2015 Ford Explorer Camshaft Position Sensor Location
The 2015 Ford Explorer features multiple camshaft sensors located near the top of the cylinder heads, specifically at the rear of the engine near the firewall for Bank 1 and the front near the radiator for Bank 2. Finding the exact 2015 ford explorer camshaft position sensor location depends on whether you have the 3.5L V6 or the 2.0L EcoBoost engine, as both utilize Variable Cam Timing (VCT) systems with multiple sensors.
Few things are more frustrating than your reliable SUV suddenly stalling at a red light or refusing to start in your driveway. If your Ford is bucking, surging, or throwing a check engine light, you are likely dealing with a sensor synchronization issue. This guide will help you pinpoint the exact 2015 ford explorer camshaft position sensor location so you can get back on the road without an expensive trip to the dealership.
Replacing these sensors is a manageable task for most DIY mechanics, provided you have the right tools and a bit of patience. We will break down the differences between the V6 and EcoBoost layouts to ensure you are pulling the right part. By the end of this article, you will understand how to diagnose, locate, and swap these critical components safely.
Let’s dive into the engine bay and look at the specifics of your Ford’s layout. Understanding where these sensors live is the first step toward a successful repair. Whether you are prepping for an off-road trip or just keeping the family commuter running, this knowledge is essential.
Understanding the 2015 ford explorer camshaft position sensor location by Engine Type
The 2015 Ford Explorer was offered with three primary powerplants: the 3.5L Ti-VCT V6, the 3.5L EcoBoost V6, and the 2.0L EcoBoost I4. Each engine has a unique configuration for its timing sensors. On the V6 models, you are actually looking for four separate sensors because there is one for the intake and one for the exhaust on each cylinder bank.
For the standard 3.5L V6, the 2015 ford explorer camshaft position sensor location for Bank 1 is tucked away near the firewall. This is the “rear” of the engine in a transverse layout. Bank 2 is much easier to access, located on the front of the engine closer to the radiator and cooling fans. Each bank has two sensors mounted into the top of the valve cover or the side of the cylinder head.
If you own the 2.0L EcoBoost four-cylinder model, your search is slightly simpler. You only have two sensors to worry about. These are located on the driver’s side of the cylinder head, right near the vacuum pump and high-pressure fuel pump assembly. They monitor the single intake and single exhaust camshafts to ensure the powertrain control module (PCM) knows exactly where the pistons are in their cycle.
Identifying Bank 1 vs. Bank 2
In a transverse engine like the Explorer’s, identifying “left” and “right” can be confusing. Bank 1 is always the side of the engine containing cylinder number one. On the Ford 3.5L, this is the bank closest to the firewall (the back of the engine bay). Bank 2 is the bank closest to the radiator.
When you get a trouble code like P0345, it specifically refers to Bank 2. Knowing this prevents you from wasting time removing the intake plenum to reach the Bank 1 sensors when the problem is actually right in front of you. Always verify your trouble code before you start spinning wrenches.
Intake vs. Exhaust Sensor Positions
On each bank, the sensors are paired. The intake sensor is generally positioned higher or further toward the center of the “V” on V6 engines. The exhaust sensor is usually located lower or toward the outer edge of the cylinder head. They look identical, but their electrical signals are used for different timing adjustments.
It is a common mistake to swap the intake and exhaust sensors during a repair. While the parts are often interchangeable, the wiring harness pigtails are specific to each location. Ensure you mark your connectors with a piece of masking tape before unplugging them to avoid a timing correlation error later.
Common Symptoms of a Failing Camshaft Sensor
Before you go searching for the 2015 ford explorer camshaft position sensor location, you should confirm the symptoms. A failing sensor often acts up when the engine gets hot. You might notice the car starts fine in the morning but stalls after a twenty-minute drive once the internal electronics of the sensor expand and lose contact.
One of the most telling signs is a “long crank” condition. This happens when the PCM cannot immediately determine the camshaft position, so it defaults to a “limp mode” or takes longer to sync with the crankshaft sensor. You might also experience a sudden loss of power or a shuddering sensation while cruising at highway speeds.
The Check Engine Light (CEL) is your best diagnostic friend here. Use an OBD-II scanner to look for codes ranging from P0340 to P0349. These codes specifically point to circuit malfunctions or intermittent signals from the camshaft position sensors. If you see these, it is time to inspect the wiring and the sensors themselves.
Essential Tools for the Job
You don’t need a professional shop setup to handle this repair, but having the right hand tools makes a world of difference. Most Ford sensors are held in by a single 8mm or 10mm bolt. Because the space near the firewall is tight, a small 1/4-inch drive ratchet is highly recommended over a bulky 1/2-inch version.
- 1/4-inch drive ratchet with a long extension.
- 8mm and 10mm deep-well sockets.
