You start by diagnosing the problem. There's more than one possible reason why this could malfunction, so you have to narrow that down first. Replacing the valve isn't going to help if the problem is in the ECM or the signal wire, after all.
The P1336 error code in a 2001 Honda CR-V typically indicates a problem with the Variable Valve Timing (VVT) system, often related to the VVT sensor or timing issues. To fix it, start by checking the VVT sensor and its wiring for any damage or disconnection. If the sensor is functioning properly, inspect the timing belt for proper alignment and wear, as misalignment can trigger this code. If necessary, replace the VVT sensor or adjust the timing belt to resolve the issue.
The P1258 trouble code typically indicates a problem with the Variable Valve Timing (VVT) system, often related to the VVT sensor or the oil control valve. To fix this code, start by checking the oil level and quality, as low or dirty oil can affect VVT operation. Next, inspect the VVT sensor and oil control valve for any signs of damage or malfunction, and replace them if necessary. Finally, clear the code and perform a test drive to ensure the issue is resolved.
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.

It is a 3.6 Liter engine with variable valve timing (VVT).
Code P1361 typically indicates an issue with the Variable Valve Timing (VVT) system, often related to the camshaft or crankshaft position sensor. To fix it, first check the electrical connections and wiring for damage or corrosion. Next, inspect the VVT solenoid and the timing chain or belt for proper alignment and wear. If necessary, replace any faulty components and clear the code to see if it reoccurs.
Yes Toyota vehicles with a 3.3L V6 engine that has VVT-i have timing belts.
what is VVT-I
VVT is located in the front of the engine cam shaft. You may need a qualified service personnell to change it.
VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota, similar in performance to the BMW's VANOS. The Toyota VVT-i system replaces the Toyota VVT offered starting in 24 December 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system. The Toyota motors CEO has been reported to have said, "VVT is the heart of every modern Toyota!"[citation needed]VVT-i, introduced in 1996, varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt, scissor-gear or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position. Adjustments in the overlap time between the exhaust valve closing and intake valve opening result in improved engine efficiency.[1] Variants of the system, including VVTL-i, Dual VVT-i, VVT-iE, and Valvematic, have followed.
On most 4 cylinder Nissans, the solenoid for the VVT is located at the front passenger side of the cylinder head.
