What is the P0535 Fault code? What does it signify?
A P0535 code is an indication that there is a problem with your A/C evaporator temperature sensor. The powertrain control Module (PCM), which monitors the A/C temperature sensor, ensures that the system is working properly. Code P0535 will be activated if the PCM detects a voltage signal from the sensor that is higher than or lower than it should.
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. The expansion valve and orifice tube can restrict high pressure fluid, depending on the design of the system. 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’s pressure drops while the liquid refrigerant is vaporized and becomes gas again. The coolant then returns to its compressor. This cycle will continue as long the air conditioner is on.
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 electrical condition in the circuits or A/C temperature sensor, the P0535 fault code and related codes (P0536. P0537. P0538. P0539.
P0535 fault codes can be found on vehicles made by Nissan, Ford and Suzuki.
What causes the P0535 Fault code?
Below are some reasons to set fault code P0535:
- Defective temperature sensor in A/C evaporator
- – The air conditioner radiator freezes because of a defective expansion valve
- – Damaged or defective air conditioner radiator
- – Electrical components problems such as worn connectors or damaged wires
- Air conditioning systems that are overpriced
- Low refrigerant level
- – Defective air conditioner control panel
What are the symptoms for P0535 fault code?
You may experience the following symptoms if your vehicle has the code P0535:
- – Illumination at the check engine lights
- – Air conditioner ON/ON light flashing
- Air conditioner does not blow cold, it works irregularly or fluctually.
- – Your air conditioner may not work properly
- – The radiator of the air conditioning is leaking into the vehicle
How to Fix the P0535 Fault Code
To check if the codes return, the scanner should first reset them. If the code doesn’t return, it could be a periodic problem or an error. Visual inspection of all electrical components in the air conditioner system is recommended if the code returns. You should inspect the cables, connectors, harnesses as well as relays, relays, and fuses for damage. If necessary, you can replace them. You should also check the level and composition of the refrigerant.
The evaporator temperature sensor must be inspected after these checks. If the sensor isn’t damaged, it should be checked for damage at the valve or air conditioning control panels. The codes should be reset after replacing any component. After that, restart the vehicle to check if the codes return.
Incorrectly following the OBD-II fault codes diagnostic protocol is the biggest error in repairing the P0535 code. For a complete, accurate and efficient correction, the protocol must be followed. Excess refrigerant can cause additional damage, even if there is enough.
Here are some of the possible repairs that could resolve the P0535 fault code:
- – Replacing the A/C temperature sensor
- – Repairing and replacing damaged or broken cables
- Repairing or replacing damaged, corroded and burnt connectors
- – Refrigerant level checking and, if needed, topping it up
- – If the expansion valve is not working properly, check it and replace it.
- – Repairing a damaged air conditioner radiator
- – Replacing a faulty climate control panel
How serious is the P0535 Fault code?
You can drive a vehicle with a fault code P0535. However, the air conditioning will likely not work. Air conditioning may be required for comfort or health, but you never know. This problem must be addressed immediately if you value comfort and convenience as much as I do.
