Understanding Your Engine: 2.3L vs. 3.5L Layouts
Before you start popping clips and unscrewing bolts, you must identify which engine sits under your hood. The 2016 Ford Explorer came with three main options: the 2.3L EcoBoost inline-four, the 3.5L Ti-VCT V6, and the 3.5L EcoBoost V6. Each of these has a unique topography that dictates where the sensors live.
The 2.3L EcoBoost is a compact, turbocharged engine where the sensors are relatively easy to reach at the back of the cylinder head. In contrast, the 3.5L V6 models are transverse-mounted, meaning they sit sideways in the engine bay. This layout creates a “Front” bank and a “Rear” bank, which mechanics refer to as Bank 2 and Bank 1, respectively.
Knowing your engine type is crucial because the V6 models use four separate camshaft sensors—two for intake and two for exhaust. The 2.3L model uses only two. Mixing these up can lead to hours of wasted time, so take a look at your engine cover or VIN plate before proceeding with the repair.
Finding the 2016 ford explorer camshaft position sensor location on V6 Models
On the 3.5L V6 engines, the sensors are distributed across the two cylinder heads to monitor the Variable Camshaft Timing (VCT) system. Bank 1 is located at the rear of the engine bay, closest to the firewall. Bank 2 is located at the front of the engine bay, closest to the radiator.
Each bank has an intake sensor and an exhaust sensor. On Bank 1 (firewall side), the sensors are tucked away near the top of the valve cover on the passenger side. You may need to remove the plastic engine appearance cover and perhaps the air intake ducting to get a clear line of sight to these connectors.
On Bank 2 (radiator side), the sensors are much easier to spot. Look at the top of the valve cover on the driver’s side of the engine. You will see two electrical connectors plugged into the top of the head. These are held in by a single 8mm or 10mm bolt and are prone to oil seepage over time, which can interfere with the signal.
Identifying Intake vs. Exhaust Sensors
It is easy to get confused when looking at four identical-looking sensors. On the 3.5L engine, the Intake sensors are typically located closer to the center of the “V” of the engine. These monitor the camshafts that control the air coming into the cylinders.
The Exhaust sensors are located further toward the outer edges of the cylinder heads. If your OBD-II scanner gives you a code like P0345 (Bank 2), you are looking at the radiator-side head. If it specifies “Exhaust,” look for the sensor furthest from the intake manifold.
Always double-check the wire colors on the harness if you are unsure. Ford often uses specific color stripes to distinguish between the intake and exhaust circuits. Consulting a wiring diagram for your specific trim level can prevent you from replacing a perfectly good sensor by mistake.
Locating the Sensor on the 2.3L EcoBoost Engine
If you own the four-cylinder model, the 2016 ford explorer camshaft position sensor location is slightly different and arguably more cramped. These sensors are located at the rear of the cylinder head, near the high-pressure fuel pump. Because the engine is mounted transversely, “rear” means the side closest to the passenger-side wheel well.
You will find two sensors here: one for the intake cam and one for the exhaust cam. They are positioned vertically on the end of the head. Accessing them usually requires removing the air cleaner assembly and some of the vacuum lines that obstruct the back of the engine.
One pro tip for the 2.3L engine: be very careful with the electrical locking tabs. The heat generated by the turbocharger makes the plastic connectors extremely brittle over time. If you force the tab, it will snap, and you will need a zip-tie or a new pigtail to keep the connection secure.
Common Symptoms of a Failing Camshaft Sensor
When diagnosing issues, knowing the 2016 ford explorer camshaft position sensor location helps you rule out wiring damage versus internal sensor failure. But how do you know the sensor is the culprit in the first place? The most common sign is a “no-start” or “hard-start” condition where the engine cranks longer than usual.
You might also experience intermittent stalling. This often happens when the engine is warm. The internal magnets in the sensor can fail as they heat up, losing their ability to send a clean pulse to the Powertrain Control Module (PCM). Once the engine cools down, it might start and run fine again.
Other symptoms include a noticeable loss of engine power or “limp mode.” If the PCM cannot verify the camshaft’s position, it will retard the ignition timing to protect the engine. This results in sluggish acceleration and poor fuel economy. If you see a P0340 or P0365 code, it is time to inspect the sensors.
Interpreting OBD-II Trouble Codes
Your Explorer’s computer is very good at telling you which sensor is grumpy. A P0340 code usually refers to the Intake sensor on Bank 1. A P0345 code points toward Bank 2. If you see “Circuit Intermittent,” it might not be the sensor itself but a loose wire or a corroded ground.
