This Emissions Temperature Sensor, part number 04L906088HQ from VAG, plays a crucial role in your vehicle's emission control system. It accurately measures the temperature of exhaust gases, providing vital data to the engine control unit (ECU). By monitoring exhaust gas temperature, the ECU can make real-time adjustments to fuel injection, ignition timing, and other engine parameters. This ensures that the catalytic converter operates at its most efficient temperature, reducing harmful pollutants and improving fuel economy. A malfunctioning sensor can lead to increased emissions, poor engine performance, and illuminated check engine lights. Crafted to VAG's stringent quality standards, this sensor offers durability and consistent performance. Replacing a faulty sensor with this genuine part will help restore your vehicle's emissions system to its intended functionality, ensuring compliance with environmental regulations and maintaining a smooth-running engine.
