ignition timing and signal when fuel should be injected and sparks provided. Due to its location, exposure to heat and oil leaks often leads to sensor failure. At Nationwide Mechanics, we connect you with expert mobile mechanics who provide fast and reliable crankshaft position sensor diagnostics and replacement at your convenience.
Keep in Mind
Damage to the crankshaft position sensor is sometimes caused by oil leaks, which may require repairing or replacing other vehicle components. The sensor’s electrical connector can also suffer damage and should be carefully inspected during replacement.
How the Service Is Performed
- Scan the vehicle’s onboard computer for trouble codes
- Remove and replace the faulty crankshaft position sensor
- Clear error codes from the system
- Test the vehicle to ensure proper operation and performance
Our Recommendation
The crankshaft position sensor typically signals its failure through warning lights and drivability issues. If your Check Engine light comes on or your vehicle struggles to start or runs roughly, schedule an inspection promptly to avoid further damage.
Common Symptoms Indicating Crankshaft Position Sensor Replacement
- Vehicle does not start
- Check Engine warning light is illuminated
- Engine misfires or runs rough
Importance of This Service
The crankshaft position sensor provides critical data to your vehicle’s computer to manage ignition timing and fuel delivery. Without it, the engine control system cannot function properly, resulting in starting issues or engine misfires. Timely sensor replacement is vital for maintaining reliable and efficient vehicle operation.