Before buying parts, clear the codes and see if they return. Sometimes a low battery or a jump-start can trigger “ghost” codes in the cam sensor circuit. If the code returns immediately after a drive cycle, you can be certain the hardware needs your attention.
Essential Tools and Safety Precautions for DIYers
Working on a 2016 Ford Explorer is straightforward, but you need the right kit. At a minimum, grab a 1/4-inch drive ratchet and a set of metric deep sockets. Most Ford cam sensors are secured with a single small bolt that requires an 8mm or 10mm socket.
Safety is paramount when working in the engine bay. Always disconnect the negative battery terminal before unplugging sensors. This prevents accidental short circuits and ensures the PCM “relearns” the sensor values once you finish the repair. Also, wait at least an hour for the engine to cool; the exhaust manifold near Bank 1 stays hot for a long time.
- Safety glasses: Protect your eyes from falling grit or engine degreaser.
- Magnetic tray: Those small 8mm bolts love to fall into the abyss of the subframe.
- Dielectric grease: Apply a tiny dab to the connector seal to keep moisture out.
- Telescoping mirror: Useful for seeing the sensors on the firewall side (Bank 1).
Step-by-Step Replacement Instructions
Once you have identified the 2016 ford explorer camshaft position sensor location for the failing unit, the replacement process is a “plug and play” affair. Start by clearing any debris around the sensor using compressed air. You do not want dirt falling into the engine through the sensor hole.
Press the locking tab on the electrical connector and pull it straight off. Do not yank on the wires. Use your ratchet to remove the mounting bolt. Once the bolt is out, gently twist and pull the sensor. It is held in by a rubber O-ring, so it might resist a little. If it is stuck, a small flathead screwdriver can help pry it up—just be careful not to gouge the aluminum head.
Before installing the new sensor, compare it to the old one. Ensure the mounting flange and the connector pin count match exactly. Lubricate the new O-ring with a drop of clean engine oil. This helps it slide in without tearing. Slide the sensor into the hole, hand-tighten the bolt, and then snug it down with the ratchet. Do not over-tighten, as these small bolts can snap easily.
Reconnect the electrical plug until you hear a distinct “click.” Finally, reconnect your battery and start the engine. The idle might be slightly erratic for the first minute as the computer adjusts to the new signal. Take a short test drive to ensure the Check Engine light stays off and the throttle response feels crisp.
Advanced Troubleshooting: When the Sensor Isn’t the Problem
Sometimes, you replace the sensor and the code remains. This is where many DIYers get frustrated. If the new sensor doesn’t fix it, inspect the wiring harness. Look for frayed wires or melted insulation, especially near the hot exhaust components. A “short to ground” in the harness will mimic a sensor failure every time.
Another possibility is sludge buildup. If the previous owner neglected oil changes, carbon deposits can coat the “tone ring” on the camshaft. This ring is what the sensor “reads.” If it is covered in gunk, the sensor cannot pick up a clear magnetic pulse. In extreme cases, a failing timing chain tensioner can cause the cam to “flutter,” triggering a correlation code.
If you have replaced the sensor and checked the wiring, but the car still stalls, it might be time to visit a professional with an oscilloscope. They can “scope” the signal to see if the wave pattern is correct. This is rare for a 2016 model, but it is a necessary step if you are chasing a persistent gremlin.
Frequently Asked Questions About 2016 ford explorer camshaft position sensor location
How many camshaft sensors does a 2016 Ford Explorer have?
The 3.5L V6 models (both naturally aspirated and EcoBoost) have four sensors. There are two on each cylinder bank—one for intake and one for exhaust. The 2.3L 4-cylinder engine has only two sensors located at the back of the cylinder head.
Can I drive with a bad camshaft position sensor?
While the car might run, it is not recommended. A failing sensor can cause the engine to stall unexpectedly, which is dangerous in traffic. It can also cause “misfires” that eventually damage your expensive catalytic converters. It is best to fix it as soon as the symptoms appear.
Where is the 2016 ford explorer camshaft position sensor location for Bank 1?
Bank 1 is the cylinder head closest to the firewall (the back of the engine bay). On the 3.5L V6, these sensors are located on the top-right side of the engine as you face it from the front bumper. You usually have to reach over the intake manifold to access them.
What is the difference between Bank 1 and Bank 2?
In Ford’s transverse V6 layout, Bank 1 contains cylinder number one and is located toward the rear (firewall). Bank 2 is the front head located toward the radiator. This distinction is vital when reading OBD-II codes to ensure you replace the correct part.
