I have a 2016 fiat 500 the car starts and drives but there is no throttle response I scanned for any faults and came up with
P016549 sensor supply 2 ( internal electronic fault) ECM FAULT
C122186 ( abs fault )
Engine control module - signal invalid
any help information would be great

Hi

Looks like its your exhaust sensor with a P0165 error

From a forum search

The C is a PCM bus error

Being a 500..
Check the tailgate wiring.. chafes and breaks.. can cause chaos


Always worth 2 minutes adding a jumplead from battery negative to engine metal too.. a 2nd earth path
