PROBLEM TO BE SOLVED: To readily and reliably detect anomaly of an intake pipe pressure sensor or atmospheric pressure sensor.SOLUTION: The intake pipe pressure sensor 48 detects the pressure of an intake pipe 32 provided in an engine 12. The atmospheric pressure sensor 64 detects atmospheric pressure. An engine ECU 56 obtains a detection result of the intake pipe pressure sensor 48 when the engine 12 is stopped. A local ECU 62 calculates a difference between the detection result of the intake pipe pressure sensor 48 and the detection result of the atmospheric pressure sensor 64 to notify an error when the calculated difference is equal to or higher than a threshold.SELECTED DRAWING: Figure 1 |
