A barcode sticker will be attached to the air cleaner housing to make it easier to distinguish whether a new or an old HFM is installed in the engine.
When replacing an old sensor, the DME will have to be reprogrammed. This is accomplished by using the PST2 with version 9.0 installed. Version 9.0
has a tentative release date of May 1, 2000. Please note that until software version 9.0 is released; continue to use the old style HMF sensor for repairs.
The barcode sticker reads as follows:
Number
Description
996 110021 09
Old style HFM
996 110 02110
New style HFM
Note:
The numbers printed on the bar sticker are not the actual part numbers of the sensors.
The sensors are visually distinguished two ways:
1.
There are coded pegs by the electrical plug connection (see figure 1). One peg (A) indicates the old style and two pegs (N) indicates the new style.
