P0536 - A/C Evaporator Temperature Circuit Range/Performance
P0536 Possible Causes
- Faulty A/C Evaporator Temperature (ACET) Sensor
- A/C Evaporator Temperature Sensor harness is open or shorted
- A/C Evaporator Temperature Sensor circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How do I fix code P0536?Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the P0536 code
Labor: 1.0The cost of diagnosing the P0536 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
- Engine Light ON (or Service Engine Soon Warning Light)
- A/C Inoperative
- A/C Blows Warm
P0536 DescriptionThe A/C Evaporator Temperature (ACET) sensor contains a thermistor which receives a reference voltage from the Powertrain Control Module (PCM). The thermistor then varies the resistance to the reference voltage based on the evaporator discharge air temperature. The resulting voltage is returned to the PCM where it is interpreted as an evaporator discharge air temperature reading.
The PCM maintains evaporator core temperature and prevents icing of the evaporator core, by disengaging the A/C compressor clutch (non-hybrid) or decreasing the electric A/C compressor speed (hybrid) when the evaporator A/C Evaporator Temperature sensor reading falls below acceptable levels, and by engaging the A/C compressor clutch (non-hybrid) or increasing the electric A/C compressor speed (hybrid) when the discharge air temperature rises above acceptable levels.
The A/C Evaporator Temperature sensor is located inside of the heater core and evaporator core housing in the air-stream leaving the evaporator core.
The Diagnostic Trouble Code (DTC) indicates the A/C Evaporator Temperature sensor signal input is not to factory specifications.
