What to know about the Camshaft Position Sensor:
The camshaft position sensor monitors the spot of the camshaft and reports that data to the car’s onboard computer system. This onboard computer system operates with sensors and other devices preserve the engine running. With information from the camshaft position sensor (CPS), the fuel injectors decides when to fire.
When the sensor breaks down, the computer does not know when to fire the injectors and may not fire them at all. The faulty readouts may equally throw off spark timing, that will then affect the vehicle’s fuel economy. This sensor goes in conjunction with the crankshaft position sensor to assist control ignition timing. It is possible for heat and oil leaks to make this sensor to fail,because of where the sensor is positioned.
Facts to Note:
Damage to the camshaft position sensor is usually caused by oil leaks; if this is the case, you may need another part of your car changed or fixed.
When the camshaft position sensor is changed, the alignment of the timing belt should be monitored so that no fluids leak onto the position sensor mounting area.
Some camshaft position sensors will need to have their software updated when they are fixed.
The timing belts,the mass air flow sensors, and the crankshaft position sensors can all trigger the trouble code for the camshaft position sensor.
How to Fix:
Scan test computer for trouble codes.
Pinpoint tests as per flow charts.
Remove and replace Crankshaft Position Sensor.
Clear trouble codes.
Check for proper operation and test drive car.
The camshaft position sensor isn’t examined in most regular services, but your vehicle has warning signs for when the sensor begins to fail. Because it sends information to the camshaft, when the sensor starts to fail your engine will begin to have trouble. Your engine may get a hard time turning on, running on, idling, or running smoothly. Your Check Engine warning light should light up as well.
Common symptoms indicating you may need to change the Camshaft Position Sensor:
Car stalls or does not start.
Car struggles to accelerate (does not maintain speed).
Check Engine light is on.
Car stumbles or sputters on startup.
Car runs poorly or runs rough.
Importance of this service:
The camshaft spot sensor provides valuable data about the camshaft position to the computer management system. The computer system makes use of the information from the position sensor to know when to inject more fuel. Without the sensor’s data, the computer won’t inject fuel correctly, and your car will stall or sputter.
