Code P0533 2016 Honda CR-V Description

The P0533 code on a 2016 Honda CR-V indicates a problem with the A/C pressure sensor circuit registering high voltage. The A/C pressure sensor is responsible for monitoring the pressure levels in the air conditioning system and ensuring proper operation. When the sensor detects high voltage, it can lead to issues with the A/C system's performance, potentially causing the compressor to shut off or the system to malfunction. This can result in poor cooling performance, lack of cold air, or erratic A/C operation. If left unaddressed, the high voltage in the A/C pressure sensor circuit could lead to further damage to the air conditioning system components, resulting in costly repairs.

Frequently Asked Questions about P0533 2016 Honda CR-V Code

1. What does the OBDII code P0533 mean on a 2016 Honda CR-V?

P0533 indicates a high voltage issue in the A/C pressure sensor circuit, which monitors the refrigerant pressure in the air conditioning system.

2. What are the symptoms of code P0533 in a 2016 Honda CR-V?

Common symptoms include the A/C not blowing cold air, the A/C compressor not engaging, and the check engine light being illuminated.

3. What causes the P0533 code in a 2016 Honda CR-V?

Possible causes include a faulty A/C pressure sensor, damaged or corroded wiring, a defective connector, or an overcharged refrigerant system.

4. Can I still drive my 2016 Honda CR-V with the P0533 code?

Yes, you can drive the vehicle, but the A/C system may not function properly, and prolonged use without addressing the issue could lead to further damage.

5. How do you diagnose the P0533 code on a 2016 Honda CR-V?

Diagnosis involves using a scan tool to confirm the code, inspecting the A/C pressure sensor and its wiring for damage, and measuring voltage and resistance in the sensor circuit.

6. How can I fix the P0533 code on my 2016 Honda CR-V?

Repairs may include replacing the A/C pressure sensor, repairing or replacing damaged wiring and connectors, or properly evacuating and recharging the refrigerant system.

7. How much does it cost to repair the P0533 code on a 2016 Honda CR-V?

Repair costs can range from $150 to $400, depending on whether the sensor needs replacement or if wiring repairs are required.

8. Can a low refrigerant level cause the P0533 code in a 2016 Honda CR-V?

No, low refrigerant typically triggers different codes; P0533 is more commonly caused by high voltage, often due to sensor or electrical issues.

9. What tools are needed to fix the P0533 code on a 2016 Honda CR-V?

You may need a multimeter, a scan tool, and A/C system tools like a refrigerant gauge set and leak detector to properly diagnose and repair the issue.

10. Will clearing the P0533 code fix the issue in a 2016 Honda CR-V?

Clearing the code may temporarily turn off the check engine light, but the underlying problem must be addressed to prevent the code from returning.

    • What you’re describing sounds more like a blend door issue than the A/C pressure sensor itself. On the 2016 CR-V, the HVAC system uses blend doors and actuators to control how much hot or cold air comes through each side.

      When one side blows warm and the other side blows cold, common causes are:

      1. Stuck or faulty blend door actuator – The small motor that moves the temperature door may be stuck or failing on one side.
      2. HVAC control recalibration needed – Sometimes disconnecting the battery or a voltage drop causes the actuators to lose their “home” position.
      3. Mechanical obstruction – Something in the ductwork can jam the blend door, though this is less common.

      Here’s what I’d do first:

      • Turn the ignition on, set the temperature from full hot to full cold a few times. Listen for clicking or no movement sounds from under the dash—clicking usually means a stripped actuator gear.
      • If no change, you may need to scan for HVAC codes or perform an actuator recalibration (can often be done with a scan tool or by disconnecting the battery for 10–15 minutes and restarting the car).

      The P0533 code (A/C pressure sensor high voltage) should be addressed separately, but it won’t cause the “one side hot, one side cold” issue. That’s almost always a blend door actuator problem on these CR-Vs.
