Maybe there isn't a pressure sensor, maybe it's just the pressure switch (stops it running if under/over). Is there an ecu parameter to show pressure switch condition? Or does anyone know if 156/147 later cars should read exact pressure in system? The sensor on a 156 has 5 pins so expect it should/c...

Thanks kindly, So ECU looses odometer?? Gonna read with the abandoned alfadiag later and see if I get the same results as I'm sure at some point on some software I did see a reading for pressure but maybe just being a retard lol. Also got a door switch pack to give to local Alfa indie (cp in Dundee)...

My 156 20v jtd mjet also shows 0.0km for odometer on MES 1.3

2005 156 20v jtd (dual zone Delphi). Can connect to control unit, read codes & the parameters however every single actuator test comes back as a fail. Although I know led works, screens work, flaps work. Also wonder as MES reports, think wording like, secondary heater present (also shows actuato...

Also I notice the odometer in engine ECU is returning 0 and I am 100% sure the 16/20v jtd's record odometer reading in ECU.

No, because pin 9 would be for connecting to climate control ECU... which has things like outside temp, inside temp, sunlight, fan & flap details etc. The engine ECU has things like Aircon compressor, aircon pressure, fans etc... Regardless if I didn't have correct adapter\pins shorted then I wo...

Was wondering if you could help, Got MES 1.3 plugged in to 2005 156 20v jtd mjet and I'm trying to read the aircon gas pressure. Unfortunately it does not return any value at all. I guess it's not my car as my friend also tried to do same in his 2007 147 1.9 jtdm with his copy of FES and got same re...
