Re 2002 Grand Cherokee 2.7 CRD
In desperation I am examining every sensor I can find, in an effort to put an end to the EVIC drop-out problem I am having. See my previous posts for details, Nov 11 thru Feb 12.
The Air Flow Monitor, in the air intake between the air filter and the turbo, is a Bosch "F00C 2G2 051". On the opposite face to the Part Number it has 2 metal tags that look as though something should be connected across them, but there is nothing there. One of the the tags has an "N" moulded in the casing adjacent to it.
Is there sensor wire or similar that should sit across these tags.
Just in case this little lot helps, the "on/off x3 + on" check yields (in this order): -
P1643: which is not listed in the fault codes
P0403: EGR Solenoid Cct.
P0100: Mass or Volume Air Flow Cct.
Comments from anyone who has experience of changing these parts would be much appreciated. My thoughts are that, as both the solenoids mentioned are vacuum operated it could be the vacuum system that is at fault. Are there any locations where vacuum pipes are most likely to split or perish? Is it the same vacuum circuit that operates the servo assistance on the brakes? I've not had any braking problems.
Thanks in advance.
