Code P0538, A/C not working properly?

A P0538 code means the PCM voltage from the evaporator temperature sensor that are outside of specification. The car doesn't go into EV mode will need to be its own question please post your new question here, you must be logged in.

Here is the location of the evaporator temp sensor so you can change it out, The ACET sensor monitors the evaporator air discharge temperature. The ACET sensor is a thermistor device in which resistance changes with temperature. The ACET sensor is used to more accurately control A/C clutch cycling, improve defrost/demist performance and reduce A/C clutch cycling. The electrical resistance of a thermistor decreases as the temperature increases, and the resistance increases as the temperature decreases. The PCM sources a low current 5 volts on the ACET circuit. With SIG RTN also connected to the ACET sensor, the varying resistance affects the voltage drop across the sensor terminals. As the A/C evaporator air temperature changes, the varying resistance of the ACET sensor changes the voltage the PCM detects.

You may need to remove the evaporator core which requires vacuum down and rechrage of the system. Check out this video to show you how and the diagrams in the images below to show you how to do the job.
