The DENSO DET-0106 is an exhaust gas temperature sensor designed to provide precise readings of the temperature within your vehicle's exhaust system. Accurate exhaust gas temperature data is vital for the engine control unit (ECU) to make informed adjustments to fuel injection and ignition timing. This helps maintain peak engine efficiency and reduces the risk of damage to exhaust components. By ensuring the ECU has reliable temperature information, the DET-0106 contributes to better fuel economy and lower harmful emissions. It is engineered to meet stringent quality standards for durability and long-term performance.
