The Camshaft sensor determines which cylinder is firing to establish injector synchronization and coil firing sequence in DIS systems. Crankshaft sensors set ignition timing, supply the RPM signal, and determine engine speed.
No, a crankshaft position sensor and a camshaft position sensor are two different sensors that serve different purposes.
Camshaft position sensor is also called cylinder identification sensor or phase detector. In consecutive fuel injection systems, ECU must determine which cylinder to fire next. This information is provided from the cylinder identification sensor.
A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.
There are two different crankshaft position sensors on your vehicle, one designated "A" and the other "B". Both of these sensors are mounted to the engine block.
The camshaft controls the opening and closing of valves through the combustion process, and the crankshaft takes the energy from that process and connects it to the rest of the vehicle.
Common signs of a faulty crankshaft position sensor include issues starting the vehicle, intermittent stalling, and the Check Engine Light coming on.
Can you drive without a crankshaft sensor? No. Driving without a functional crankshaft sensor is dangerous and can cause severe engine damage. If the crankshaft sensor in your car fails, you should repair or replace it quickly as possible.
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car.
P0335 is a diagnostic trouble code (DTC) for "Crankshaft Position Sensor "A" Circuit Malfunction". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Expect to pay between $200 and $400 to have a crankshaft sensor replaced. However, if you have a luxury or expensive vehicle, or one in which accessing the sensor is more difficult, the cost can climb higher or even double.
Because one turn of the camshaft completes the valve operation for an entire cycle of the engine and the four-stroke-cycle engine makes two crankshaft revolutions to complete one cycle, the camshaft turns half as fast as the crankshaft.
The camshaft position sensor is used to determine which cylinder is firing to synchronize the fuel injector and coil firing sequence.
And replacing your crankshaft position sensor isn't especially difficult—in most makes and models of cars, anyway. The crankshaft position sensor plays an important role in precisely firing your engine's ignition and fuel injection. So this isn't a repair you want to wait on!
The crankshaft position sensor is the most important of all engine management sensors, and the engine will absolutely not run without it.
Crankshaft bearing noise is also caused by low oil pressure, which damages the bearing surfaces and could eventually damage the crankshaft itself. This type of noise is usually described as a rumbling or thumping sound deep in the engine when accelerating.
Engine Runs Rough and Misfires
An erratic CKP sensor can cause the PCM to miscalculate fuel injector pulse and spark timing, resulting in an engine that runs rough and misfires. As the driver, you'll likely interpret the misfire as a subtle shaking or stumble that may intensify when the vehicle is under load.
How often do crankshaft position sensors need to be replaced? There's no set replacement interval for the crankshaft position sensor, and on many cars, the part will last the lifetime of the vehicle. It's not uncommon for it to fail, however, and the likelihood increases once you pass 100,000 miles.
