Dear Beforemountains,

Hope you're well and that New Year has started nicely. To assess an engine coolant temperature sensor - Volvo #1346030 / Bosch #0 280 130 032) - what matters is resistance (Ohms [Ω]).

The Volvo Pocket data booklet - Cars (700, 850, 900; 1991-1996, p. 34) shows the following:
-10⁰C / 14⁰F = Ω 8200 - 10600
+20⁰C / 68⁰F = Ω 2200 - 2800
+80⁰C / 186⁰F = Ω 250 - 400.

These values are for cars using Rex/Regina fuel/engine management. The same sensor is used in cars with Rex/Regina or Bosch fuel/engine management.

Hope this helps.

Yours faithfully,

Spook
