LESSON 3: POWERTRAIN
Locking Pin
The locking pin locks the camshaft in a fully advanced position when the engine is off.
The pin locks the phaser to the camshaft during startup.
After startup, oil pressure at the VCT assembly will unlock this pin, allowing VCT operation to resume.
Makes it easier to start engine.
Reduces noise on startup.
VCT does not control valve timing until the oil temperature reaches 32°F (0°C).
