Ocv circuit solution on ocv problems

You mean P0011.

Here are the causes:
Dirty Oil
- Variable Valve Timing (VVT) circuit is open or shorted
- Oil Control Valve (OCV) circuit is open or shorted
- Faulty variable valve timing (VVT)
- Faulty oil control valve (OCV)
- Damaged ECM

P0022 Toyota - Camshaft Position \'A\' Timing Over-Retarded Bank 2



























Possible causes




- Dirty Oil

- Faulty variable valve timing (VVT)

- Faulty oil control valve (OCV)

- Variable Valve Timing (VVT) harness is open or shorted

- Oil Control Valve (OCV) circuit is open or shorted

- Damaged Engine Control Module (ECM)




Tech notes



If the engine oil is clean and the VVT and OCV circuits are OK, replaced the VVT to resolve the problem.





When is the code detected?


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.


Possible symptoms


- Engine Light ON (or Service Engine Soon Warning Light)

- Lack/Loss of power

- Engine rough idle


P0022 Toyota Description


The Engine Control Module (ECM) controls the Oil Control Valve (OCV) to regulate the intake camshaft angle. As a result of the angle change, the engine timing is advance or retard. Optimizing engine timing will help the engine improve torque and fuel economy, and the exhaust emissions decrease under overall driving conditions. The Variable Valve Timing (VVT) system includes the Oil Control Valve (OCV) and VVT controller. The ECM detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control.

Camshaft Position Actuator Circuit (Bank 1)

its a variable valve timing (VVT) code. You'll likely need to take it in for diagnosis.

Possible causes include: Faulty oil control valve(OCV), open or short in VVT circuit, damaged pcm, open or short in the OCV/solenoid valve

cause you changed the wrong one. on toyotas its the opossite that is bank 1

direct FSM
btw , the ecu never knows what is bad, only the test that failed
the tech, gets to do tests in FSM to find CAUSE.

Trouble Code: P1663 (3.0L V6 VIN - Auto)
OCV Circuit Malfunction (bank 2) Trouble Code Conditions:
Open or short in oil control valve circuit
Possible Causes:

• Open or short in OCV circuit
• OCV
• ECM

OCV is the oil control valve for the VVTi system, it's located on the side of the cylinder head at the front and has an electrical connector on it, the valve may the problem but it cou;ld also be a clogged oil passage that supplies regulating pressure to the valve or the VVTi gear, the system operation can be checked by connecting an intelligent tester that can activate the system to verify if the valve is the problem, before replacing expensive parts I would make sure what the problem actually may be.

P0010 - "A" Camshaft Position Actuator Circuit (Bank 1)

A P0010 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0010 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine).

Symptoms may include:
* Check Engine Light illuminated (Malfunction Indicator Lamp)
* Rough running
* other symptoms may also be present

Causes: A code P0010 may mean that one or more of the following has happened:
* Faulty oil control valve (OCV)
* Open or short in the VVT/VCT circuit
* Open or short in the OCV / solenoid valve
* Damaged computer (PCM)

Possible Solutions: Some recommended troubleshooting and repair steps are:
* Carefully inspect the Bank 1 VVT/VCT system circuit wiring and connectors, repair as required
* With a warm engine, test the operation of the OCV, replace/repair as needed


Hope this helps to solve it (remember to rate this answer).

OBD-II Trouble Code Technical Description
A P0020-023 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020-023 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn't contain cylinder #1.

Causes…
A code P0020-023 may mean that one or more of the following has happened:

• Faulty oil control valve (OCV)
• Open or short in the VVT/VCT circuit
• Open or short in the OCV / solenoid valve
• Damaged computer (PCM)

Possible Solutions
Some recommended troubleshooting and repair steps are:

• Carefully inspect the Bank 2 VVT/VCT system circuit wiring and connectors, repair as required
• With a warm engine, test the operation of the OCV, replace/repair as needed
