Which risk increases when an internal combustion engine's exhaust temperature sensor fails low?

💡 Explanation

Low exhaust temp. signal from a defective sensor invokes open loop fueling because normal exhaust temperature feedbacks for stoichiometric adjustment are considered corrupted; therefore, excessively rich unburnt fuel exits and may damage components, rather than optimal combustion control for higher efficiency and lower emissions.
