Hi all, nice to meet you. I'm new to the forum. Here's the prob. For my seventh 156 I decided to buy a selespeed. When I phoned my local well known alfa independent about it they said that they just had the car for four days and there advice was to scrap it due to the selespeed. So I was mugged for a lot of money. So I'm going to try and fix it.. Here's the fes ECU ISO code: BC 07 02 80 1A FIAT drawing number: 46814000 Hardware number: Hardware version: 00 Software number: BAA01B22 Software version: 0000 Homologation number: ECU programming date: 00/00/0000 READING ERROR CODES: 1: P0720 - Transmission/Gear Sys (12) ERROR DETAILS: Battery voltage: 14.38 V Vehicle speed: 7.0 mph Engine speed: 1536 rpm Gear engaged: 1 Desired gear: 1 Gearbox oil temperature: 12.8 °C A/T Output Speed Sensor Circuit fault The reason for this fault is that ECU did not receive signal from the sensor. The fault is present now. Take appropriate action to fix this sensor fault. Dashboard warning light was activated for this fault. Now I'm going to have a fiddle in the morning. The fes seems straight forward enough except the car was not moving. Just wondering if it thinks I'm doing 7 mph when I'm parked could this throw a different light on it. I would really appreciate any help on this mater. By the way I can get 1st 2nd r and n.
