Customer Question

I have a Toyota Hilux 2010 4.0 V6 Petrol
Seems to not be opening full throttle from low revs
If you slip the clutch and release it seems to open then.
Anyway to check if it is opening or what is causing this?
Also is there anyway to increase the power KW
The FJ cruiser has the same motor and they have 200kw
The hilux is only 175kw? - how do they get this extra in the FJ
Any companies that modify this?

Hi Rick,

Any vehicle these days that has electronic throttle control (drive by wire), does not open the throttle blade to what you think initially.

The ECM looks at many things before deciding on how far to open the butterfly.

It is all in the programming.

Same engine in two different weighted vehicles can still be programmed to have different power levels.

200 is 14% above 175kw.

You should be more concerned with your driving habits from slipping the clutch than worrying about why it doesn't get full throttle at low revs.

Hope this helps.

Gary the vehicle pulls under full throttle intermittantly.
There must be a way to check this - i can feel the distinct difference in the same place same situation - there must be a problem.

Hi Rick,

Ok, sounds like you may have a problem there.

Normally for something of this nature, the engine light would come on.

If there is discrepancy with an accelerator pedal sensor input or throttle body or ECM or wiring, the vehicle will exhibit behaviour as you have described.

What fuel (make and octane) are you using?

Have you mentioned this condition to Toyota?
