Update on bad throttle unit

[JohndeereG]

Apparently there have been around 60-70,000 new 03 manual trucks made. Sometime around the first of the year DC made a change by locating the throttle position sensor off of the engine and to under the driver side battery (this is affected around 14,000 trucks). Trucks with AUTOMATIC transmission are not effected: the throttle sensor is still mounted on the engine but will be moved starting with the 2004 models.



There appears to be a flaw in the sensor housing that causes the throttle to stick around 900-1100 rpms or to rev up when shifting.



My dealer just received a (temporary/permenant) replacement part today from Canada. The part had the following number 53032456AD. The mechanic seemed to believe that it was an engineering number and not a part number. Either way it is the same sensor unit found on the 4. 7 gasser.



Hope this helps

So when you shift or let off the go pedal does it return to idle right away? I know with mine it sort of hangs up at a higher RPM for a few moments. Pretty irritating, but I wondered if it was like some kind of computer thing for emissions that I couldn't do anything about.



I must have a pretty early model as the born on date is 7/15/02.
