Component Location Overview
In this video, I provide a clear and direct look at the location of the Intake and Exhaust Camshaft Position (CMP) sensors for the 2015–2018 Lincoln MKC with the 2.0L EcoBoost engine. On this turbocharged platform, you will find these sensors mounted at the top of the cylinder head, near the timing cover/valve cover area. Because this is a dual overhead cam (DOHC) engine, you will have one sensor for the intake side and one for the exhaust side. This guide will help you distinguish between the two, which is essential for diagnosing specific bank or timing-related codes.
Benefits for DIY Repairs
Camshaft position sensor faults are a common source of performance issues in the 2.0L EcoBoost. When one fails, the Engine Control Module (ECM) loses the ability to precisely track camshaft timing, which can trigger a “Check Engine” light and cause the vehicle to enter a performance-limited “limp mode.” Replacing these sensors yourself is a straightforward process that requires minimal tools. By performing this repair, you avoid the high cost of dealership diagnostic and labor fees, and you can get your MKC back to its full, turbocharged performance levels.
Common Symptoms of Failure
A faulty CMP sensor often leads to issues related to engine timing and fuel efficiency:
- Check Engine Light: You will typically see codes like P0340, P0345 (Intake) or P0365, P0390 (Exhaust).
- Engine Stalling or Rough Idle: If the sensor signal is erratic, the engine may stumble at stoplights or fail to maintain a steady idle.
- Hard Starting: The engine may crank longer than normal because the ECM is taking extra time to figure out the engine’s position during the start-up sequence.
- Noticeable Power Loss: The engine may feel significantly less responsive, or you may experience surges in power as the computer struggles to adjust variable valve timing (VVT) effectively.
Safety Precautions
Working on the top side of the EcoBoost engine requires care for the delicate electrical and timing components:
- Engine Off: Always work with the ignition completely off. The camshaft sensors are sensitive electronic components; unplugging them while the engine is running or in “accessory” mode can risk damage to the sensor or the ECM circuit.
- Prevent Debris: The engine bay on the 2.0L EcoBoost can get dirty. Before you pull the old sensors, use compressed air or a clean brush to clear any dust or grit away from the sensor base so that no debris falls into the cylinder head.
- Use Care with O-rings: New sensors usually come with a small rubber O-ring. Ensure the O-ring is seated properly during installation; if it gets pinched, you may end up with a small oil leak at the sensor mounting point.
- Fragile Wiring: The electrical connectors have small locking tabs that can become brittle due to engine heat. Press the release tab firmly before pulling; do not force the connector, or you risk breaking the clip and causing a future loose connection.
Expert Support
I am a mechanic with extensive professional experience in automotive diagnostics and repair. The 2.0L EcoBoost timing system is precise, and sometimes these codes can also point toward VVT solenoid issues.
