- Symptoms like stalling, rough idle, and no-start are common for a failing camshaft sensor on this Explorer.
- This is a very easy and inexpensive DIY repair, typically requiring only a single bolt to be removed.
- For electronic sensors, choosing a quality brand like Motorcraft, Delphi, Denso, or Standard Ignition is highly recommended over budget options to ensure reliability.

Is Your Explorer Stalling or Running Rough? Check the Camshaft Sensor.
If you own a 2006-2011 Ford Explorer and are experiencing issues like sudden stalling, a rough idle, difficulty starting, or poor acceleration, a failing Engine Camshaft Position Sensor is a likely culprit. This sensor provides critical data to the engine computer, and when it fails, it can cause a wide range of drivability problems. The Check Engine Light will almost certainly come on, often with diagnostic trouble codes like P0340 or P0345.
Don't Ignore the Symptoms
While you can sometimes drive with a failing camshaft sensor, it's not recommended. The risk of the engine stalling unexpectedly, especially at low speeds or in traffic, is a significant safety concern. Addressing the issue promptly prevents further complications and ensures your vehicle is reliable.
Choosing the Right Aftermarket Sensor: Quality Matters
When it comes to electronic sensors for your Ford, quality is key. While budget-friendly options are tempting, forum discussions and mechanic experience strongly suggest that cheap, no-name sensors can be unreliable and fail quickly. For a critical component like the camshaft position sensor, it's best to invest in a quality part to avoid doing the job twice.
Brand Tiers for Your Consideration:
- OEM/Premium Aftermarket (Highest Reliability): Motorcraft is the original Ford part and the benchmark for quality. Premium aftermarket brands like Delphi, Denso, NGK, and Hitachi are often original equipment suppliers to various manufacturers and are known for their reliability and precise performance. These are your best bet for a hassle-free repair.
- Reputable Aftermarket (Good Value): Brands like Standard Ignition (SMP) and Walker Products have a solid reputation in the industry and offer a good balance of quality and price. Dorman is also a popular choice, though some forum users have mixed opinions, with some finding them less durable than OEM for certain sensor types.
- Economy Brands (Use with Caution): Lower-cost brands like URO Parts or other lesser-known names might be attractive pricewise, but their long-term reliability can be a gamble. For a sensor that is relatively easy to replace, some owners might take the chance, but for peace of mind, sticking to the mid or premium tiers is recommended.
Pro Tip: Check the Connector
When you replace the sensor, take a moment to inspect the electrical connector. Look for any signs of corrosion, dirt, or damage. A bad connection can mimic the symptoms of a failed sensor. Clean it with electrical contact cleaner if necessary.

Frequently Asked Questions
Where is the camshaft position sensor located on my 2006-2011 Explorer?
On the 4.0L V6 engine, the sensor is typically located on the driver's side valve cover, towards the back of the engine near the firewall. For V8 engines, there may be two sensors, one for each cylinder bank. Always verify the specific location for your engine, as it can vary slightly.
Can I replace this sensor myself?
Yes, this is a very DIY-friendly job. It usually involves unplugging an electrical connector and removing a single bolt (often a 7mm or 8mm). The most common difficulty is access, as the sensor can be in a tight spot. The entire process should take less than 30 minutes for most people.
What are the common trouble codes for a bad camshaft sensor?
The most common codes are P0340 (Camshaft Position Sensor 'A' Circuit Malfunction Bank 1) and P0345 (Camshaft Position Sensor 'A' Circuit Malfunction Bank 2, for V8 engines). These codes point to a problem in the sensor's circuit, which could be the sensor itself, the wiring, or the connector.
Do I need to perform a 'relearn' procedure after replacing the sensor?
For the 2006-2011 Ford Explorer, a specific relearn procedure is generally not required after replacing the camshaft position sensor. After installation, you should clear the trouble codes with a scan tool. If you don't have one, disconnecting the battery for about 30 minutes may also reset the computer.
