Water Temperate Gauge Problem?

[jick.cejoco]

I have a 2002 Isuzu Trooper 4jx1 engine.

1) my problem is ung temperate gauge ayaw gumagana - nasa C lang plagi kahit pinatakbo ko na? pinalitan ko ng water temp sensor, ganun parin. what do you think is the problem? pls help

you probably replaced the coolant temperature sensor not the coolant temperature sending unit.
