Possible Symptoms

  • Malfunction Indicator Lamp (MIL) active

Possible Causes

  • Wiring/Connector(s) from/to Manifold Pressure/Boost Sensor (G31) faulty
  • Manifold Pressure/Boost Sensor (G31) faulty

Possible Solutions

  • Check Wiring/Connector(s) from/to Manifold Pressure/Boost Sensor (G31)
  • Check Manifold Pressure/Boost Sensor (G31)

Special Notes

  • Results when testing on a fully functional CCTA 2.0L TSFI in a 2012 VW Tiguan Key On, Engine Off:
    • G31 unplugged causing 000568/P0238 - Signal too High:
      • T4eh/1 = ground
      • T4eh/3 = 5.05V (5V supply from ECU)
      • T4eh/4 = 5.73V (Signal return to ECU)
    • G31 plugged in and backprobing
      • T4eh/4 = 1.85V (Signal return to ECU)
