If this is a "fly by wire" throttle, the throttle plate may be dirty and not closing all the way at idle. This can cause a conflict in the computer between the TPS reading, and another sensor. Usually, this will cause the engine to shut down, but weird stuff can happen. Not really familiar with run time error. Ask a dealer service tech what usually sets this code.

Quick explanation of your fuel system:

An automotive fuel system consists of everything between the fuel tank and the carburetor or fuel injection unit. This includes the tank itself, all the lines, one or more fuel filters, a fuel pump (mechanical, electric, or both), and the carburetor or fuel injection unit.
With the exception of the carburetor or fuel injection unit, the fuel system is quite simple in operation. Fuel is drawn or pumped from the tank through the fuel line by the fuel pump, which forces it through the fuel filter, and from there to the carburetor/injection unit where it is distributed to the cylinders.

So with that info...try first to clean your spark plugs.
Next, replace your fuel filter.
After that, depending on a carburetor/fuel injection, try an additive that cleans the injectors. For the carburetor, try a half of can of what is called "Seafoam". It comes in a metal can available everywhere, including Walmart. It is worth the $6-8 and also will "dry" out your fuel from water. Very good product.

After that, get back to us and let us know how your Toyota is running.

Sounds like it is time to change the timing chain. At least pull the cover and have a close look.
Also check the plug wires to be sure there is no short in any of them. Please - take down the vin number and call the local dealer to see if there is a recall.

Best of it

Hw can i fix toyota hilux d4d 3000,2006 model cannot rev over 1500 revs

There are alot of factors that could prevent the engine from revving over 1500RPM. Some sensors like the crank angle or cam angle have to be connected in order for the engine to even start, other wiring loom plugs like the turbo controller need to be connected or the car goes into limp mode and it won't rev past a certain point.

Then there are the automatic throttle controller area wiring loom type plugs near the inter cooler, sometimes people forget to put them all back and the engine won't rev high. Making sure the vacuum pipes in this area are all connected properly, one unplugged pipe, no vacuum, the injector pump relies on the vacuum system and if it doesn't work then not enough fuel delivery, engine can't rev high. Also if the fuel rail is leaking or if the fuel filter is clogged then engine won't rev high.

Jaguar will not

Try the "clear flood" method. Hold gas pedal to the floor and crank the engine over till it starts and builds rpm and make sure you release the gas pedal in time so that you don't over rev. the engine. Then feather the pedal trying to maintain 1500rpm for one minute then let idle .

Your best bet , take it to a qualified repair shop. Need to have a professional type diagnostic tool hooked up to view engine sensor data , see what the PCM - engine computer is seeing . Check for DTC'S - diagnostic trouble code's . Your just guessing without looking at data .

if that 2000rpm is start up from cold,,,its still a bit high! but only a bit,,,should be nearer 1500rpm cold out of gear,,,,
when warm it should run at about 850---900rpm-----out of gear-
950rpm for an auto out of gear,,
in gear an auto will drop to about 850rpm so that the motor wont stall when holding the brakes down i would take the car back,, but they may wont it over night so they can set the revs up from cold,,i have a felling that auto choke is still playing up a bit
