Describe the typical locations and purpose of the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor in engines with variable valve timing.

Describe the typical locations and purpose of the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor in engines with variable valve timing.

• A. CKP near exhaust manifold; CMP near cam gear
• B. CMP near cam gear to monitor cam position for timing; CKP near crank gear/flywheel for engine speed/position; both feed ECU to coordinate ignition and injection
• C. CKP and CMP both in the oil pan
• D. CKP is for oil pressure; CMP is for coolant temperature

Answer: (B)
