How do you fix stuck opn timing valvecontrol solenoid?

You usually can't fix them, unless you remove the solenoid from the end of the CAM shaft. They VVT solenoid, usually jams up because of dirty oil sludge, deposits, oil not being changed as often as it should be. Some have taken the VVT apart and fixed them, search You Tube, most either buy a new one...Pretty expensive, or take it to the dealer to have it fixed, still expensive.

Will my vvt sensor cause the engine to have a slow take off ,sometimes shut off?

No... The VVT solenoid doesn't come into effect until higher RPM's. Is the check
engine light on? If so, have the codes scanned to point you in the right direction as to what might be causing this problem

I have a 2005 Toyota corolla le and I replaced the v v t solenoid and the coil packs and it still won't start the engine diagnostic s Says ignition coil a b c d primary secondary circuit

Make sure that the vvt solenoid connector and its wires are all firm and not corroded or damaged. Any one of the four igniters can be at fault but not all of the four at a time. This fault often arises when the vvti sensor connector is faulty, detached, damaged. It also happens when number 2 Ignition confirmation signal (IGF) wire or number 3 Ignition Timing (IGT) wire on any of the ignition coils is broken or disconnected at the coil connector.

P0022 for 2004 toyota sienna van

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

Jaguar s-type pulled code p1380 now you press gas and the car dosen't want to go

P0066 = air assisted fuel injection (AAI) control circuit malfunction.
P1380 = VVT Solenoid circuit malfunction bank 1
P1385 = VVT Solenoid circuit malfunction bank 2
P1380 Variable cam timing solenoid A malfunction. Bank 1 cam solenoid located underneath intake manifold. The bank 1 solenoid is under the passenger side valve cover on the V8. On the V6 it's under the valve cover as well but the intake needs to be removed.
Thanks. you can rate this solution and show your appreciation.

I was in my sister's 2004 Chevy Trailblazer and it was acting up. First the service engine soon light has been on. I was driving and the engine started revving up and down then it stopped accelerating...

The VVT (variable Valve Timing) solenoid may be dirty and will need to be cleaned or replaced. Poor maintenance (lack of oil change) will cause carbon and sludge to accumulate on the VVT screen causing the VVT to stick which will cause the issues your experiencing.
You may get lucky by trying to clean the VVT by adding a can of Seafoam to your engine oil and running it in there for the next 250 miles and then giving the Trailblazer oil and filter service with the recommended 5W-30 weight oil, anything heavier may cause the VVT not to function correctly as it is now.
Start with the simple and add Seafoam (Auto Zone, Part Source) carries the product. Service the engine oil after 250 miles, and at worst you may have to replace the VVT solenoid which is simple to do. Keep me posted if you have to replace the VVT.
Thank you for using fixya and be safe

2001 volvo s40 trouble code P0015

This is a common issue particularly with vehicles that have had some neglect to the oil change routine. The VVT solenoid on the top of the valve cover gets clogged with thickened or sludged oil.

Replace the VVT solenoid and gasket with a new unit and clear the codes.
