The pressure sensor in the intake manifold
The signal air flow sensor signal is not consistent with the throttle position sensor (P0101) The PCM compares the actual input signal from the pressure sensor in the intake manifold with the expected input from the pressure sensor in the intake manifold (calculated according to the input voltage of the throttle position sensor and engine speed). If the value of the mass flow of the intake air - below 5.0 g / s. for 5 s, and the throttle opening - more than 50% when the engine is running, the PCM determines that the detected value of the mass flow of the intake air is too low. If the value of the mass flow of the intake air - up to 96.5 g / s. for 5 seconds, and the engine speed - below 2,000 min -1, the PCM determines that the detected value of the mass air flow at the inlet is too high.
The high level input circuit of the pressure sensor in the intake manifold (P0102) The PCM monitors the input voltage from the pressure sensor in the intake manifold when the engine is running. If the input voltage at the terminal block 1P PCM - lower than 0.21 V, the PCM determines that the circuit pressure in the intake manifold has a fault.
The high level input circuit of the pressure sensor in the intake manifold (P0103) The PCM monitors the input voltage from the pressure sensor in the intake manifold when the engine is running. If the input voltage to the output unit 1P PCM - above 4.9 V, the PCM determines that the circuit pressure in the intake manifold has a fault.
