The camshaft position sensor (CMP) on a 2006 Ford F-150 is located at the rear of the engine, on the passenger side near the firewall. It is typically mounted to the timing cover or the back of the cylinder head and may require some nearby components to be moved for access.
In 2006, the F-150 used modular V8 engines, primarily the 4.6L and the 5.4L. In both cases, the CMP sits near the back of the engine, toward the firewall, with the electrical connector running toward the top or rear of the engine bay. Access can vary depending on whether the upper intake plenum or other components must be removed to reach it. This guide outlines the general location and how to approach inspection or replacement safely.
Engines and typical CMP mounting
Below are the common configurations and where the CMP tends to be found on each. The general principle is the same across these engines, but exact mounting can vary slightly by model year and cylinder head type.
4.6L V8 (2-valve) location
For the 4.6L V8, the CMP is mounted on the back of the right-hand (passenger-side) cylinder head near the firewall, close to the top of the engine. The sensor’s electrical connector runs along the rear of the engine toward the harness. You may need to remove the upper intake plenum to clearly see and access it.
5.4L V8 (2-valve and 3-valve) location
For the 5.4L, the CMP is similarly located at the rear of the engine on the passenger side near the firewall, attached to the timing cover or back of the cylinder head. Some configurations may route the sensor behind the air intake, but the sensor is still at the rear of the engine and accessible from above with appropriate disassembly.
How to locate and inspect the CMP on your truck
Use these practical steps to identify the sensor position and assess its condition without damaging components. Always disconnect the battery before handling electrical connectors.
- Open the hood and locate the rear of the engine on the passenger side near the firewall.
- Look for a small sensor mounted to the timing cover or back of a cylinder head with a multi-pin electrical connector.
- If visibility is poor, you may need to remove the upper intake plenum or other nearby components to gain access to the rear of the engine.
- Inspect the connector, pins, and wiring for corrosion, fraying, or looseness. Re-seat connectors and replace damaged wiring as needed.
- Consult the vehicle’s service manual for exact torque specs and replacement procedures if you determine the sensor needs to be replaced.
Symptoms of a faulty CMP
Common warning signs include engine misfires, rough idle, stalling, poor acceleration, or a check-engine light with CMP-related codes (such as P0340/P0341 variants depending on the exact engine). If these symptoms occur, verify the sensor and its wiring with the appropriate diagnostic tooling or professional service.
Summary
On a 2006 F-150, the camshaft position sensor is normally located at the rear of the engine on the passenger side near the firewall, with the precise mounting depending on whether you have the 4.6L or the 5.4L modular V8. Access can require removing the upper intake plenum or nearby components. Use the service manual for exact location and procedures to inspect or replace the CMP safely.
