Camshaft actuator P0020 replacement sensor

What’s up tacoma world!? My engine light is on, the computer indicates code P0020 the “Camshaft Position "A" Actuator Circuit (Bank 2)“ is there anyone here that can help with that. Trying to replace or clean the sensor

 

P0020 - Camshaft Position "A" Actuator Circuit (Bank 2)

DESCRIPTION:
The Variable Valve Timing (VVT) system includes the ECM, OCV and VVT controller. The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil pressure supplied to the VVT controller. Camshaft timing control is performed according to engine operating conditions such as the intake air volume, throttle valve position and engine coolant temperature. The ECM controls the OCV, based on the signals transmitted by several sensors. The VVT controller regulates the intake camshaft angle using oil pressure through the OCV. As a result, the relative positions of the camshaft and crankshaft are optimized, the engine torque and fuel economy improve, and the exhaust emissions decrease under overall driving conditions. The ECM detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control. This is how the target intake valve timing is verified by the ECM.

Detection Conditions:
Open or short in OCV (bank 2) circuit (1 trip detection logic).

Trouble Areas:
•Open or short in OCV (bank 2) circuit
•OCV (bank 2)
•ECM


Monitor Description:

The ECM optimizes the valve timing using the VVT system to control the intake camshaft. The VVT system includes the ECM, the OCV and the VVT controller. The ECM sends a target duty-cycle control signal to the OCV. This control signal regulates the oil pressure supplied to the VVT controller. The VVT controller can advance or retard the intake camshaft. After the ECM sends the target duty-cycle signal to the OCV, the ECM monitors the OCV current to establish an actual duty-cycle. The ECM determines the existence of a malfunction and sets the DTC when the actual duty-cycle ratio varies from the target duty-cycle ratio.

I would first check the Oil Control Valve Filters and the Oil Control Valve operation.

 

Where are the oil control valve filters?

 

Look at the image above and here. Labled "Oil Control Valve Filter". There is one in each head.

 

Here is a good post on them.
Don’t try to reuse the old gaskets.
The system is under pressure with the engine on.
Also, I’ve heard they can be tricky to remove. As some times the get stuck and can break.

This guy is a tech, take it easy and be careful.
