If you’ve ever had trouble starting your car in the morning, you’re not alone. Faulty camshaft sensors are one of the most common causes of car problems, and they’re usually easy to fix. In this article, we’ll show you how to replace a camshaft sensor on a GMC Sierra, Subaru Legacy, or Toyota Camry without having to take the car to a dealer.
What is a Camshaft Sensor?
A camshaft sensor is a device that monitors the position of the camshafts within the engine. When the sensors detect an issue with the camshafts, it will prevent the engine from starting. This is typically done to prevent damage to the engine.
How Does a Camshaft Sensor Work?
A camshaft sensor detects the position of the camshafts, which helps the engine start. A faulty camshaft sensor can cause a car to not start or to start slowly.
What to do if Your Camshaft Sensor Goes Bad
If you’re having trouble starting your car, there’s a good chance that the camshaft sensor is causing the issue. Camshaft sensors are tiny devices that sit on top of your engine’s camshafts and help control the valves. If they go bad, they can cause your car to not start or run properly. Here are some tips on how to test and fix your camshaft sensor:
First, check to see if your car will start if you simply turn the key to the “on” position and wait a few seconds. If it does, your camshaft sensor is probably fine. If not, try these steps:
1) Remove the air filter and remove the spark plug wires.
2) Swap out both of your camshaft sensors. If your car still won’t start, it means one of the sensors is bad. If it starts now, then you know which sensor is bad and can replace it.
3) If neither of the above fixes the issue, your camshaft sensor may be burnt out or broken. In this case, you’ll need to replace your entire engine assembly.
Conclusion
If your car won’t start after you’ve replaced the camshaft sensor, there are a few things you can do to try and get your car started. First, make sure the battery is fully charged and that all of the cables are plugged in correctly. Next, check for any obstructions near the coil pack (this is where the camshaft sensor resides). Finally, try verifying if the engine has spark by starting it with the key in the “off” position and then turning it to “on” as soon as it starts. If all of these steps fail to get your car started, then replacing the camshaft sensor might be your best option.
