The control system of air mixing



Sticking in the closed position of the damper mixing air (P2006)
The PCM controls the value of the mass air flow. If the actual flow rate of air flow - of magnitude lower than expected, then, under the following conditions, the PCM believed that air mixing damper system is locked in the closed position:
- Engine speed - 3750 min-1 above;
- Engine coolant temperature - above 63 ?� C;
- The opening angle of the throttle valve - more threshold *.

* The maximum calculated value of the load varies depending on the engine speed

The low level of the input circuit of the solenoid valve control system of mixing air (P2009)
The PCM controls the variable control signal to the solenoid valve system output unit 4T PCM. If the PCM turns off the solenoid valve, but the voltage at the 4T remains low, it said that the chain of the electromagnetic valve control system has a failure of air stirring.

The high level of the input circuit of the solenoid valve control system of mixing air (P2010)
The PCM controls the variable control signal to the solenoid valve system output unit 4T PCM. If the PCM includes a solenoid valve, but the voltage at the 4T remains high, the PCM believes that a chain of the electromagnetic valve control system has a failure of air stirring.
