DTC Description
Note: The symptom byte can not be displayed on a scan tool.
DTC P02E0 (01): The control circuit adjusting the air inlet valve (Short to Battery)
DTC P02E0 (02): Control circuit control valve air intake (short to ground)
DTC P02E0 (04): Control circuit control valve air inlet (open circuit)
<DIV closure_uid_8mdy7s="1541">
DTC P02E0 (54): The control circuit adjusting the air inlet valve (high temperature)
DTC P02E1 (11): The efficiency of the control circuit adjusting the air inlet valve (above the maximum threshold)
DTC P02E1 (12): The efficiency of the control circuit adjusting the air inlet valve (below the minimum threshold)

Circuit / System Description
To maintain a high degree of exhaust gas recirculation system is used, the throttle (TAC) It increases the pressure difference between the output and intake, providing the right amount of mixing of the exhaust gases with intake air.
<DIV closure_uid_8mdy7s="1545">The ECM passes the desired angular position of the throttle on the throttle control module (TAC) as a signal to the PWM. TAC module activates the DC motor that controls the throttle position based on the input signal with pulse-width modulation. Set the throttle to the desired position is provided by the internal feedback circuit with a potentiometer, which does not require external control of power by the ECM.
