Oxygen sensor above Hummer H3 2006-2009

High oxygen sensor for Hummer H32006-2009, American quality, excellent and practical, compliant with Saudi specifications and standards ⚙️💯! The listed price is for one piece. If you want to change the set, please adjust the quantity to 2. The oxygen sensor in the car, also known as O2 sensor or electrochemical sensitivity sensor (HEGO), measures the oxygen level in the exhaust system. This part plays a crucial role in ensuring the engine runs efficiently and achieves low emissions. Benefits of the oxygen sensor: 1. Improve fuel efficiency: Helps precisely adjust the fuel-air mixture burned in the cylinder, contributing to better fuel economy. 2. Reduce exhaust emissions: Helps regulate the remaining oxygen level in the exhaust, reducing environmental pollutants like nitrogen oxides (NOx) and carbon oxides (CO). Signs of a faulty oxygen sensor: 1. Increased fuel consumption: If the oxygen sensor is damaged or old, it may cause the fuel-air mixture to inflate, increasing fuel consumption. 2. Low power: Sensor damage may prevent proper adjustment of the fuel-air mixture, resulting in low power or weak response when pressing the accelerator. 3. Increased exhaust emissions: If the oxygen sensor does not measure the oxygen level in the exhaust correctly, vehicle emissions of pollutants may increase. 4. Check engine light: The engine (Check Engine) warning light may appear on the dashboard. The engine light indicates a malfunction in the engine or emissions system. The oxygen sensor plays a vital role in the emissions system, so when it is malfunctioning, it can cause the warning light to appear. The delivery time for external orders is 10-15 official working days.
