Systems with conventional oxygen sensor. It's coldest where the liquid refrigerant enters the coil from the metering device and warmest where the superheated vapor leaves the coil. (7) to raise the temperature before feeding to the recirculation loop. To get accurate results from your heat load test, you'll have to test the condenser, evaporator and air duct temperatures. The evaporator temperature sensor cannot be adjusted or repaired and must be replaced if inoperative or damaged. 7k at 20 degrees. Because temperature gradients within an air stream are common, in order to fully protect the coil from freeze damage the freeze stat must be able to react to localized cold spots rather than simply the average cross sectional temperature or the temperature at a single measurement point. If everything is working correctly you should not see any faults. The air temperature entering the test section was adjusted by using both a cooling coil and an electric resistance heater installed at the entrance of the flow chamber. ⇒ If the O2S Heater System Status indicator displays NO, ensure that the ignition has been turned OFF for at least 10 hours. Frozen evaporator Run the fan with A/C compressor off, then check evaporator temperature sensor. The coolant temperature sensor, abbreviated as CTS, in your car is an important device that enables the control unit to give alerts if the engine is overheating or if the temperature within the system is rising for some reason. Air mass secondary air injection system. We trust you were able to use some of the tips to better diagnose vehicle electrical issues with temperature and position sensors. A faulty sensor can decrease the life of the engine and reduce the efficiency of fuel consumption. One screw adjusts the set point (works the large spring) and one adjusts the range by tensioning the points that act as the switch contacts. Took our first trip and got almost 30 MPG highway! Solid feel and build. The PCM sources a low current 5 volts on the ACET circuit (this voltage can be measured with the sensor disconnected).
