Where is the coolant temperature sensor located on the Beijing Hyundai Elantra?
1 Answers
Hyundai Elantra's coolant temperature sensor is located at the front end of the engine's water inlet pipe. Most vehicles use water-cooled engines, which rely on coolant circulating continuously within the engine for heat dissipation, thus requiring a coolant temperature sensor. Functions of the automotive coolant temperature sensor: 1. Adjust fuel injection quantity - increases fuel injection during low temperatures. 2. Adjust ignition timing - advances ignition timing during low temperatures and retards it during high temperatures to prevent knocking. 3. Influence idle control valve - during low temperatures, the ECU controls the idle control valve based on the coolant temperature sensor signal to increase idle speed.
