__FORCETOC__
== 16500/P0116/000278 - Engine Coolant Temp. Sensor (G62): Implausible Signal ==

==== Possible Symptoms ====

* Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
** ''Diesel: an indication is extreme long time burning time of the glow indication light.''
* With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
* With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.

==== Possible Causes ====

* Wiring and/or connections faulty
* Engine Coolant Sensor (G62) faulty

==== Possible Solutions ====

* Check wiring and connections
* Replace Engine Coolant Sensor (G62)

==== Special Notes ====

* In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.
* Check if the correct Coolant Fan Control Module/Relay is installed (check part number using parts catalogue)!
