A crankshaft sensor is an important part of your car’s engine control system. When it fails, your vehicle could experience a variety of problems, from slow acceleration to reduced fuel economy. If your crankshaft sensor is failing, you can take it to a mechanic for diagnosis and repair. It’s a simple job that is well within the skills of any experienced mechanic.
Replacement
A crankshaft sensor is a crucial part of your engine’s control system, and it needs to work properly for your vehicle to function as intended. If it goes bad, you can expect to see acceleration issues and poor fuel economy due to the powertrain control module’s lack of a reliable timing reference. Fortunately, replacing a crankshaft sensor is not a difficult or complicated job. Typically, a mechanic can replace a crankshaft sensor in about two hours.
If you own a mainstream car, the replacement will not break the bank, but the cost can climb for luxury and high-priced models. This is because the repair will involve new parts, which are usually marked up like most other repairs. Their products are tested to ensure they meet the highest standards. They also offer a wide variety of options for the automotive aftermarket.
Installation
A crankshaft sensor shop here relays critical information to your vehicle’s computerized management system. It controls ignition timing and fuel injection, among other things. There are two types of crankshaft sensors: Hall-effect and magneto-resistive (pick-up-coil type). If you don’t know which one your vehicle uses, the best way to find out is to read the manufacturer’s specifications and look up a spare part catalog. Once you’ve determined which kind your car uses, it’s time to replace the old sensor. Start by removing the sensor’s electrical connector and unplugging it from the mount.
After that, remove the mounting bolt and pull the sensor out of the mount. You’ll want to make sure the area is clean to ensure a solid seal while installing your new sensor. Now that you have your replacement sensor, it’s time to install it into the engine mount. Don’t forget to install the o-ring that came with your new sensor! This o-ring will help ensure that your engine doesn’t accidentally budge from its assigned position when you put the sensor back in.
Testing
A crankshaft sensor is a vital part of any engine that measures the position and speed of the crankshaft as it turns. It then sends this information to the engine control unit (ECU) to help it manage various aspects of your vehicle. If your crankshaft sensor is failing, it can produce a number of symptoms. For example, it may be difficult to start your car or it might refuse to start at all. It may also cause rough idling, vibrations in the engine, and cylinder misfiring problems. These symptoms can interfere with the operation of your vehicle and should be addressed immediately. SuncentAuto is a well-known online retail platform that offers quality products at competitive prices and satisfactory service.
To test a three-wire crank sensor, remove its electrical connector and probe the signal, reference volt, and ground wires with your multimeter. Make sure the readings are coherent with indications in your vehicle’s manual. If not, the crank sensor is likely faulty and needs to be replaced.
Maintenance
A crankshaft sensor keeps track of the location and rotational speed of your engine’s crankshaft, and sends it to the engine control unit (ECU) for proper adjustments based on operating conditions. If the sensor isn’t working correctly, it can cause a variety of problems for your vehicle. Rough idling, stalling and reduced fuel economy are all common symptoms of a bad crankshaft position sensor. You may also notice that your engine vibrates or grinds while idling, which is another indicator of a faulty crank sensor.
Conclusion
The lack of accurate input from a bad crankshaft sensor can also cause the engine control unit to make improper adjustments to spark timing and fuel injection. This can result in slow or uneven acceleration, which could lead to dangerous driving situations.
