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 ro...

A starter is an electric motor that turns over or "cranks" the engine to start it. It consists of a powerful DC (Direct Current) electric motor and the starter solenoid that is attached to the motor (see the picture). In most cars, a starter motor is attached to the transmission, see these photo 1  and  photo 2 .  Starter motor. Click for  larger photo The starter motor is powered by the car battery. To turn over the engine the starter motor requires a very high electric current, which means the battery has to have sufficient power. If the battery is discharged, the lights in a car might come on, but it won't be enough power (current) to turn over the starter motor. What are the symptoms of a bad starter motor: With the fully charged battery, when starting a car, nothing happens or there is a single click, but the starter motor doesn't run, even though there is a 12-Volt power at the starter control terminal. Another symptom is when the starter motor runs, ...

Starter solenoid Starter solenoid A typical starter solenoid has one small connector for the starter control wire (the white connector in the photo) and two large terminals: one for the positive battery cable and the other for the thick wire that powers the starter motor itself (see the diagram below).  The starter solenoid works as a powerful electric relay. When activated, through the control terminal, the solenoid closes the hi-current electric circuit and sends the battery power to the starter motor. At the same time, the starter solenoid pushes the starter gear forward to mesh with the  ring gear  of the engine
