To repair the Variable Valve Timing (VVT) system on a 1999 Lexus RX300, first, diagnose the issue using an OBD-II scanner to check for any trouble codes. Common repairs may involve replacing the VVT sensor, cleaning or replacing the VVT solenoid, and ensuring that the timing chain and gears are in good condition. Additionally, check the oil level and quality, as low or dirty oil can affect VVT performance. If necessary, follow the manufacturer's service manual for detailed repair procedures.

There isn't one. The components of the VVT are the PCM power train control module, 2 oil control valves, an oil filter for each OCV, and an intake camshaft sprocket/actuator assembly. If your check engine light is on and it's pointing toward VVT issues I would check each OCV filter screen. That is often the culprit.
It depends on the year of your RX. 2000 and older it is a VVT malfunction. VVT stands for variable valve timing. Check the filter screens on both your oil control valves, this is often the root of VVT issues. If it is 2001 and newer it is a Control Ignition or Misfire code. Hope that helps.

DTC code P1351 typically indicates an issue with the variable valve timing (VVT) system, often related to the VVT sensor or the timing control circuit. To fix this code, start by inspecting the VVT sensor and its wiring for damage or loose connections. If the sensor appears functional, check the oil level and quality, as low or dirty oil can affect VVT operation. If necessary, replace the faulty sensor or repair any wiring issues, and clear the code using an OBD-II scanner to see if it returns.

Code P1350 on a 1999 Cadillac Seville with a 4.6L engine indicates a problem with the Ignition Control Module (ICM) or the crankshaft position sensor, affecting ignition timing. Code P1375 refers to a fault in the engine's variable valve timing (VVT) system, often related to the VVT actuator or solenoid. Both codes suggest potential issues that could impact engine performance and may require diagnostic testing to identify the exact cause. It's advisable to consult a professional mechanic for proper diagnosis and repair.
