As with all our products, please insure that the reference sensor / crankshaft Position Sensor on your vehicle matches the image or part number of the item listed on our catalog - Please check the engine number where required - if you do not have an engine number, please call or email us with yoour complete VIN (Vehicle Identification Number)
Crankshaft Sensor
A crank sensor, also know as a reference sensor is used to monitor the position or rotational speed of a crankshaft. This information is used by ECU (Engine Control Unit / Brain Box) to control the timing and other functions of an engine. Before the use of crank sensors the ignition distributor would have to be adjusted manually to a timing mark / position on the engine.
The crank sensor can work in conjunction with a camshaft position sensor to monitor the interaction between other engine components such as pistons and valves, which are all related to the timing of the engine. Crank sensors are made up of magnets and inductive coils, or they may be magnetically triggered semiconductor devices. They are most commonly located at the rear of the engine or by the crankshaft pulley, on the crankshaft assembly or the flywheel / ringgear.
Can't find the ignition distributor?
Many late model cars on the road now have a computer controlled ignition system where the ignition control module and the trigger device have been replaced with a crank sensor and ignition control unit. Some later vehicles have done away with the ignition distributor totally, as these ignition control units are so sophisticated and accurate that there is no need for an ignition distributor. The sensors detect the position of the crank and in turn control the the current to each separate ignition coil for each spark plug. The advantage of having a multi coil system, unlike the convention one coil system, is that when one coil would go bad your vehicle, the vehicle would be in-operative, but when say one of six coils is defective, you are still able to drive the vehicle on five coils.
| Chassis # or VIN (Vehicle Identification Number), Engine # & Production Date. |
Occasionally a part will require a VIN, engine number or production date. A chassis number or a VIN are the same thing, and are usually found on a sticker/decal on the left/drivers door post - Usually the last six or seven digits are required (A672152) and the item will either fit to or from that number. The engine number is usually stamped onto the engine block, always in a different spot. Having trouble finding your (Mercedes) engine number, please email us or call us with your VIN and we will be happy to look it up. The production date of a vehicle is also found on the drivers door post - some parts fit up to a month/year (-06/1996) and others, from a month and year (07/1996-).
