Checking Throttle Valve Position Sensor for Eurovan V6-2800cc 28L (AES)
Throttle Position Sensor: Testing and Inspection
Function 04: Basic Setting, Performing
NOTES:
-
Only perform Function 04 "Basic setting" if the Throttle Valve Control Module, Engine Control Module or engine was replaced.
-
Function 04 "Basic setting" (with ignition switched ON) matches the Engine Control Module to the Throttle Valve Control Module.
-
If the Basic setting is interrupted by the Control Module, it is possible that the Throttle body is not positioned on the mechanical stop due to dirt or
contamination build-up such as carbon or an incorrectly adjusted accelerator cable. If this is the case, the malfunction "Basic setting not
performed" will be stored in DTC memory. The next time the ignition is switched ON, Basic setting will automatically be performed again.
