What is a camshaft sensor??

Answer 1

a camshaft sensor is used for ignition/fueling syncrinization. Newer cars use sequential fuel injection. The cam sensor is used to detect the position of the cam in relationship to the crankshaft. The engine computer, also known as the powertrain control module (pcm) uses a crankshaft position sensor, ckp, to locate cylinder #1 for top dead center of the compression stroke where the four strokes of an engine begins. The pcm only uses the cmp(cam position sensor) for identifying the cylinder order for the sequential fueling. IF the cam sensor fails, you will most likely lose sequential fueling and default back to batch firing(firing all fuel injectors once every two revolutions of the crankshaft). Sometimes, this can cause a hard starting condition, but should never cause a no start condition.

Answer 2

Without getting to techy, the camshaft sensors pick up camshaft rotation. In a 4 cylinder engine we know that for every 1 revolution of the crankshaft the camshaft rotates 2 times. There is 1 sensor on the crankshaft and 1 sensor on the camshaft. These sensors pick up engine rotation and monitor the duration/time between these componants and adjusts sparking and fuelling and camshaft timing if variable timing fitted. The ECU has preset parameters for these sensors and if it detects the if the sensors rotate out of time, the ECU will illuminate the MIL ( Malfunction Indicator Lamp ) The sensors can be faulty or even belt or chain deflection can be too much ie stretched. Is your car a NIssan Micra??

Answer 3

It's a sensor on the camshaft which is part of the engine electronics. There are also crankshaft sensors, and axle sensors.These tell the engine management system what to do.

Answer 4

Todays cars have several sensors(relaying info to the car computer ) to help control the timing of the fuel and spark( which has to be exact ). The cam sensor is one of two that do this and it is usually found somewhere very close to a cam gear.
Depending on the car it may help control the timing of the spark OR the fuel injectors.
Its companion sensor is called the crankshaft sensor which of course tells the computer what position the crank/pistons are at.

Answer 5

Is it camshaft with a sensor stuck on it

Answer 6

Last august i had a lot of trouble starting my vauxhall corsa and the garage found that the camshaft sensor had stopped working and they charge me £150.plus vat

Answer 7

it is the thing that tells your car when to fire

Answer 8

not a vauxhall vectra is it ?
