Don't miss
- The engine control unit calculates the angle sender voltage values as a percentage in relation to 5 volts and displays this percentage figure. (5 volt supply voltage equates to 100 %).
- The figure shown in display zone 3 must always be approximately double the figure shown in display zone 4.

📋 Procedure
- Connect fault reader V.A.G 1551 or vehicle system tester V.A.G 1552 or vehicle diagnosis and service information system VAS 5052 and select the engine control unit with "“Address word”" 01. The ignition must be switched on for this purpose: 01.
- Press keys 0 and 8 for function "“Read measured value block”" and confirm entry with Q key.
- Press keys 06 and 2 for "“Display group number 62”" and confirm entry with Q key.
- Check reading from accelerator pedal position sender G79 at idling speed stop in display zone 3. Specification: 6…96 %.
- Check reading from accelerator pedal position sender 2G185 at idling speed stop in display zone 4. Specification: 3…48 %. [Note: The engine control unit calculates the angle sender voltage values as a percentage in relation to 5 volts and displays this percentage figure. (5 volt supply voltage equates to 100 %).]
- Press the accelerator pedal slowly to full throttle position and note the percentage figure in display zones 3 and 4 when doing this: [Note: The figure shown in display zone 3 must always be approximately double the figure shown in display zone 4.]
- Press the → key.
- Press keys 0 and 6 for function "“End output”" and confirm entry with Q key.
- Switch off ignition.

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
