A Guide to the Camshaft Position Sensor for the 2012-2017 Buick Verano
Experiencing stalling or a check engine light? Your Verano's camshaft position sensor could be the culprit.
- Symptoms like stalling and a check engine light are common for a failing camshaft position sensor.
- Similar symptoms can be caused by faulty camshaft actuator solenoids (VVT solenoids), a very common issue on these engines.
- Always check your oil level and condition first, as low or dirty oil can cause identical problems.
- This is a very easy and inexpensive DIY repair, with sensors located on top of the engine.
Is Your Buick Verano Running Rough?
If your 2012-2017 Buick Verano is suddenly stalling, having trouble starting, or showing a check engine light, a faulty camshaft position sensor might be the problem. This sensor is critical for your engine's timing, and when it fails, it can cause a range of noticeable issues. This guide will walk you through the symptoms, replacement costs, and what to consider when buying a new aftermarket sensor.
Common Problem: Camshaft Actuator Solenoids
It's important to note that many symptoms of a bad camshaft position sensor are identical to those of a failing camshaft position actuator solenoid, also known as a VVT solenoid. These solenoids control oil flow to adjust the camshaft timing. Diagnostic trouble codes like P0010, P0011, P0013, and P0014 often point to these solenoids rather than the sensors themselves. In many cases, replacing the solenoids resolves the issue. A mechanic can perform tests to determine which part has failed.
Symptoms of a Failing Camshaft Position Sensor
When a camshaft position sensor starts to go bad, your Verano will let you know. Here are the most common signs:
- Check Engine Light: This is often the first and most obvious sign. The ECM will detect a problem with the sensor's signal and trigger a warning light.
- Engine Stalling or Rough Idle: The engine may stall unexpectedly, run unevenly, or vibrate at a stop.
- Hard Starting: The car may crank for a long time before starting, or it may not start at all.
- Poor Acceleration: You might notice the car feels sluggish, hesitates, or lacks power when you press the gas pedal.
- Reduced Fuel Economy: Incorrect timing can cause the engine to burn more fuel than necessary.
Choosing an Aftermarket Camshaft Position Sensor
When replacing this part on your Verano, you have the choice between an original equipment manufacturer (OEM) part from a dealer and an aftermarket part. For a vehicle in this age range, a new aftermarket sensor offers a significant cost saving without a major compromise in quality for this specific component. Brands like 'Replacement' are designed to meet the original specifications and provide reliable performance for daily driving. Since the sensor is a common wear item, a quality aftermarket part provides a practical and budget-friendly solution.
Estimated Replacement Costs
| Part Type | Cost Range |
|---|---|
| New Aftermarket Sensor | $34.91 |
| New OEM Sensor | $59 - $146 |
| Shop Labor | $73 - $140 |
| Total Professional Replacement (Aftermarket Part) | $108 - $175 |
| Total Professional Replacement (OEM Part) | $132 - $286 |
Pro Tip: Check Your Oil
The variable valve timing (VVT) system in your Verano, which includes the camshaft sensors and actuators, is highly dependent on clean oil and proper oil levels. Low or dirty oil can cause symptoms that mimic a failed sensor or solenoid. Before replacing parts, always check your oil level and condition. An oil change can sometimes resolve the issue.
Frequently Asked Questions
Where are the camshaft position sensors located on a 2012-2017 Buick Verano?
On the 2.4L Ecotec engine, the two camshaft position sensors (one intake, one exhaust) are located on the top of the engine, near the front, right by the oil cap. They are held in by a single 10mm bolt each, making them very accessible.
Is this a difficult part to replace myself?
No, this is a very DIY-friendly repair. The sensors are easily accessible on top of the engine. The job requires basic tools like a 10mm socket and can typically be completed in under 30 minutes. You simply disconnect the electrical connector, remove one bolt, and pull the old sensor out.
Are there any recalls for the camshaft position sensor on the Buick Verano?
As of now, there are no specific safety recalls issued by the NHTSA for the camshaft position sensors on the 2012-2017 Buick Verano. However, GM has issued technical service bulletins (TSBs) for related components like the camshaft actuator solenoids on similar engines, which can cause the same symptoms and codes.
Should I replace both sensors at the same time?
It is not strictly necessary, but it is often recommended. Both sensors have been subjected to the same heat and wear over the same amount of time. If one has failed, the other may not be far behind. Since the parts are relatively inexpensive and located next to each other, replacing them in pairs can save you from having to do the job again in the near future.
