Oxidation on the oxygen sensor cable may lead to signal loss or internal electronics damage. Follow the steps below to assess the situation safely.
Possible causes
-
Old oxygen sensor leaking corrosive electrolyte
-
Prolonged exposure to high humidity
-
Galvanic corrosion at connector contacts
What to try
-
Immediately disconnect the affected oxygen sensor to prevent further damage.
-
Carefully clean visible oxidation using isopropyl alcohol.
-
Inspect the internal board and connectors for green corrosion or electrolyte residue.
-
Document the extent of the damage with clear photos for service evaluation.
Do not continue using the analyzer if corrosion is present inside the device.
