2013 Ford F150 5.0 Crankshaft Position Sensor Location
The crankshaft position sensor on a 2013 Ford F-150 with the 5.0L Coyote engine is located on the passenger side of the engine block, near the starter motor and the transmission bell housing. Identifying this component is essential for diagnosing engine misfires, hard starting, or stalling issues that often plague high-mileage trucks.
You’ve been turning the key, but your reliable F-150 just isn’t catching like it used to. Maybe you’re out on a trail, or perhaps you’re just trying to get to work, and the engine starts sputtering or cutting out entirely without warning. You know the 5.0L Coyote is a workhorse, but even the best engines rely on precise timing data to keep the cylinders firing in perfect harmony.
When that data stream gets interrupted, your truck’s computer gets confused, leading to poor performance or a complete no-start situation. If you are tired of paying premium diagnostic fees at the dealership, you have come to the right place. We are going to walk through exactly how to find and service this critical component yourself.
In this guide, we will cover the precise 2013 ford f150 5.0 crankshaft position sensor location, the tools you need to get the job done, and the safety steps required to keep your hands (and your truck) in good shape. Let’s get your engine timing back on track so you can get back to the job site or the backcountry.
Understanding the 2013 ford f150 5.0 crankshaft position sensor location
The crankshaft position sensor (CKP) acts as the heartbeat monitor for your engine. It tracks the rotational speed and position of the crankshaft, sending this data to the Powertrain Control Module (PCM). Without this signal, the PCM cannot accurately time the spark or fuel injection, which is why a failing sensor often triggers a check engine light with codes like P0335 or P0339.
To find the 2013 ford f150 5.0 crankshaft position sensor location, you need to look toward the lower rear section of the engine. Specifically, it is bolted to the engine block on the passenger side. It sits just above the starter motor, tucked near where the engine mates to the transmission.
Because of its position, it can be difficult to see from above the engine bay. Most experienced DIYers find it much easier to access by crawling under the truck. You will likely need to move some wiring harnesses aside, but the sensor itself is held in place by a single bolt, making the actual mechanical task quite straightforward once you have clear eyes on it.
Safety Precautions Before You Start
Before you slide under your truck, safety must be your top priority. Never work on a vehicle that is only supported by a hydraulic floor jack. Always use jack stands rated for your truck’s weight to ensure the frame is securely supported.
Disconnect the negative battery terminal before you start messing with electrical sensors. This prevents accidental shorts and protects the delicate electronics in your PCM while you disconnect the sensor’s wiring harness. If the engine is hot, let it cool for at least an hour to avoid burns from the exhaust manifold or engine block.
Wear eye protection to prevent debris from falling into your eyes while working under the chassis. It is also a good idea to have a flashlight or a headlamp handy, as the area around the starter is naturally dark and shadow-prone.
Required Tools for the Job
You don’t need a massive shop full of equipment to replace this sensor. A basic metric socket set and some patience are usually enough to get the job done effectively.
- Metric socket set (specifically 8mm or 10mm for the sensor bolt)
- Ratchet and a medium-length extension
- Flathead screwdriver (for releasing the harness clip)
- Work light or LED headlamp
- Nitrile gloves to keep grease off your hands
If the bolt is particularly stubborn due to road grime or rust, keep some penetrating oil nearby. Spraying the bolt head and letting it sit for ten minutes can save you from the headache of a stripped fastener.
Step-by-Step Replacement Process
Once you are safely positioned under the truck, locate the wiring harness leading to the sensor. Squeeze the release tab on the connector and pull gently; if it is stuck, use your flathead screwdriver to carefully pry the tab outward while pulling.
Use your socket and extension to remove the single bolt holding the sensor to the engine block. Once the bolt is out, pull the sensor straight out of its mounting hole. It may have an O-ring that creates a tight seal, so a little wiggling is normal.
Before installing the new sensor, clean the mounting hole with a lint-free rag to ensure no dirt falls into the engine. Apply a tiny smear of clean engine oil to the O-ring on the new sensor to help it seat properly. Slide the new unit into place, tighten the bolt snugly—do not over-torque it—and reconnect the electrical harness until you hear a distinct click.
Troubleshooting Common Issues
Sometimes, the sensor isn’t the problem at all. If you replace the sensor and the truck still won’t start, check the wiring harness for signs of fraying or heat damage. The proximity to the exhaust and starter means that wires can occasionally melt or become brittle over time.
Check your fuses as well. A blown fuse related to the ignition system or engine management can mimic the symptoms of a bad crankshaft sensor. If you have an OBD-II scanner, clear the stored codes after the repair and take the truck for a short test drive to see if the computer registers the new sensor data.
If you are still seeing the same codes after the repair, you may be dealing with a timing chain issue or a damaged reluctor wheel inside the engine. At this point, it is wise to consult a professional mechanic or a shop manual to avoid internal engine damage.
Frequently Asked Questions About Crankshaft Position Sensors
Can I drive with a bad crankshaft position sensor?
It is not recommended. If the sensor is failing, your engine timing is compromised, which can lead to stalling in traffic, severe misfires, and potential long-term damage to your catalytic converters due to unburned fuel entering the exhaust.
Do I need to reset the computer after replacement?
While the PCM will eventually recognize the new signal, it is best practice to clear the fault codes using an OBD-II scanner. This ensures the truck immediately exits “limp mode” and returns to normal operating parameters.
How often does the 5.0L Coyote crankshaft sensor fail?
It is not a high-failure item compared to something like a spark plug, but like any electronic sensor, they can succumb to heat, vibration, and age. If you are over 150,000 miles, it is a reasonable component to inspect if you experience intermittent starting issues.
Dealing with engine sensors can be intimidating, but now that you know the 2013 ford f150 5.0 crankshaft position sensor location, you have the knowledge to handle the repair with confidence. Keep your tools organized, follow your safety protocols, and you will be back on the road in no time. Stay safe and keep your F-150 running strong!
