Quizplus · Accepted Answer

A corroded connector at the ECT (Engine Coolant Temperature) sensor can cause all of these issues. A poor connection at the ECT can lead to inaccurate temperature readings, causing the engine to run too rich or too lean, resulting in poor fuel economy and possibly setting a diagnostic trouble code (DTC) in the engine computer.
