16706/P0322/000802 - Engine Speed Sensor (G28): No Signal

Possible Symptoms

  • Engine shuts off
  • Engine doesn't start
  • Tachometer / Rev Counter inoperative
  • Glow Plug Indicator Lamp (K29) flashes

Possible Causes

  • Engine Speed Sensor (G28) loose
  • Engine Speed Sensor (G28) faulty

Possible Solutions

  • Check Engine Speed Sensor (G28)

Special Notes

  • The Engine Speed Sensor (G28) is also used as a reference sensor for the crankshaft position.
  • Check the wiring to/from the sensor and engine control module to rule out harness and module damage due to engine oil or coolant from a failed sensor or tensioner. This is an example from a 2012 Tiguan with Coolant in the ECM which resulted in G28 DTCs in addition to intermittent stalling.
