Coolant Temperature Sensor (Cts) Test

NOTE: The following test is for models with separate Idle Speed Control only. For models with integral fuel injection and idle speed control systems, see FUEL INJ - BOSCH LH article in the FUEL SYSTEMS section.

Measure resistance between CTS sensor terminals. Resistance for 4-cylinder engines at 68°F (20°C) should be 2100-2900 ohms and 270-390 ohms at 176°F (80°C). Resistance for V6 engines at 68°F (20°C) should be 8500-11500 ohms and 770-1320 ohms at 176°F (80°C).
