1999 Bluebird Bus International T 444 E
 
Dead Accelerator Petal
Ran fine last time it was driven. now it starts but does not have any petal just idles well.
Would it have anything to do with oil ??
Someone told me the injector pump relied on oil quality.
Dont really know where to start on this ,
Thank you william

Throttle linkage? See if can rev it at the engine...sounds like a broken cable

I am not sure about 1999 but I know that later T444e's had an electronic throttle. I have seen the throttle pedal fail causing the symptoms you described. When it happened it threw a SES light and code.

Is your service engine soon light on?

So you're sending a signal to a computer when you work the accelerator? So, like a rheostat?

Sounds like the electronic throttle pedal failed.

I HATE fly-by-wire!

is this a rear engine bus by chance? if so make sure the "rear throttle" switch (if one exists) isnt turned on... if it is then the throttle pedal is disabled... the switch would be in the engine compartmnent of a rear engine bus..

id the throttle poedal has failed most likely youll see a WARN ENGINE light on your dash lit..

I guess so...could you run a computer diagnosis then?

A proper scan tool would show a code and/or show you the PID data to see if the pedal has a signal from 0-100%

Why do you not think it is a door switch or something like that. Our bus will start and idle but the throttle does nothing if not all the criteria are met. Not so likely that the the throttle pot died unless you have rodents.

Good luck,
Later J
