problems resetting throttle body

[andrewconner]

Hi guys

Using a mates vag-com 409.1 and cable he got from ebay (that seems to convert the usb to serial) to attempt to reset the throttle body on a 1998 MkIV Golf.

When I try to do the throttle body allignment, as detailed on the ross-tech site (Using group 098 as 060 doesn't exist), it either says ERROR immediately or comes up ADP RUN for 10 secs then says ERROR.

I'm getting really frustrated :banghead: with it so hope someone can help.

The thoughts I've had on it are

1) The sample rate is usually about 1.3 - is this too low?
2) The following DTC comes up every now and again:
00282 Throttle Position Actuator
Not sure what it means but I clear it before trying the adaption
and it still doesn't work.
3) Do I need to login (11) perhaps?


Any advice you can give me would be greatly appreciated

I would try taking the TB off the car and giving it a good clean with carb cleaner to get all the carbon out (Taking care not th scratch it) then put it back together and try agian.

Should have probably mentioned, I've cleaned the tb - it was a right mess and was makin the car cut out. Now it revs at 2000-3000.

I take it it is the full version of vag com not the shareware 1?

yip, full version

It could be the TB is actually knackered, and thats why you get the error code and the alighment doesnt work.

ah.. how can i check if the throttle body is knackered??

[andrewconner]

I think I'm gonna try to concentrate on understanding the DTC.. It actually says
00282 - Throttle Position Actuator (V60)
26-00 - Output Open

Can anyone shed some light on what the "output open" part means?

Cheers

The ECU can sense the actuator's internal resistance. When it reports that the output is open, it means that it does not find a valid value for the actuator. The actuator is a winding with finite resistance - I don't know the value on your car. Either you have an open connection, the actuator has failed, or the sensing circuit in the ECU has failed.

You can see other symptoms related to this fault code on the Ross-Tech wiki

What can be done to input the value back to the ECU?? Im having this error i.e. 00282 - Output Open on my VW Jetta 1.4 AHW engine year 00.

Thanks for a prompt reply.

You cannot input the value. The ECU measures the actuator's internal resistance and checks the measured value against the prescribed range as determined by the factory. You must correct the wiring and or replace the failed component.
