Auto electrical oxygen sensors 31422345 Lambda sensor providing electrical signals for engine control unit in Volvo vehicles​ 

Product Description:

Air flow sensor
OE NO.:   32253665 31422345

Applicable vehicle type: For Volvo

The oxygen sensor can convert the oxygen concentration in the exhaust gas into an electrical signal and transmit it to the engine control unit (ECU), providing a key basis for the closed-loop control of the fuel injection system.

Good Vehicle Usage Habits

• Avoid prolonged short-distance low-speed driving: The oxygen sensor requires a working temperature of over 300°C to function stably. Long-term short trips (such as single journeys under 5 kilometers) prevent the sensor from heating sufficiently, leading to carbon buildup and aging of internal components. If short-distance driving is frequent, periodically drive at medium to high speeds to allow the sensor to reach its operating temperature for self-cleaning.
• Prevent incomplete engine combustion: Avoid prolonged idling, revving the engine in neutral, and other such operations, as these actions increase engine carbon deposits, which then adhere to the sensor's surface. Additionally, avoid overloading to prevent engine overheating, which can damage the sensor and surrounding components.
• Timely address basic engine faults: Issues such as clogged fuel injectors, aged spark plugs, and intake system leaks cause incomplete combustion of the air-fuel mixture. Impurities in the exhaust gas accelerate sensor failure; thus, these basic components must be repaired promptly.
