There are multiple sensors used to control fuel injection in an engine. Depending on the year, make, and model or the vehicle, there could be upwards of 20 sensors used to determine the amount of fuel injected into an engine.
For most modern cars, the primary sensors, which the computer uses to determine fuel needs, are the Oxygen (O2), the Mass Air Flow (MAF), and the Crank/Cam positions sensors.
The O2 sensor measures the amount of oxygen in the post combustion exhaust stream, and determines if the engine is running lean (not enough fuel) or rich (too much fuel).
The MAF sensor measures the amount of air coming in through the vehicle's intake manifold, and determines the amount of fuel needed for the volume of air the engine is moving.
The Crank/Cam position sensor measures the position of either the crankshaft or the camshaft, and tells the computer if the engine is running or not; if this sensor is not working, the fuel injectors will not deliver fuel to the engine.

Where is the location of the crank position sensor on a 97 Lincoln town car?
It is located on the timing chain cover.
What makes the injectors work Getting fuel up to the pressure valve. Getting fire to the plugs. Plugs are dry. Is there a fuse that could be stopping the injectors?
Chances are your fuel pump or pressure regulator is bad, or your injection system is not working. There is a fuse for the injection system but it varies in location in every vehicle, some under hood, some in fuse box. Find the schrader valve on your fuel rail and press a pen tip to the valve (just like the air valve in your tires, have a friend try to start the car, if a small squirt or two of gas comes out of this valve when cranking you may have a bad injection control module, if no gas squirts (not dribbles) out chances are your fuel pump is dead. Common causes for a bad injection system or the injectors not operating is the crank sensor a.k.a. crank position sensor / crank angle sensor, the fuel injection system will not recognize that the engine is turning and will not activate the fuel injector units. Good luck!!
Where is the Crank Sensor in a 2001 Malibu?
The crank sensor on a 2001 Malibu is located on the bottom of the engine near the crank shaft. It monitors the rotation and speed of the crank shaft.
Does a 95 Z-28 Camaro have a crank sensor?
No, it does not have a crank sensor. the optispark (distributor) does the job that a crank and cam sensor would do for that model of Camaro. they added one for sure in 1997 I know that because I have had a 93 94 95 and 97 Camaro z28 not sure if 96 has one or not I haven't had one of those to work on but they are real easy to find on the models that have them they are located at the bottom of the timing cover and have a 3/8 bolt that holds them in.
2004 Chrysler sebring 2.4L wont start checked timing belt and it wasn't problem?
If you don't have fire at the plug, change the crank sensor first, then the coil.
What does an angle crank sensor do in a Mitsubishi Galant?
Crank angle sensor reads rpm and sends the signal to the ECU (computer) to aid in the calculation of engine rpm, ignition timing, fuel injection and crankshaft position.
Crank sensor for 1996 Plymouth breeze?
The crank sensor sends a signal to control the spark timing to the engine. If the sensor goes bad the engine may run rough or not run at all.
Where is the injection pump ckc sensor on 2001 cummins?
The injection pump crank sensor is internal to the injection pump. It is not serviceable.
Wiil the crank shaft sensor cause the engine to buck in a 2000 kia sephia?
Yes, a crank sensor is one of the major sensors used to control engine timing and cylinder firing.
What is the function of a knock sensor on a 1991 4.3 s10?
The function of the knock sensor ob a sensor on a 1991 4.3 s10 is to provide the computer the position of the crank shaft to give it the right information to get correct timing. That would be the crank position sensor. The knock sensor monitors the engine for spark knock (ping) so the ECM (Engine Control Module) can retard the timing to eliminate it.
How ECU control ignition timing in OBD ii system?
It uses several sensors on the engine. Crank posistion,knock sensor and what happenes is if the readings say there is a knock because of something like bad fuel it will send a comand to the ECM to either advance or retard the timing. the crank sensor tell the ecm were the crank is during rotation.
Cam sensor 5.7 vortec?
No cam sensor. Just a crank sensor on the bottom of the timing cover
Colorado 2.8 crank sensor?
The Colorado 2.8 crankshaft sensor and camshaft sensor work in harmony to control the spark or fuel delivery and timing. These two consist of tone and ring which passes over a magnetic sensor.
Can a camshaft sensor make a car not crank at all?
No, the engine will still crank over but will not start if this sensor is bad because it controls the fuel injection circuit.
Where is the crank sensor located on your 1995 eagle talon esi?
The crank positioning sensor is located on the opposite side of the block as the timing belt.
Why did your 2001 Chrysler PT Cruiser engine stop running?
Out of gas, failed fuel pump, alternator, timing belt, crank sensor, cam sensor, computer, etc.Out of gas, failed fuel pump, alternator, timing belt, crank sensor, cam sensor, computer, etc.
What is the location of the crank position sensor on a 1990 Firebird 3.1?
it does not have a crank position sensor. it uses the ignition control module as a crank sensor. it is in the distributor cap
