MODELS
This bulletin explains how to troubleshoot fault codes P2004-[ ], P2006-[ ], P2017-[ ], P2086-[ ], P2016-[ ], and P2085-[ ] by providing a special fault
tree for each P-code. Troubleshoot each fault code by solving it before moving onto the next code. If you have no codes or a code other than the above
P-codes DO NOT REPLACE THE AIR MASS SENSOR.
Requirements for ALL air mass sensor replaced under warranty:
^ Printout of all fault codes of the ME2-SFI-motor electronics (short test).
^ Freeze frame data of all fault codes stored in the ME2-SFI-motor electronics.
^ Signal voltage printout Fig. 4 (page 10) of component B2/5 (Hot film MAF sensor).
^ Returned MAF sensors without the required information will be debited back to the dealer.
