The code of 15 means that the signal voltage of coolant temperature sensor is high --indicating low temperature, whose change regulation of resistance and signal voltages is the same with the code of 14, and its influence range is also the same with the code of 14. Its circuit is shown in Figure 16 and Figure 4. *1 is used to detect whether the fault is actual or caused by interrupted factors, the conditions of generating the fault is: the engine has run for more than 1min; the signal voltage indicates that the temperature of coolant is lower than -37℃, which is opposite to the code of 15 which means warm engine .
