What is the Crankshaft Position Sensor all about?

Many newer cars have computerized engine management systems that rely on sensors to report data to the computer. The crankshaft position sensor is used in conjunction with the camshaft position sensor to control ignition timing and to let the computer know when to inject fuel and provide spark sequence. Due to the mounting locations of this sensor, it is common for heat and oil leaks to cause this sensor to fail.

Keep in mind:

  • Damage to the crankshaft position sensor is sometimes caused by leaking oil, which means there may be another component of your vehicle that needs replacement or repair.
  • The electrical connector can also be damaged, and should be inspected every time the position sensor is replaced.

How it's done:

  • Scan the car for trouble codes.
  • Remove and replace crankshaft position sensor.
  • Clear trouble codes.
  • Check for the proper operation of the car.

Our recommendation:

The crankshaft position sensor will usually let you know when it needs replacing. The Check Engine warning light will illuminate and you may notice that your vehicle has a hard time starting or running smoothly. When you notice any of these signs, schedule an inspection.

What common symptoms indicate you may need to replace the Crankshaft Position Sensor?

  • Car does not start.
  • Check engine light is on.
  • Car misfires (car runs rough).

How important is this service?

The crankshaft position sensor relays critical information to your vehicle’s computer management system. The sensor provides the management system with the information it needs to control ignition timing, and it lets the computer know when it needs to provide sparks and fuel. Without a functioning crankshaft position sensor, the computerized management system doesn’t receive this critical information, and the vehicle will either not start, or will misfire while you’re driving it.

Mercury Mariner V6-3.0L - 75 Point Safety Inspection - Tacoma, Washington
I recently heard about "Your Mechanic". I live out of the area and needed my vehicle inspected. I checked it out online and it looked promising. I read some reviews and decided to try it. Cameron is very nice, and thorough. He used not only the equipment he brought with him, but his common sense. His equipment did not show an "error code" but he figured out the (very intermittent) problem by taking his time and ruling out other problems. He even took the time to sit with me and explain all the things he went did to come to his conclusion. I appreciate his patience and knowledge. I would recommend "Your Mechanic" and Cameron Proctor to help you with your vehicle problems. Here is what is really sold me. 1. They come to you. I was worried about finding someone in a new area and then being stuck at the "shop" while they looked at my vehicle. Cameron did his work and I did the laundry. 2. They work around your schedule. I work different shifts and most shops are not open, when I am available. 3. Upfront pricing. I didn't know what I needed and the web site was able to guide me to the right service. 4. Reasonable Prices. I know that most shop hours run in the triple digits. This service was less than $100. 5. Did I say they come to you? That service alone made the biggest impact. I don't know the area, I don't have a lot of time to sit in a garage and wait. So, when reading this review, think of all the things you could be doing while they work on your vehicle at your home, at your work or where ever you may be. Then decide for yourself whether it is worth it or not.
