Vw Passat 3B moottorin lämpötila-anturin vika

[Riksu89]

Testasin tuossa aamulla VAG-COMilla vikakoodit 1.8t WV Passatista -97.
Ilmeni vikakoodi P0117 Moottorin jäähdytysnesteen lämpötilapiirin matala sisääntulojännite.

Johtuu anturin hajoamisesta todennäköisesti? Mitä muita vian aiheuttajia voisi olla jota etsiä? Ja missähän hinnoissa nuo anturit mahtavat liikkua?

Tais olla jotain 40e.

16501/P0117 - Engine Coolant Temperature Sensor (G62): Signal too Low
Possible Symptoms

* Difficulties with starting a cold engine.
* Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
* RPM at idle is irregular.
* 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.
* Bad acceleration during warming up.
o Diesel: an indication is extreme long time burning time of the glow indication light.
* Engine Overheating

Possible Causes

* The electrical signal coming from G62 is too low
* Wiring and/or connections faulty (short circuit?)
* Engine Coolant Temperature Sensor (G62) faulty
* Mechanical problems in cooling system

Possible Solutions

* Check wiring and connections
* Check / Replace Engine Coolant Temperature Sensor (G62)
* Check cooling system and correct overheating condition if present

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.
