Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Variable Valve Timing Sensor
One Variable Valve Timing (VVT) sensor is mounted in outer corner of each cylinder head, just below valve cover (oil filler cap end). Remove engine cover. Disconnect VVT sensor 2-pin connector. Measure resistance between VVT sensor terminals. Resistance should be 835-1400 ohms at 14-122°F (-10-50°C), or 1060-1645 ohms at 123-212°F (51-100°C). Replace VVT sensor if resistance is not as specified.
