Air fuel ratio sensor problems Problems with air fuel ratio sensors are common. Often a sensor gets contaminated or simply fails. In some cars, the heating element inside the sensor can stop working and cause the malfunction. For example, in many Toyota and Honda cars the code P0135 may be...
PROBLEM TO BE SOLVED: To improve the water-proof sealing ability of a sensor element by composing a rubber bush of rubber material whose 100% modulus strength after elapsing of a fixed time at a fixed temperature is higher than a specified strength, for instance, a tetrafluoroethylene-perfluoro...

A failure detection system for an air-to-fuel ratio control system executes an air-to-fuel ratio feedback control based on a first output from a first air-to-fuel ratio sensor before a catalytic converter. The system detects a feedback correction value, corrected according to a second output...
PURPOSE: To accurately detect deterioration by increasing a control constant when an output fluctuation rate of an air-fuel ratio sensor on a downstream side of a catalytic converter rhodium is small, and judging deterioration of the air-fuel ratio sensor when the state of a small sensor output...
