On my fiat stilo 1.9 jtd dynamic estate, when i connect air con diagnostic shows 3 error codes and accelerator pedal don't work. I'm confused ? and when i unplug it delete all codes every thing works fine only air con don't work. All error codes in picture. Can someone help to fix it or point direction...

I think you may have to be a little clearer in what fault you have with the car as your post say initially you had a throttle problem and on clearing your fault codes the only fault you have is an Air Con fault, some of the codes could of been old stored codes held on the car ecu.

Is it just an air con fault you have now ? the air con compressor should give a click from the engine bay when you press air con button, could be number of items causing this, low gas pressure, leak in system, faulty pressure sensor, compressor fault, fuse or relay for compressor or wiring fault

I had this Exact same fault. the way i got round it ? it just to leave the Air con unplugged .

It stops the Throttle pedal working because the Air con and the Fuel pressure sensor works on the Same "Cicut" ( i think) abd wheb the Air con sensor Fails it Puts a Short in to the system , what makes the pedal stop working for some reson lol

You could buy a new Sensor what plugs in down under the bumper on the drivers side (uk) near the floor

If you have a look in my stilo progress thread theres a but better wrote up
