1. Display System coolant temperature includes built in the instrument panel meter and placed on the engine sensor information. By car provided several sensors CTS, however, in the display system using only one of them.  |  |
2. If the engine is cold, uniquely captures the meter overheating, check the wiring on the circuit between the dashboard and the sensor unit for signs of a short circuit to ground.
3. If the meter does not work at all (arrow remains fixed even after the 10-minute warm-up of the engine) at the fuse, switch off the engine and disconnect the wiring from the sensor temperature. With the jumper wire jumper the sensor wire to ground. For a short time, turn on the ignition without starting the engine. If the indicator needle is deflected to the end of the scale, replace the sensor.
4. To test the sensor disconnect the electrical wiring and connect an ohmmeter between the pin at the top of the sensor and the ground power unit. When the engine is warm slightly (about 60 ?� C) the ohmmeter should be about 70 ÷ 90 Ohm models until 1998 Vol. and 170 ÷ 200 ohm models 1999 Vol. After the engine has warmed up to a temperature of 100 ?� C, the instrument reading must fall to (21 ÷ 24) / (47 ÷ 53) ohms, respectively, otherwise replace the temperature sensor. |
