Generally, expect these sensors to be in the following vicinity:
* Crankshaft Position Sensor (CKP): This sensor is typically located on the engine block, near the crankshaft pulley at the front of the engine. It's often mounted on the transmission bell housing or a nearby surface and points toward the crankshaft's reluctor wheel.
* Camshaft Position Sensor (CMP): This sensor's location varies more between engine types. It's usually mounted on the cylinder head, near the camshaft sprocket or gear at the front of the engine. Sometimes it's on the valve cover. It's designed to detect the camshaft's position.
To find them, I strongly advise:
1. Consult a repair manual: This will give you diagrams and precise locations based on your engine.
2. Use a visual inspection: Once you've located the general area from the manual, carefully look around the front of the engine near the timing chain/belt cover. The sensors are typically easily visible once you know where to look.
3. Be cautious: Remember to disconnect the negative battery terminal before starting any work near the engine. These areas can be hot and have moving parts.
Don't hesitate to use online automotive parts stores' websites (like AutoZone, Advance Auto Parts, etc.). They often have diagrams and exploded views of engine components that can show you the sensor locations. Just enter your vehicle's year, make, model, and engine size.
