What is the P0536 Fault code? What does it all mean?
P0536 codes indicate a problem in the temperature sensor circuit of the A/C (air conditioner). The temperature sensor in the evaporator is responsible for sending system voltage data (Vc) to the powertrain control module. This data is used by the PCM to ensure that the air conditioner system works properly. A P0536 fault code is triggered if the PCM experiences excessively high or lower voltage values.
The reverse logic of the air conditioner radiator (also called condenser) and condenser is also used. Condenser converts refrigerant gas into liquid and transfers heat to the atmosphere. Depending on the system design, high pressure fluid can be restricted by an expansion valve or tube. This reduces the refrigerant’s pressure and sends it to an evaporator. A fan blows cold air from the evaporator to the cabin. The coolant pressure drops, and the liquid refrigerant evaporates. It then turns back into gas. It then returns to the compressor, and the cycle continues for as long as there is an air conditioner.
The HVAC (Heating, Ventilation, and Air Conditioning) system must be properly operated by the A/C evaporator temp sensor. To bring the cabin temperature up to the desired levels, the PCM uses the voltage signal received from the sensor. If the PCM detects an abnormal voltage signal from A/C evaporator temp sensor circuit, P0536, P0537 and P0538, the trouble codes P0539 and P0539 are set.
P0536 fault codes can be found on vehicles made by many manufacturers, including Chevrolet, Toyota, Suzuki and BMW.
What is the P0536 Fault Code?
Below are some reasons to set fault code P0536:
- – Temperature sensor defective for the A/C condenser
- Defective expansion valve that causes freezing of the air conditioner radiator
- – A damaged or defective air conditioner radiator
- – Issues with electrical components, such as broken or worn wires and connectors
- Air conditioning systems that are overpriced
- Low refrigerant level
- – Defective air conditioner control panel
What are the symptoms of P0536 Malfunction Code?
You may experience the following symptoms if your vehicle has the code P0536:
- – Illumination at the check engine lights
- – Air conditioner ON/ON flashing
- – Air conditioner doesn’t blow cold air and works irregularly.
- Air conditioning systems may stop working altogether
- – A radiator from the air conditioner is seeping into the vehicle
How to Fix the P0536 Fault Code
To check if the codes return, the scanner should first reset them. The code may not return if it is a periodic malfunction, or was incorrectly set. Visual inspection of all electrical components in the air conditioner system is recommended if the code returns. You should inspect all cables, connectors. harnesses. relays. and fuses for damage. If necessary, replace them. Check the refrigerant level, and if necessary, add more.
After performing these checks, you should inspect the temperature sensor of the evaporator. The valve and air conditioning control panels should also be checked to ensure that the sensor is in good condition. The codes should be reset after replacing any component. After that, restart the vehicle to check if the codes return.
Failure to follow OBD-II fault code diagnostic protocol when repairing P0536 fault codes is the most serious error. To ensure that the correction is accurate, complete, and efficient, it should be followed step-by-step. Excess refrigerant can cause additional damage, even if there is enough.
The following repairs may be able to resolve the P0536 fault code:
- – Replacing the A/C temperature sensor
- Repairing damaged, broken or short-circuited cables
- Repairing or replacing damaged, corroded and burnt connectors
- – Checking the refrigerant and, if necessary topping it up
- – If the expansion valve is not working properly, check it and replace it.
- Repairing an air conditioner radiator that is not working properly
- – Replacing a faulty climate control panel
How serious is the P0536 Fault code?
You can drive a vehicle that has a P0536 fault code. The air conditioner system won’t work, however. Air conditioning may be required for comfort or health, but you never know. You should address this issue immediately if convenience and comfort are important to you.
