Our automotive experts have put together the following information about the P0536 diagnostic trouble code. We've provided the common symptoms that occur when this code is set along with the frequent repairs that address the issues related to the P0536 code.

OBD II Fault Code

  • OBD II P0536

    OBD-II Code A/C may not operate is defined as a A/C Evaporator Temperature Sensor Circuit Range/Performance

    The A/C Evaporator Temperature Sensor is used verify proper operation of the A/C system and to prevent the evaporator from getting too cold and freezing up. The engine computer (PCM) looks to see a temperature change when the A/C Compressor is activated. When the engine control module (PCM) does not see a change in temperature with the A/C compressor turned on, the PCM will set code P0536. On hybrid vehicles, this sensor may be controlled and used by the Hybrid Powertrain Control Module.
