D) Converter light off

Question

Quizplus · Accepted Answer

Converter light off is not a typical symptom of EGR (Exhaust Gas Recirculation) system problems. EGR issues more commonly manifest as hesitation when cold, detonation (also known as engine knock or ping), and potentially increased cooling system temperature due to the engine running hotter from improper EGR function. Converter light off refers to the catalytic converter reaching its operating temperature, which is not directly related to EGR system functionality.
