A/C question with sensor codes
Hi there, i have read the articles posted and have these values..
1 73
2 98
3 53
4 44
5 118
6 191
7 14
8 134
1999 e430, warm day at 85 degrees, engine idle for 5minutes.
there is hissing from the center vents even thought the system was just recharged this week, the passenger side is colder than drivers side. system was charged up twice with about 1.0 lb freon over 1.5 months.
the dealer did a leak test and said no leaks, but then after few more days said they think the evaporator is leaking.
would the evep sensor fix the problem or is it evap sensor and a leak as well?
any help appreciated before i have to have the whole dash taken apart for the evap replacement.
Also the only Error code is E FF
The drivers side window vent and the passangers side vents seem to be similar temp but the drivers side center vent is def warmer than the passanger side vents.
I tried to do the flap tests from online, and the center flaps on high and low test didnt seem to change airflow much, the derfroster and floor vents seemed to have more of an airflow change with the flap tests. Where is the Diverter in this V8 engine for me to tap on?
thanks in advance

300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
Everything
seems to be in order except the evap sensor,it should read about 33-39F in that range plus a few degrees on the extremes.Pressure is fine at 14 it will vary.You won't get a true reading of values until the sensor is r/r then run the tests again.No use to give the duovalve a good tap with a screw driver handle yet,since the sensor it making the system shut down to prevent the evap from freezing up.Get the sensor from autohausaz.com order some oil filters an air filter get the order over 50 bucks and they ship free.If you need help with the r/r PM me and I can give you some tips.

"GOT CODES?"
once the sensor is reading a true value ,then you can track down the leak yourself.
