6. 1. _ _ 9 - 41 SIGNALING SYSTEM ELEC – + ELEC – + Coolant temperature sensor Remove the coolant temperature sensor from the cylinder head. Connect the pocket tester (Ω × 100) to the coolant temperature sensor 1 as shown. Immerse the coolant temperature sensor in a container filled with coolant 2. TE: ke sure the coolant temperature sensor minals do not get wet. Place a thermometer 3 in the coolant. Slowly heat the coolant, and then let it cool to the specified temperature indicated in the table. Measure the coolant temperature sensor resistance. • Does the coolant temperature sensor operate properly?
YES NO Coolant temperature sensor resistance 290 ~ 354 Ω at 80 °C (176 °F) WARNING andle the coolant temperature sensor ith special care. ever subject the coolant temperature ensor to strong shocks. If the coolant emperature sensor is dropped, replace t. Coolant temperature sensor 18 Nm (1.8 m · kg, 13 ft · lb) T.R.
