Throdlebody and gas peddle out of sink won,t go faster than 30


If you would like help we would need the DTC - diagnostic trouble code .Is their a Reduced Engine Power Mode message showing on the instrument cluster ?
Reduced Engine Power Mode
When the PCM detects a problem with the throttle actuator control (TAC) system the PCM enters one of the following Reduced Engine Power Modes:
• Acceleration Limiting--The control module will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited.
• Limited Throttle Mode--The control module will continue to use the accelerator pedal for throttle control, however the maximum throttle opening is limited.
• Throttle Default Mode--The control module will turn off the throttle actuator.
• Forced Idle Mode--The control module will perform the following actions:
- Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
- Ignore accelerator pedal input.
• Engine Shutdown Mode--The control module will disable fuel and de-energize the throttle actuator.
IF you do not know this your best bet would be to take to a qualified repair shop .
DTC P0506
DTC P0507
The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

Starts and idles, no accelerator response.


Your Denali has Throttle Actuator Control (TAC) System - Electronic throttle control ! Are there any messages on the driver information center ? Reduced engine power ?
Reduced Engine Power Mode When the PCM detects a condition with the TAC system the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
?€¢
Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.


?€¢
Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.


?€¢
Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.


?€¢
Forced idle mode--The control module will perform the following actions:


-
Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.


-
Ignore accelerator pedal input.


?€¢
Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.


You need to have it checked for DTC'S - diagnostic trouble codes , probably a accelerator pedal position (APP) sensor or TPS - throttle position sensor !

1999 vw passat idle air control valve location


The throttle control is not operated with a mechanical wire. But it is a computer controlled system in which the engine ECM controls the engine speed, after getting the data from various sensors. The idle speed adjustment is carried out with special tools and equipment.

99 passat 2.8, vehicle was driven the night


That code is a Throttle Position Malfunction code.

This means one of two things:
1. The throttle body needs replaced
2. After the dead battery, you need to adapt the the throttle body.

The cheap way to do this is to leave the driver's door open, turn the key to the on position, but do not start the car. You will hear the throttle body self-adjust. This may take up to 2 minutes. That should get it close enough. To get it perfect requires a trip to the dealership.

If it does not help, the throttle body might be dead.
