A failing sensor can cause intermittent problems: a car may cut out or stall randomly, but then restart with no problems. The engine might have troubles starting in wet weather, but starts OK after. Sometimes you might see the RPM gauge behaving erratically. In some cases, a failing sensor can cause long crank time before the engine starts. If the sensor is bad, the engine will crank but won't start. Read more: Why an engine cranks but won't start: common problems . Crankshaft position sensor problems Crankshaft position sensor The most common OBDII code related to the crankshaft position sensor is P0335 - Crankshaft Position Sensor "A" Circuit . In some cars (e.g. Mercedes-Benz, Nissan, Chevy, Hyundai, Kia) this code is often caused by a failed sensor itself, although there could be other reasons, such as wiring or connector issues, damaged reluctor ring, etc. In some cars, the intermittent stalling can also be caused by a problem with the crankshaft pos

how to crankshaft position sensor is work
Ford Crankshaft position sensor (CKP) The crankshaft position sensor measures the rotation speed (RPMs) and the precise position of the engine crankshaft. Without a crankshaft position sensor the engine wouldn't start. In some cars, the sensor is installed close to the main pulley (harmonic balancer) like in this Ford in the photo. In other cars, the sensor could be installed at the transmission bell housing, or in the engine cylinder block, as in the photo below. In the technical literature, the crankshaft position sensor is abbreviated to CKP. How the crankshaft position sensor works In this GM engine, the crankshaft position sensor is installed at the cylinder block The crankshaft position sensor is positioned so that teeth on the reluctor ring attached to the crankshaft pass close to the sensor tip. The reluctor ring has one or more teeth missing to provide the engine computer (PCM) with the reference point to the crankshaft position. As the crankshaft rotates
why is the check engine light showing Suzuki Honda corolla
Updated: January 09, 2019 It's what almost every motorist has to go through once in a while: the Check Engine or Service Engine Soon light. If this warning light stays on, it means that your vehicle's computer has detected a problem that can affect your vehicle's fuel economy and emissions. Check Engine or Malfunction indicator light (MIL) Let's explore your options on how to deal with it. First, shortly how it works. Your car has a computer (in the photo) that controls the powertrain (engine and transmission). This computer is called Powertrain Control Module (PCM). It works by monitoring signals from various sensors and adjusting the engine and transmission performance for better fuel economy and lower emissions. This computer has a self-testing capability (called ON-Board Diagnostic or OBD-II). When it detects a fault with one of the systems or sensors, it turns on the Check Engine light on your dash. At the same time, it stores the fault code in its me
