“Volkswagen Jetta 2002 Model.Epc on the dashboard.The car started perfectly but doesn’t respond to acceleration with the following codes P1223,P2128,P0413.What can be done Sir.”

How much do i need to pay before putting me through ?.
Possible causes
Harness or connectors (The TP sensor 2 circuit is open or shorted.)
Electric throttle control actuator (TP sensor 2)
When is the code detected?
An excessively low voltage from the TP sensor 2 is sent to ECM.
P1223 Description
Electric Throttle Control Actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
P2128 Throttle/Pedal Position Sensor/Switch ‘E’ Circuit High
P0413 VOLKSWAGEN Secondary Air Injection System Switching Valve ‘A’ Circuit Open
Possible causes
– Faulty Air Pump inoperative
– Air bypass solenoid harness is open or shorted
– Air bypass solenoid circuit poor electrical connection
When is the code detected?
The DTC P0413 is detected the the AIR vacuum control solenoid circuit not operating as desired by the PCM.
P0413 VOLKSWAGEN Description
An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.
