摘要： In a sensor control apparatus (2), a GND1 terminal for signal-system circuits and a GND2 terminal for a power-system circuit are separately provided in an external circuit terminal section (31). The ground for the drive circuit of the power system and the ground for the drive circuits of the signal system are disposed independently of each other on a circuit board (20). Further, a first electrical path for connecting the circuit board (20) and an engine control unit is provided independently of a second electrical path for connecting the circuit board (20) and a battery. Therefore, even when a heater control circuit (28) is turned ON, the influence of heater current on an Ip1 cell/Vs cell control circuit (26), an Ip2 cell control circuit (27), and a CAN (Controller Area Network) circuit (29) can be suppressed. Further, since the ground for the sensor-system circuit and the ground for the CAN circuit (29) are rendered common, the layout of the ground wring can be simplified.

摘要： In an oxygen sensor control apparatus, after start of fuel cut, the weighted average Ipd of corrected values obtained by multiplying the output value of a mounted oxygen sensor by a correction coefficient Kp is obtained as a representative value Ipe, representing the corrected values in the fuel cut period (S19). In the case where the number of times the representative value Ipe is continuously judged not to fall outside a second range (S21: NO) and to fall outside a first range (S23: YES) reaches 10 (a first number of times) (S26: YES), a new correction coefficient Kp is computed (S27). In the case where the number of times the representative value Ipe is continuously judged to fall outside the second range (S21: YES) reaches 4 (a second number of times smaller than the first number of times) (S29: YES), a new correction coefficient Kp is computed (S30).
