Press the small tab on the connector and unplug the electrical connector by pulling it away from the sensor. It monitors the engine crankshaft position and speed and is one of the most important input … What are the common causes of code P0016 ? The ECU is able to translate this voltage into crankshaft speed. The sensor is most commonly found behind the crankshaft pulley or under the timing cover. This exchange of information ensures improved efficiency of the field injection timing and the ignition timing, which can be controlled to increase performance. The Ford Fiesta utilizes a crankshaft position sensor in order to regulate the engine timing. I have checked the trigger wheel and it is all good. I am at a lose as to what else could be the cause. The diagnostic procedure for checking a bad crankshaft sensor is more effective if you take a multi-stage approach. Oil Pan Plug Repair - How do you fix the threads? Can You point me in the right direction on how to proceed? Difficult Starting Vehicle. Crankshaft sensors are located in the crank pulley, flywheel, camshaft or directly on the crankshaft. If you notice that your car is using up more fuel than usual, this may be due to a defective crankshaft position sensor. Common mounting locations include the main crank pulley, the flywheel, the camshaft or on the crankshaft itself. Push the square drive of a ratchet or breaker bar into the hole at the end of the drivebelt tensioner arm. Mechanicbase is a blog created for all car and automotive lovers. The information generated by the crankshaft sensors is used by the engine control unit after transmission. The cost of replacing a crankshaft sensor may vary depending on geographic location, product quality, the brand used, vehicle type, and labor costs. The most common symptoms of a bad or failing crankshaft position sensor are that your vehicle may not start, or your engine will stop while driving.

If the code is between P0335 and P0338, it means that the problem is related to the crankshaft sensor. I have symptoms of a bad crank shaft sensor. Remove the 10 mm bolt. The crankshaft position sensor is nestled under the engine block just above the starter. The sensor produces an electrical voltage based on fluctuations in a magnetic field. This keeps all the parts of the engine well timed and working in concert. The crankshaft sensor is usually mounted on the engine block above the starter. If the multimeter indicates zero resistance, it means a short circuit has occurred, while infinite resistance indicates an open circuit. This article is accurate and true to the best of the author’s knowledge. You can also experience misfires as well as the illumination of your ‘check engine’ on your dashboard. The best part is, our Jeep Cherokee Crankshaft Position Sensor products start from as little as $18.76. The position of the crankshaft may vary depending on the engine model and manufacturer. Sometimes the crankshaft position sensor measures the speed of the clutch flywheel to determine the speed of the crankshaft. The crankshaft position sensor is essential to a smooth-operating engine. Along with this information is the exact rotational speed and position of the crankshaft.Depending on the make of the vehicle, the CKP information is used by the ECM to properly time the spark, and deliver the fuel, while on some relays it is only for misfire detection and doesn’t really control the timing of the spark. Hello I’m Magnus, the owner and the writer of this website. You could also use the tools and things in your workshop to replace the sensor. However, by the time the engine indicator light comes on, there may be a number of other problems that are also affecting the engine, so it is good practice to use other diagnostic techniques. Your vehicle's crankshaft position sensor, commonly abbreviated and referred to as a CPS sensor, CKP sensor, or CAS (crank angle sensor), is a key component to your engine control system. Either way, it indicates that the sensor is defective and should be replaced. When the Fiesta’s ECM determines that there is an issue with the signal coming from this sensor, it’ll throw … (Related Article: How to Jack Up Your Car - NorthAmericanMotoring.com) If you notice a loss of acceleration at high speed, this is due to a defective crankshaft sensor. Coming from above, you won't be able to see it without a mirror and some luck, so finding it by feel is the best bet. The crankshaft sensor is usually mounted on the engine block above the starter. While these Hall effect sensors give a digital signal, some crankshaft position sensors produce an analog signal. The crankshaft sensor of your vehicle needs to be in good condition to provide optimal performance and accurate reading. It measures the position of the crankshaft (for which it is sometimes called the crank angle sensor or CAS), as well as the rotational speed of the crankshaft (for which it is sometimes called the engine speed sensor, ESS, or the RPM sensor).
