What is the meaning of VVT-i? - 2003 Toyota Corolla

no car told 100 years of cars not even a tiny hint at all. why?
vvt years up, 2000 to now./ or Honda 1989
no idea me CSPS. ?
below 800 is hard fail fix this first. 8oo hot and 1500 cold is normal.
there are vast causes, and lots of test for me to find and I have all tools here to do so.
but matters not to you.
1: egr valve stuck open
2: ISC stuck closed
3: iac valve noT working at all.
the ECU controls idle so if way low that means for a FACT the ECU HAS NOW LOST CONTROL IF IDLE AND WILL HEARD TO HUNT THE ISC IN THE HOPE IT WAKES UP FROM THE jAMP UP.
OK? ISC+ PCM FORMS A SERVO LOOP, (ENG. TERMS) SORRY.

FOR SURE HOT 800 RPM REGULATION VIA ISC VALVE..

CAM BELT SLIPPED, NO ENGINE TOLD SO MUST ADD THIS.
VVT DEAD.SURE.
PCM IN LIMPHOME MODE , DTC LOTS FORGOT THE SCAN THE PCM AND CHECK ALL FUSES?
TBW, THROTTLE BY WIRE DEAD. AND LIMPHOME.

GROSS MISFIRE
DEAD SPARK PLUG
GROSS LEAN OR RICH FUEL MIXTURES,
IF ISC FAILS DEAD, MIX GOES RICH FROM LACK OF AIR.

no country told , matters! for sure no USA. KM speeds tell that. GUESS Australia????
down under IRON./? or the exported Austrilia to Africa.???

won't rev out (means RPM limited,means low power from engine. so means engine power is lost.
and NOT:
not transmission slip. (none told A/T or stick?)
good post, lots of causes for any kind of engine power loss
I will not pretend to guess it but in terms of physics yes.
engine has mech problem , cam belt slipping then changing back.
engine low power.
does 4LT mean 5liter engine, or 4L +LT MODEL CAR
The BA sub model falcon? IDK
wiki says

• 4.0 L Barra 182 I6 (petrol)
• 4.0 L Barra 240T I6 T (petrol)
• 4.0 L Barra E-Gas I6 (LPG)

seems there are 3 engines used, day1 sold,
gas Petrol
turbo petrol (gasoline)
and LPG (propane) gas.

deep wiki' me.
182 is 6 cylinder DOHC cam engine with pesky VVT valve timing
chain drive cam +VVT
VVT can stick so there is my first physics IDEA on engine problems.
or stick head valve.

the classic list, (means what is tested in order.) using tools.
1: good engine, means all tests pass,and VVT'
2:good spark ever do a tune up in 20 long years,spark + filters.
3: bad fuel, or bad fueling rates. , fuel pump on lasts legs. sure.
4: egr struck open ,even random they do.
5:;random bad wiring to all that.

that is my best, 12,000 miles away and blind, cant see car engine or transmission there.

This code is generic and does not specify a specific failure. This code could represent low oil level, overdue oil change, restricted or damaged VVT solenoid. Emissions can be affected by a damaged PCV valve, ignition component or a vacuum leak. Would you tell me what you have checked or found so far? How is the engine running (smooth or rough)? Does the Engine Light only turn on solid or does it flash? Let me know how things are going or if there is anything else I can do. Good luck.

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

pit is a timing issue ,could be a vvt actuator or something else in one of the timing components

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

P0330 Knock Sensor 2 Circuit (Bank 2)
P1133 Air/Fuel Ratio Sensor Circuit Response Malfunction (Bank 1, Sensor 1)
P1135 Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
P1346 VVT Sensor Range/Performance Problem (Bank 1)
P1349 VVT System Malfunction (Bank 1)
P1351 Variable Valve Timing / CMP Sensor Range / Performance
P1354 Variable Valve Timing System Fault

NOTE:Variable Valve Timing (VVT) sensor is also known as camshaft position sensor.
The Variable Valve Timing (VVT) system controls intake valve timing in response to driving conditions.

Possible causes are:

1. Incorrect valve timing P1346, P1349, P1351 & P1354
2. Faulty oil control valve P1346, P1349, P1351 & P1354
3. Faulty VVT controller assembly P1346, P1349, P1351 & P1354
4. Faulty ECM All Codes
5. Jumped timing belt All Codes
   
6. Faulty Camshaft Position Sensor P1346, P1349, P1351 & P1354
7. Faulty O2 Sensor (Bank 1, Sensor 1) P1133 & P1135

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
