Suzuki Grand Vitara 1.9DDiS edc16C3 P0638 dtc off and limp mode

**atd** · 25th July, 2015, 09:50 AM

Hello. Patient Suzuki grand vitara 1.9ddis edc16c3 0281015322.
Car was in limp mode, one dtc stored in ecu P0638 - throttle position actuator.
I switched off this dtc, after that no errors but car is still in limp mode.
Anybody has experience with that situation?
I read that I have to edit limp mode torque limiters.
What will be with boost regulation valve N75 after that operation? Now it doesn't move the bar.

Can I get any advice or help with switching off this swirl flap?
Thank you all for interest.
Regards

Sure we experience, and solution is easy,
Don't DTC off for throttle actuator

This is not EGR, actuator needed work, sure can remove limp mode for it but this is not solution to repair car problem..

I will try boomer file. Owner decided to delete problematic element from car. Many people have problems with flaps in 1.9ddis, you have to make adaptation with tech2, used flap could also be not as good as new one ( not so cheap ).

Check that has not gone water in the throttle actuator, Suzuki has introduced a cover for this component, the OEM Code is 13471-67J00-000.

Sorry for my bad English *_*!

Problem solved, car runs fine, thanks all for input. Big thanks to boomer.

@boomeer Yes is needed for diesel too. One of all function is protect engine.

Swirl no needed, but throttle is quite another story

**boomeer** · 28th July, 2015, 10:26 AM

Throttle is an essential part of a safe car.
If the engine goes into so-called "runaway", that is, it suddenly gains insane amount of revolutions per minute, the throttle won't stop it (because you turned it off permanently). If your car uses automatic transmission, without the throttle you have literally no way of stopping it. Except for, maybe, blocking the air intake, but it's highly possible that you won't manage to do that in time. If you have a manual gearbox you can try setting your highest gear, then pressing the brake and releasing the clutch, such action may stop the engine as well.

If you don't stop the engine runaway in time it will most likely blow up your engine.

Nice write up mate but throttle wont save you if you shift wrong gear
or if turbo blows and fills the engine with oil

The first aplication of the throttle was a anti judder valve
Lately became a part of the regeneration process , now a safety valve.....
It was always a part of conspiracy for automotive companies making money........
