16705/P0321/000801 - Engine Speed Sensor (G28): Implausible Signal
Possible Symptoms
- Engine shuts off
- Engine doesn't start
- Speedometer 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 and correlates with the Camshaft Position Sensor Bank 1 (G40) and Camshaft Position Sensor Bank 2 (G163).
- When found in a VW Golf/Jetta (1J/9M) or Audi A3 (8L) with 1.9l TDI-PD (AXR), check TPI 2007067 which explains issues with electro mechanical interference. A modification to the wiring will fix this problem, extensive details can be found in the named TPI. Even though this TPI was originally released for VW Golf/Jetta (1J/9M), a customer of ours came across the same issue on an Audi A3 (8L).
- When found in a 2004 VW Golf, Jetta, or New Beetle with 1.9l TDI-PD (BEW), check for TSB number 97-05-03 or 97-05-04 calling for a flash update to the ECU and a secondary ground installation. This applies if ECU software version is below 6328; current software version should be 7000 or higher.
