P1472 – OBD-II DTC

OBD-II DTC P1472 – A/C Compressor Temperature Sensor Malfunction

DTC P1472 meaning

DTC P1472 refers to a malfunction in the A/C compressor temperature sensor. This diagnostic trouble code indicates that the Engine Control Module (ECM) has detected an issue with the temperature sensor that monitors the A/C compressor’s operating temperature. The sensor plays a crucial role in ensuring the A/C system operates efficiently and prevents overheating.

DTC P1472 symptoms

Common symptoms associated with DTC P1472 may include:

  • Inconsistent or poor A/C performance
  • Increased cabin temperature
  • Compressor not engaging or disengaging unexpectedly
  • Unusual noises from the A/C compressor
  • Illuminated check engine light

DTC P1472 causes

Several factors can lead to the triggering of DTC P1472, including:

  • Faulty A/C compressor temperature sensor
  • Wiring issues, such as damaged or corroded connectors
  • Short circuits or open circuits in the sensor circuit
  • Faulty A/C compressor
  • Issues with the Engine Control Module (ECM)

DTC P1472 seriousness

The seriousness of DTC P1472 can vary. While it may not cause immediate engine damage, it can lead to:

  • Reduced A/C efficiency
  • Increased wear on the A/C compressor
  • Potential overheating of the compressor
  • Overall discomfort for passengers due to inadequate cooling

It is advisable to address this code promptly to avoid further complications.

How to diagnose DTC P1472

To diagnose DTC P1472, follow these steps:

  1. Use an OBD-II scanner to confirm the presence of the P1472 code.
  2. Inspect the A/C compressor temperature sensor and its wiring for visible damage.
  3. Check the sensor’s resistance using a multimeter to ensure it is within specifications.
  4. Test the voltage supply to the sensor while the A/C system is operating.
  5. Examine the A/C compressor for any signs of malfunction.
  6. Clear the code and perform a road test to see if the code reappears.

How to fix DTC P1472 step-by-step instructions

To fix DTC P1472, follow these steps:

  1. Identify and replace the faulty A/C compressor temperature sensor if it is defective.
  2. Repair or replace any damaged wiring or connectors associated with the sensor.
  3. Ensure the A/C compressor is functioning correctly replace it if necessary.
  4. Check the ECM for any software updates or faults that may need addressing.
  5. After repairs, clear the DTC using an OBD-II scanner.
  6. Test the A/C system to ensure proper operation and monitor for any reoccurrence of the code.
