* Incorrect fuel mixture. The camshaft sensor helps the engine control unit (ECU) determine when to inject fuel into the cylinders. If the camshaft sensor is malfunctioning, the ECU may not inject fuel at the correct time, which can lead to a rich or lean fuel mixture. A rich fuel mixture can cause the engine to run poorly and waste gas, while a lean fuel mixture can damage the engine.
* Reduced engine performance. A bad camshaft sensor can also cause the engine to lose power and efficiency. This is because the ECU relies on the camshaft sensor to determine when to open and close the valves. If the camshaft sensor is malfunctioning, the valves may not open and close at the correct time, which can lead to reduced engine performance and gas mileage.
* Increased emissions. A bad camshaft sensor can also cause the engine to produce more emissions. This is because the ECU relies on the camshaft sensor to determine when to inject fuel into the cylinders. If the camshaft sensor is malfunctioning, the ECU may not inject fuel at the correct time, which can lead to a rich or lean fuel mixture. A rich fuel mixture can cause the engine to produce more hydrocarbons and carbon monoxide, while a lean fuel mixture can cause the engine to produce more nitrogen oxides.
In addition to these effects on gas mileage, a bad camshaft sensor can also cause the engine to stall, hesitate, or run rough. If you are experiencing any of these symptoms, it is important to have your camshaft sensor checked as soon as possible.
