2004 Ford Focus 1M5F-12A650-BF ECU repair (bad IAT/coolant temp sensor readings)
Channel: FFcossag
Date: 25/03/2020

Bad input stage resistors and capacitors cause erratic or pegged-out readings on dashboard and scan tool, despite verifying wiring loom and sensors. Repair was verified and the vehicle is still known to be running fine as of several months after issuing the repair.
