How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my camshaft position sensor replacement?

A camshaft position sensor replacement requires minimal parts to complete:
  • Camshaft position sensor: The camshaft position sensor keeps track of the position of the camshaft and sends this information to the car’s computer system. It is the main component in the replacement, and it will usually cost you around $40 to $100.
  • Camshaft position sensor bolts: The bolts serve to secure the cam sensor in place, and they generally cost $5 to $15. 
Some of the best camshaft position sensor brands include Bosch, Standard Motor Products (SMP), ACDelco. The camshaft position sensor bolts will usually be included with the sensor when you buy it. You can purchase the parts you need from auto parts stores like AutoZone, Advance Auto Parts, or online from websites like Amazon and RockAuto.
OEM camshaft position sensors can actually be similarly priced as their aftermarket counterparts, depending on your vehicle. OEM parts are also made to fit your vehicle and often come with a warranty. 
Pro tip: If you’d rather not purchase OEM parts for your vehicle, do your research—and consult a mechanic if needed—to find reliable aftermarket parts that work for your car and your budget.
Replacement parts for your camshaft position sensor can be purchased from the following: 
  • The manufacturer/dealership: OEM parts only

How will a mechanic replace my camshaft position sensor?

To complete a camshaft position sensor replacement, a mechanic will perform the following steps:
  1. Preparation: Your mechanic will lift the hood to gain access to the camshaft position sensor and disconnect the battery.
  2. Remove the electrical connector: Next, your mechanic will remove the sensor electrical connector.
  3. Remove the camshaft position sensor: Your mechanic will remove the mounting bolts holding the sensor in place and then remove the failing camshaft position sensor.
  4. Install the new camshaft position sensor: At this point, your mechanic will install and connect a new sensor and secure it with new bolts.
  5. Reassembly: Your mechanic will insert the electrical connector and reconnect the battery.

What happens if I don’t replace my camshaft position sensor?

If you fail to replace a faulty camshaft position sensor, you could experience the following:
  • Poor fuel economy
  • Difficulty starting your vehicle
  • Stalling
  • Rough idle
  • Misfires
  • Limp mode
  • Engine damage, or even engine failure
Not replacing your camshaft position sensor can be dangerous and lead to costly repairs, so you should take your vehicle to a mechanic immediately to replace your sensor.

What is a camshaft position sensor?

The camshaft position sensor, typically located on the cylinder head or block, keeps track of the camshaft’s position relative to the crankshaft and sends this information to the car’s engine control module (ECM)—i.e., the engine computer. The control unit then uses the data sent from the camshaft position sensor to manage ignition timing so the fuel injectors fire at the correct times. The cam sensor works in tandem with a crankshaft sensor to ensure that your engine runs smoothly. 
If your vehicle’s camshaft position sensor is not working properly, the fuel injectors could remain open for longer than required, allowing too much fuel into the combustion chamber.

When should I replace the camshaft position sensor on my car?

Here are a few common signs of a camshaft position sensor problem:
  • An illuminated check engine light
  • Difficulty starting
  • Poor acceleration
  • Rough idle
  • Stalling
  • Misfires
  • Reduced fuel efficiency
  • Failed emissions test
If you have an OBD-II diagnostic scanner, the trouble code P0340 indicates a Camshaft Position Sensor “A” Circuit Malfunction. However, this code can also be tripped by issues with the crankshaft position sensor, the mass airflow sensors, or the timing belts.

How often should a camshaft position sensor be replaced?

Camshaft position sensors are made to last as long as your car, but they are exposed to intense heat from the engine and can wear down. 
There is no mileage or time limit to camshaft position sensors, so you should watch for warning signs of a bad sensor and take your vehicle to a mechanic if you suspect you need a replacement.

Can I replace my camshaft position sensor myself?

You can complete a camshaft position sensor replacement at home. The replacement is relatively simple and can be a DIY project if you have the right tools.
Keep in mind: It’s vital to your vehicle’s overall performance that the job is done correctly, so if you’re not confident in your auto repair skills, take your vehicle to a mechanic.
