I finally found corroded connections on the ECU... Cleaned it but still have some troubles. I think the board had already too much damages to keep it... So now i am looking for someone that has an ECU for my legacy gt 98 manual trans engine is a 2.5l twincam

What is the sending unit? I know that the speed is sent via the speed sensor to the cluster and then cluster is connverting signal to send it to ECU.... am i right or i'm missing something?

Hi Folks! I'm new here because i read about that trouble while i was searching on google to solve my problem.... Maybe someone can help me here. Since 2006 i hope that someone solved this problem and found what i was. Mine is a Legacy GT 98 Wagon with manual trans. My speedometer work fine but what i found with my obd2 reader is that the car receives weird signal causing VSS or Idle air control CEL. The ECU doesn't see any speed at all while my speedometer is working fine or seeing something but it's really erratic. I tested many wires with a ohmmeter and it seems to be ok. I found that my neutral swtich wasn't working at all, so i replaced the switch and did a test run. First run the car seemed to be repaired BUT! intermittent troubles still the worst troubles to find. The next day, i took it to go to the grocery store and BOOM CEL light come back on and the car stall at a red light. So put back the reader to see what is it and my trouble is back again. ECU receiving erratic signal or nothing. All the troubles on the car i linked to that no signal to ECU. on this pic i was rolling at 55mph constant....... that is weird! it dropped to Zero 2 seconds after that picture.
