Electric fault tracing General instructions Location of engine signs Measurement of coolant temperature sensor The engines are supplied with two engine signs, of which one is installed on the engine block, as in the il- lustration. The other sign is supplied loose, for installation in a su- itable location close to the engine. 1. Undo the coolant temperature sensor connec- tor. 2. Use the multimeter to measure across the two contact pins on the sensor. The multime- ter should show the following values at: 60° C ......................................................
319 ± 37 Ω 90° C ........................................................128 ± 9 Ω 100° C ......................................................... 97 ± 6 Ω 120° C ......................................................... 57 ± 3 Ω NOTE! The sensor is highly sensitive to temperature changes. It is enough to breathe on it, or hold it in your hand to get an incorrect measurement value. Explanation of engine designation: E.g.
