ECM-280A Faulty signal
A diagnostic trouble code (DTC) stored when:
* the control module registers that the signal from the front probe is above 4.8 V for too long
* the signal from the front probe does not deviate from λ= 1
* the signal from the front probe is showing a lean fuel mixture while the signal from the rear probe is showing a rich mixture
* the signal from the front probe is showing a rich fuel mixture while the signal from the rear probe is showing a lean mixture
Enligt VIDA så ska börvvärdet från den bakre sonden vara ca 0.6V vid jämn last (t.ex. vid tomgång och genomvarm motor). Såg i dina loggar att värdet verkade ligga på 0.01V ganska ofta?
