This summary uses the existing diagnostic information shown in full below.
The car's air conditioning system has a sensor that checks how cold the air is. This code means that the sensor isn't working right, so the car might not know if it's too hot or too cold inside.
The A/C evaporator temperature sensor measures the temperature of the air conditioning evaporator to ensure proper cooling. If the sensor's readings are outside the expected range, this code is triggered.
The P0536 code indicates that the Powertrain Control Module (PCM) has detected a problem with the A/C evaporator temperature sensor's performance. This sensor provides data to the PCM to manage the air conditioning system's operation efficiently. If the sensor's output is not within the expected range, the PCM cannot accurately control the A/C system.
• A/C system not cooling effectively
• A/C system may shut off unexpectedly
• Check Engine Light illuminated
• Faulty A/C evaporator temperature sensor
• Wiring issues or poor electrical connections
• PCM failure
PCM: Powertrain Control Module
A/C: Air Conditioning
• Use an OBD-II scanner to confirm the code.
• Inspect the A/C evaporator temperature sensor and its wiring for damage.
• Test the sensor's resistance and compare it to specifications.
• Replace the faulty A/C evaporator temperature sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regularly inspect A/C system components.
• Ensure proper electrical connections.
• Perform routine maintenance checks.
Sensor Issue
• Have the A/C system checked by a professional.
• Avoid using the A/C until the issue is resolved to prevent further damage.
Check with your vehicle manufacturer for warranty coverage on A/C components.
This code has been commonly reported in vehicles with aging A/C systems or after prolonged use.
Moderate – The A/C system may not function properly, affecting comfort but not safety.
Driving with a malfunctioning A/C system is not a safety concern, but it can lead to discomfort in extreme temperatures.
• Engine running
• A/C system activated
The A/C evaporator temperature sensor is typically located near the evaporator core inside the dashboard.
Q: What happens if I ignore this code?
A: Ignoring this code may result in poor A/C performance and discomfort while driving.
Q: Can I fix this myself?
A: If you have basic automotive knowledge and tools, you may be able to replace the sensor yourself. Otherwise, seek professional help.
