In this video, you will see the process of locating and replacing both the Intake and Exhaust Camshaft Position (CMP) Sensors on a Ford Focus 2.0L engine. If your car is throwing timing-related engine codes, sputtering during acceleration, or stalling out at stoplights, this visual guide shows you exactly where to look on the engine to find both sensors and how to swap them out.
How this video helps you: The 2.0L Duratec / Ti-VCT engine uses two separate camshaft position sensors—one to track the intake side and one for the exhaust side. Because they are positioned in tight spots near the top of the engine assembly and surrounded by factory wiring looms, fuel injection lines, and vacuum hoses, they can easily blend into the background. This video points directly to their exact positions on the vehicle so you can see them clearly. You will see how to clear enough working room, how to safely release the plastic electrical locking tabs without snapping them off, and the best tools to use to remove the mounting fasteners without stripping them.
Common symptoms of a bad Camshaft Position Sensor: The intake and exhaust CMP sensors feed real-time timing data to the computer so it can manage fuel injection, ignition sparks, and the variable valve timing system. When either sensor fails or sends an erratic signal, it causes these classic issues:
- Check Engine Light & Fault Codes: A problem with the sensor circuits will instantly trigger the light, storing specific trouble codes such as P0340 / P0341 (Intake side faults) or P0365 / P0366 (Exhaust side faults).
- Engine Stumbling and Sputtering: You will notice a distinct hesitation, jerking, or severe drop in power when trying to accelerate, especially when trying to merge onto the highway.
- Extended Cranking / Hard Start: The starter motor may have to turn the engine over for several seconds longer than usual before the computer finally synchronizes the timing and allows the car to fire up.
- Rough Idle or Sudden Stalling: The car may vibrate heavily when sitting in gear at a red light or shut off completely out of nowhere, forcing you to wait for the engine bay to cool down before it restarts.
- Slashed Fuel Mileage: Because the fuel trims drop out of sync when timing data goes missing, the engine will run much less efficiently and burn through gas significantly faster.
