SOURCE: where is the linear solenoid of 2002 toyota located at?

P1765 TOYOTA - Linear Shift Solenoid Circuit Fault

This code doesn't mean anything is wrong with the shift solenoid, it just means a problem in the circuit or a shaft not sensed. You need the dealer to properly diagnose this problem.

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.

misfire. #2,4,6.
v6 , option.

did you tune it up at the 60k mile? point?
i use the real FSM on toyota for correct data.

Variable valve timing system - RH bank - malfunction
best i can tell for Toy V6 with VVT.
the vvt is failing,.
get a real FSM from toy
read the page on VVT, and 1354s
then do the tests stated there.
if vvt fails that bank retards and misfires.

Variable valve timing system?

There are two components to a Variable Valve Timing (VVT) system; if you had a Check Engine Light (CEL) come on and checked at Autozone they should be able to help you differentiate which component is failing.

The first is the Oil Control Valve (OCV) which is a solenoid attached to a spool valve. This takes an electrical signal from the Engine Control Module (ECM) and turns it into linear motion through a solenoid, which controls the spool valve, which is a fancy word for a differential hydraulic valve (meaning it generally has two outputs that it can supply full/0 pressure, full/full pressure, or 0/full pressure, or any range in between. If the ECM is the brain of your car, the OCV is the brain of your VVT.

The second component is the cam phaser (some times referred to as a cam adjuster). This is a fancy pulley attached to the end of the cam shaft in your car which allows the ECM to control the timing of your engine. Timing can either be advanced or retarded, meaning the valves in your engine (which let air and fuel into or out of your engine) open earlier or later than usual.

The OCV is typically much easier to replace because you can usually see it on the exterior of the engine (the solenoid sticks out from the head to keep the coils cool). Cam phasers them selves are a much more in depth repair; you have to remove the timing cover (and everything to get to it).

Very frequently the issue is not with the phasers themselves but with the timing chain/belt tensioners. While they are just as much of a pain to access as the phasers, they are usually a lot cheaper.

Hope this helps.
