Throttle Valve

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2019 Porsche 911, 2018 Porsche 911, 2017 Porsche 911, 2016 Porsche 911, and 2015 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

Necessary after:

Re-programming DME control unit
Replacing DME control unit
Replacing throttle valve

Information

Consequences of Tester adaptation if conditions for automatic adaptation are not met (violated boundary condition):

For a fault entry in the load detection range (P0068 + P1069... P1077), the limits are extended in order to prevent incorrect detections.
This extension is cancelled if an adaptation is performed when the conditions for automatic adaptation are met, or after 15 warm-up cycles at the latest.
(Warm-up cycle = coolant temperature increases by more than 23 °C after start-up and reaches at least 73 ° C)
Following manual throttle valve adaptation when ambient conditions are not met, throttle valve adaptation is carried out again automatically as soon as the ambient conditions are met.
There is NO 30-second waiting time here, but a slightly delayed engine start is possible once.

The ambient conditions for automatic adaptation are as follows:

Engine off and ignition on for > 30 seconds
Accelerator pedal not pressed
Vehicle is stationary
Power supply for throttle valve adjusting unit is OK
Coolant temperature 5 °C... 100 °C
Intake air temperature 5 °C... 30 °C

How?

Ignition on > 30 seconds if preconditions are met.

  Information
  1. Adaptation values are deleted or stored in EEPROM when ignition is switched off after control unit run-on has ended.
  This depends on the run-on period of the engine compartment purge fan.
  
  The run-on period of the engine compartment purge fan AFTER ignition is switched off depends on the engine compartment temperature.
  
  The run-on period is as follows at the following engine compartment temperatures:
  - < 45 °C: approx. 50 seconds
  - 45... 70 °C: approx. 200 seconds
  - > 70 °C: up to 20 minutes
5. 1.5. Switch off ignition.
