Abstract

To calibrate the sensor and compensate for manufacturing tolerances a correction value is determined as follows. With the engine running with l = 1 a fuel mass mK1 and air mass flow mL1 are determined. Then, with l = 1 (lean or fat mixture) values mK2 and mL2 are measured. Based on these values the correction value for the condition l = 1 is derived
