The camshaft position sensor is usually found on the engine block or cylinder head near the camshaft or timing cover; the exact spot varies by make and model, so consult the owner's manual or a service manual for your specific vehicle. In most cars, a small 2- to 3-wire connector leads to a sensor mounted close to the timing components.
Common mounting locations
Most modern engines share a handful of familiar mounting spots. Start your search at these likely areas.
- On or near the timing cover at the front of the engine, close to the timing belt/chain and cam gear
- Mounted on the cylinder head adjacent to one or more camshafts in DOHC designs
- Behind the valve cover in older or simpler engines where access is easier after removing the cover
- On the engine block near the crank pulley or harmonic balancer in some layouts
- On the back side of the timing cover or within the timing chain area in certain mid-/rear-mounted designs
Locations vary by manufacturer and engine layout. In many designs, the CMP sensor reads a tone wheel or reluctor on the camshaft gear or sprocket, so the sensor must be positioned to detect it accurately.
Engine configuration variations
DOHC and SOHC four-cylinder engines
In most inline-four applications, the camshaft position sensor sits at the front of the engine where it can monitor the cam gear or tone wheel. It is commonly integrated with the timing cover or mounted on the cylinder head near the camshaft(s).
- Front-facing location on the timing cover, aligned with the cam gear or tone wheel
- Nearby on the cylinder head for accessible wiring and easier service
Look for a small 2- or 3-wire connector and a compact sensor body with a sensing tip directed at the cam gear.
V6 and V8 engines
In V-configured engines, you may find one CMP sensor per bank or a single sensor positioned to monitor a central camshaft area. The exact mounting can be on the front timing cover, or on the top of a cylinder head depending on the design.
- Sensor mounted on a cylinder head near the camshaft(s) for each bank
- Sometimes located on the front timing cover near the belt/chain assembly
Dual sensors are common in some architectures, while others use a single sensor with a shared reference. Always verify with the specific service information for your vehicle.
How to locate yours on your model
To pinpoint the exact CMP sensor location for your car, follow these steps tailored to model-specific detail.
- Identify your exact year, make, model, and engine code
- Open the service manual or official repair documentation for diagrams showing the CMP sensor
- Trace the wiring harness from the valve cover or cam area toward the front of the engine to find the sensor and its connector
- Inspect common spots first: front timing cover near the belt/chain, or adjacent to the camshaft on the cylinder head
If you still can’t locate it, seek assistance from a dealership, qualified mechanic, or manufacturer technical resources to avoid damaging components during inspection.
Safety and maintenance tips
Always work with the engine off and the battery disconnected when inspecting or replacing an electrical sensor. Handle connectors gently, use proper lighting, and follow torque specifications when removing any components near the timing area. After replacement, clear any diagnostic trouble codes with an OBD-II scanner if required and verify proper sensor operation with a test drive.
Summary
The camshaft position sensor is typically found near the front of the engine—on the timing cover or the cylinder head close to the camshaft(s)—but exact placement depends on the vehicle’s make, model, and engine type. Use the owner's manual or service documentation, follow the wiring harness, and consult a professional if you’re unsure. Knowing the common locations and how to identify the correct sensor can save time and reduce risk when diagnosing timing or synchronization issues.