- A flat-head screwdriver to help depress stubborn electrical connector tabs.
- Dielectric grease to protect the new connection from moisture.
- An OBD-II scanner to clear codes after the repair.
If you are working on Bank 1 (the firewall side) of a V6 Explorer, you might also need a telescoping mirror. This allows you to see the bolt head without having to climb on top of the engine. A magnetic parts tray is also a lifesaver; dropping a small 8mm bolt into the depths of the engine bay can turn a twenty-minute job into a two-hour ordeal.
Step-by-Step: Replacing the Sensor on a 3.5L V6
Once you have confirmed the 2015 ford explorer camshaft position sensor location, start by disconnecting the negative battery terminal. This is a safety essential to prevent any electrical shorts and to help the PCM “reset” its learned values. Allow the engine to cool completely, as you will be reaching near hot exhaust manifolds.
Locate the sensor on the cylinder head. Press the locking tab on the electrical connector and pull it away from the sensor. If it is stuck, do not pry it with excessive force; these plastic clips become brittle with age and heat. A gentle wiggle while pressing the tab usually does the trick.
- Remove the mounting bolt using your 8mm or 10mm socket.
- Gently twist the sensor back and forth while pulling it straight out of the cylinder head.
- Inspect the old sensor’s O-ring; if it stayed inside the hole, fish it out with a pick.
- Lubricate the O-ring on the new sensor with a drop of clean engine oil.
- Slide the new sensor into place, reinstall the bolt, and click the electrical connector back on.
Tighten the bolt until it is snug, but do not over-torque it. These bolts only require about 8-10 lb-ft of torque. Over-tightening can easily strip the threads in the aluminum cylinder head, which creates a much larger problem than a simple sensor swap. Once finished, reconnect the battery and start the engine to verify the repair.
Navigating the 2.0L EcoBoost Sensor Swap
The 2.0L engine layout is a bit more cramped due to the turbocharging plumbing. The sensors are located on the end of the cylinder head, near the high-pressure fuel pump. You may need to move some vacuum lines or plastic clips out of the way to get a clear shot at the mounting bolts.
On this engine, the sensors are very sensitive to oil contamination. If you pull the old sensor and find it covered in thick, black sludge, it might be a sign that your oil change intervals are too long. Clean the mounting surface thoroughly with a lint-free rag before inserting the new unit to ensure a proper seal.
The process remains largely the same: unplug, unbolt, and replace. However, on the EcoBoost, the wiring harness is often wrapped very tightly. Be careful not to pull on the wires themselves, as this can cause internal wire breaks that result in intermittent “ghost” codes later on. Always pull from the plastic connector body.
Why Genuine Parts Matter for Ford Sensors
When shopping for a replacement, you will see many “budget” options online. However, Ford’s VCT system is incredibly precise. Aftermarket sensors often have slightly different magnetic resistance values, which can cause the PCM to think the timing is off even when the sensor is brand new.
Using a genuine Motorcraft sensor is the best way to ensure compatibility. These sensors are designed to withstand the specific heat cycles of the Explorer’s engine bay. Saving twenty dollars on a generic part isn’t worth the risk of having to do the job twice because of a signal frequency mismatch.
If you are in a pinch and must use an aftermarket part, choose a reputable brand like Bosch or Delphi. Avoid the “no-name” sensors found on discount marketplaces. Your engine’s timing is the heartbeat of its performance; don’t compromise it with inferior electronics.
Frequently Asked Questions About 2015 ford explorer camshaft position sensor location
How many camshaft sensors does a 2015 Ford Explorer have?
The 3.5L V6 engines (both naturally aspirated and EcoBoost) have four sensors—two for each bank. The 2.0L EcoBoost four-cylinder engine has two sensors in total. Always check your engine type before purchasing parts.
Can I drive with a bad camshaft position sensor?
It is not recommended. While the car might run, it can stall unexpectedly, which is a major safety hazard in traffic. Additionally, poor timing can lead to reduced fuel economy and potential damage to your catalytic converters over time.
Do I need to reprogram the car after replacing the sensor?
No, a 2015 Ford Explorer does not require specialized programming for a camshaft sensor. However, you should clear the old trouble codes with a scanner or by disconnecting the battery so the PCM can start fresh with the new data.
Where is the Bank 1 sensor specifically located?
The 2015 ford explorer camshaft position sensor location for Bank 1 is on the passenger side of the engine, but shifted toward the rear (firewall). It is the most difficult one to reach because of the intake manifold overhang.
What is the difference between a camshaft sensor and a crankshaft sensor?
The camshaft sensor tells the computer which valves are open, while the crankshaft sensor tracks the position of the pistons. The PCM compares both signals to ensure the engine is “in time.” If they don’t match, the car won’t run correctly.
