the mixture concentration value in time and change mixture thicker or thinner to make it To reach working temperature rapidly (~300°C), a resistor (4) installed in the sensor can Oxygen sensor doesn’t work under cut-off and full load condition, which is called open loop.
Recovery: If fault occurs in sensor or resistor, all information will be ignored and the whole system will
Oxygen sensor test procedure: If diagnosis tester displays signal as “lambda sensor error “, please check: —— If there is air leakage in every manifold, pipes, brake booster, exhaust gas and fuel-vapor re-cycle system. —— Spark wear and efficiency of high voltage wire insulator. —— If timing and positioning of TDC (top dead center)/rotate speed sensor is right or not. —— Tappet clearance and engine compression ratio. —— If supplied oil pressure is right or not.
