Why do you need a camshaft position sensor?
The Camshaft Position Sensor is GENERALLY used in all modern Sequentially Fuel Injected engines to fine tune ignition timing and fuel injection timing after the vehicle has started. Although this article concentrates on the basics of Crankshaft Position Sensors,…
What does the crankshaft position sensor do?
In a nutshell, the Crankshaft Position Sensor’s job is to help: 1) the Ignition System produce Spark and 2) the Fuel System to start injecting gasoline into the cylinders. All this so that the vehicle’s engine will start and stay running.
Where is the crankshaft sensor on an Olds intrigue?
This crankshaft position sensor belongs to a 98 Olds Intrigue. This sensor is located behind the crankshaft pulley. C ran k shaft P osition (CKP) sensors and C a m shaft P ositions (CMP) sensors used on cars and trucks today come in all sorts of different shapes, sizes and configurations.
What does the CKP sensor tell the fuel injection computer?
More specifically, the CKP sensor produces a signal that tells the fuel injection computer or the ignition control module the exact position of the cylinder pistons as they come up or go down in the compression cycle.
What happens when crankshaft position sensor ( CKP ) fails?
If the sensor (CKP) has failed completely, then the computer won’t send any fuel to the injectors. Consequently, Leaving you unable to start the car. A Crankshaft Position Sensor (CKP) Failure may cause the check engine light on your dashboard to come on.
Can a bad camshaft sensor cause an engine to not start?
If you cannot generate a spark, then you cannot start your engine. You might not immediately assume the camshaft position sensor is to blame for an engine that won’t start. But if you take your vehicle to a repair shop, do not be surprised if the mechanic tells you that the camshaft position sensor is to blame.
What are the codes for the crankshaft position sensor?
A diagnostic scan tool could show any of the following codes: 1 P0335 Crankshaft Position Sensor A Circuit Malfunction 2 P0336 Crankshaft Position Sensor A Circuit Range/Performance 3 P0337 Crankshaft Position Sensor A Circuit Low Input 4 P0338 Crankshaft Position Sensor A Circuit High Input 5 P0339 Crankshaft Position Sensor A Circuit Intermittent
How can I tell if my crankshaft sensor is not working?
Probe the wiring connectors and measure the output voltage in AC millivolts. Typically, this reading is around 200 millivolts, but this can vary from vehicle to vehicle. Check the manufacturer’s specifications. If there is no output voltage, then, obviously, your sensor is not working.
