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.
What else can I help you with?
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.
Where does the crank sensor plug into?
The crankshaft position sensor typically plugs into the engine control module (ECM) or the powertrain control module (PCM). It sends signals about the crankshaft's position and speed to the ECM/PCM, which uses this information for engine timing and fuel injection adjustments. The connector for the crank sensor is usually located near the crankshaft or engine block for easy access.
What does a crank sensor do on a Harley?
The crank sensor on a Harley-Davidson motorcycle monitors the position and speed of the crankshaft. It provides critical data to the engine control module (ECM), allowing for precise timing of fuel injection and ignition. This ensures optimal engine performance, efficiency, and smooth operation. If the crank sensor fails, it can lead to performance issues or prevent the engine from starting.
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.
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.
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.
Does a 1996 Pontiac firefly have a crank sensor and cam sensor?
Yes, the 1996 Pontiac Firefly is equipped with both a crankshaft position sensor and a camshaft position sensor. The crank sensor monitors the position and speed of the crankshaft, while the cam sensor does the same for the camshaft, helping the engine control module manage fuel injection and ignition timing. These sensors are crucial for the engine's performance and efficiency.
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.
Is a crank or cam positing censor the same thing?
No, a crank position sensor and a cam position sensor are not the same thing. The crank position sensor monitors the position and rotational speed of the crankshaft, which is crucial for engine timing and fuel injection. In contrast, the cam position sensor tracks the position of the camshaft, helping to manage valve timing and ensure proper engine performance. Both sensors are vital for engine management but serve different functions.
Does a 1993 dodge stealth have a crank sensor?
Yes, the 1993 Dodge Stealth is equipped with a crankshaft position sensor. This sensor is essential for the engine management system as it provides information about the position and rotational speed of the crankshaft, which is crucial for ignition timing and fuel injection. If the crank sensor fails, it can lead to performance issues or engine starting problems.
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.
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.
