The P0535 OBD-II code refers to an issue with the A/C evaporator temperature sensor circuit. This diagnostic trouble code (DTC) indicates that the engine control module (PCM) has detected a malfunction in the A/C evaporator temperature sensor circuit.
What Does the P0535 Code Mean?
The P0535 code signifies that the PCM is not receiving the expected temperature readings from the A/C evaporator temperature sensor when the A/C compressor is activated. This could result in the A/C system not functioning properly, which may lead to inadequate cooling inside the vehicle.
What Causes the P0535 Code?
Several factors can contribute to the setting of the P0535 code, including:
- A/C evaporator temperature sensor failure
- Powertrain Control Module (PCM) failure
- Wiring issues in the sensor circuit
What Are the Symptoms of the P0535 Code?
Common symptoms associated with the P0535 code include:
- Inoperative A/C system
- Poor cooling performance from the A/C
- Potential issues with defrosting windows
How Serious Is the P0535 Code?
The P0535 code is classified as a moderate severity issue. While it may not pose an immediate threat to vehicle safety or functionality, it is advisable to have it diagnosed and repaired in a timely manner. Ignoring this code could lead to more serious A/C system problems down the line.
How to Diagnose the P0535 Code
Diagnosing the P0535 code involves several steps, including:
- Using an OBD-II scanner to confirm the presence of the P0535 code.
- Inspecting the A/C evaporator temperature sensor and its wiring for any visible damage.
- Testing the sensor with a multimeter to ensure it is functioning correctly.
- Checking the PCM for any malfunction or error codes that may indicate broader issues.
Common Repairs for the P0535 Code
Repairs for the P0535 code may include:
- Replacing the A/C evaporator temperature sensor if found defective.
- Repairing or replacing damaged wiring or connectors.
- Reprogramming or replacing the PCM if necessary.
How Much Does It Cost to Fix the P0535 Code?
The cost to fix the P0535 code can vary widely depending on the underlying issue. Typical repair costs may range from $100 to $400, including parts and labor. If the PCM needs reprogramming or replacement, costs could be higher.
Can I Fix the P0535 Code Myself?
If you have basic automotive knowledge and the right tools, you may be able to diagnose and repair the P0535 code yourself. However, due to the complexity of A/C systems and potential PCM issues, it is often advisable to consult with a professional mechanic for accurate diagnosis and repair.
