No start - P0116 code V70-XC70 1999

posted by  someone claiming to be Peter on  Fri Nov 3 04:21 CST 2006 [RELATED]

The car started this morning with a Check Engine light, and the fan running. So, apparently a bad coolant temperature sensor CAN cause a no start. At least in this case,it failed with the engine warm.

The resistance range for that sesnor is 5740 ohms at zero degrees C to 184 ohms at 100 degrees C. When I put an ohm meter across it, it started 1.6M ohms and kept climbing. (1.6M ohms is 16,000 ohms, right?) So my guess is that the mixture was so overrich that the car flooded (or else the computer is programmed not to start at that range).

The most annoying thing is that I replaced that sensor 11 months ago, with a Volvo original part.
