code p0178

Hello, diagnostic trouble codes - such as P0178 - are sets of information that act as "clues" that act as a path to diagnose something failing with the vehicle - in this case related to engine performance or vehicle emissions controls. "Sensor low input" in this case could have to do with wiring concern or a compromised wiring connector to the sensor, as well as engine software at the powertrain control module. Additionally, you'll want to ensure you are clearing the engine processor memory - you may want to disconnect the battery for 10-15 minutes to accomplish this - then reinstall and road test to see if the concern is resolved.
