Camshaft and Position Sensor Replacement Overview

Your car’s camshaft should last as long as its engine. However, accidents and breakdowns can happen. If your camshaft or camshaft sensor needs a replacement, bring your vehicle to All Tune & Lube. We specialize in engine work, and replacing camshafts is a piece of the engine. It requires a deep understanding of vehicle engines to replace camshafts and camshaft sensors. Our expert technicians have many years of experience. The first aspect of replacing your camshaft is understanding what exactly it is. There are many moving parts in your car’s engine that make it work, and the camshaft is pivotal.

What is a Camshaft?

So, what is a camshaft? Literally put, a camshaft is a shaft with cams attached to it. Cams are oval-shaped rings precisely placed on the shaft. Your camshaft’s length and number of cams are dependent on how many valves and cylinders your engine has. As your engine runs, the camshaft is responsible for rotating, opening and closing valves in the cylinder head. The oval-shaped cams press valve lifters that in turn open valves that allow your car to create combustions.

How Do I Know if My Camshaft Needs a Replacement?

As with all moving parts in your car, there is a possibility of failure. Most of the time, if your camshaft has an issue, your Check Engine Light will light up. You can then bring your car into our shop so we can run diagnostics. Your car’s computer will tell us where the issue lies through a series of misfire codes or camshaft position sensor codes. You may also notice the following signs:

  • Loss of engine power
  • Popping from tailpipe or intake
  • Backfiring
  • Tapping noise from the top part of the engine
  • Misfires

Can I Repair My Camshaft?

Due to the way camshafts are manufactured, we do not recommend repairing camshafts. It is not cost-effective or practical to repair it when you can replace it with a stronger, longer-lasting camshaft. Remember, these are high-spinning metal parts that you rely on to get you from point A to point B. You want them to be as reliable as possible.

Camshaft Position Sensor Replacement

The other main component of your camshaft is your camshaft position sensor. This is important to help ensure your engine is running properly at optimal levels. The camshaft sensor is usually located under the hood of your vehicle but varies per manufacturer. In short, the camshaft sensor locates the position of the camshaft in relation to the crankshaft. This keeps the rotating cams converting rotational energy in sync with the intake and exhaust valves to control the pressure in your engine. There are many symptoms of a bad camshaft position sensor. If you have noticed any of the following issues, bring your car in right away to All Tune & Lube:

  • Poor fuel mileage
  • Problems shifting
  • Lacking acceleration
  • Engine stalling
  • Trouble with ignition
  • Car jerking or shaking while accelerating
  • Illuminated Check Engine Light
