30774700 Auto Electrical lambda sensor Wide range oxygen sensors that enable precise measurement of air fuel mixtures in vehicles 

Product Description:

Air flow sensor
OE NO.:  31319665 30774700

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.

A malfunction of the oxygen sensor will directly affect the engine ECU's precise control over the air-fuel ratio, thereby causing a series of vehicle operation abnormalities.

Decline in power performance

• Weak acceleration: A distorted oxygen sensor signal prevents the ECU from matching the optimal fuel injection volume. Both a rich or lean air-fuel mixture reduce engine combustion efficiency, resulting in slow vehicle acceleration when pressing the accelerator, and may even cause a "stuffy engine" phenomenon.
• Unstable power output: When the sensor signal drifts or responds with delay, the ECU frequently adjusts the fuel injection volume, causing the engine power to fluctuate between strong and weak. This is particularly prone to causing a jerky sensation during medium-to-high speed driving.
