C0755 Tire Pressure Monitor (TPM) system sensor not transmitting

The OBD2 code C0755 indicates that the Tire Pressure Monitor (TPM) system sensor is not transmitting data, which means the vehicle's system is unable to receive signals from one or more tire pressure sensors

Definition

The OBD2 code C0755 indicates that the Tire Pressure Monitor (TPM) system sensor is not transmitting data, which means the vehicle's system is unable to receive signals from one or more tire pressure sensors

Common causes

  • Dead or low battery in the tire pressure sensor
  • Faulty tire pressure sensor
  • Damaged or corroded sensor wiring or connectors
  • Incorrect tire pressure
  • Sensor not properly installed or seated
  • Interference from other electronic devices
  • Malfunctioning vehicle's TPM system or module
  • Tire rotation without resetting the TPM system

Common misdiagnoses

  • Faulty Tire Pressure Monitoring System (TPMS) sensor
  • Dead or weak battery in the TPMS sensor
  • Incorrect tire pressure
  • Faulty TPMS receiver/module
  • Wiring issues or damaged connectors
  • Software or calibration issues in the TPMS
  • Tire rotation or replacement not reset in the system
  • Interference from aftermarket electronics or devices

Troubleshooting steps

  1. 1. Check the Tire Pressure

    Verify Tire Pressure: Ensure that all tires are inflated to the manufacturer's recommended pressure. Low tire pressure can sometimes trigger TPM issues

  2. 2. Inspect the TPM Sensors

    Visual Inspection: Check the physical condition of the tire pressure sensors. Look for any signs of damage, corrosion, or loose connections

  3. 3. Sensor Battery

    If the sensors are battery-operated (most are), check if the batteries are dead or weak. Some sensors have a limited lifespan

  4. 4. Check for Interference

    Electronic Interference: Ensure that there are no electronic devices or aftermarket accessories that could be interfering with the TPM signal

  5. 5. Scan for Additional Codes

    Use a Diagnostic Scanner: Check for any additional trouble codes that may provide more context or indicate related issues

  6. 6. Reset the TPM System

    TPM Reset: Some vehicles require a reset of the TPM system after tire rotation, sensor replacement, or battery change. Refer to the vehicle’s manual for the specific reset procedure

  7. 7. Check the Vehicle’s TPM Module

    Module Functionality: Inspect the TPM control module for any faults. This may involve checking connections, wiring, and ensuring the module is functioning correctly

  8. 8. Software Updates

    Check if there are any software updates available for the vehicle’s TPM system

  9. 9. Test the Sensors

    Sensor Activation: Use a TPM tool to activate and read the sensors. This can help determine if the sensors are transmitting correctly

  10. 10. Replace Faulty Sensors

    If a sensor is found to be non-functional, it may need to be replaced

  11. 11. Check Wiring and Connections

    Inspect Wiring: Look for damaged or frayed wires leading to the TPM sensors and module. Repair or replace any damaged wiring

  12. 12. Connector Integrity

    Ensure that all connectors are secure and free from corrosion

  13. 13. Consult the Vehicle Manual

    Manufacturer Guidelines: Refer to the vehicle’s service manual for specific troubleshooting steps and specifications related to the TPM system

  14. 14. Professional Diagnosis

    Seek Professional Help: If the issue persists after performing the above steps, consider taking the vehicle to a qualified technician or dealership for a more in-depth diagnosis. By following these steps, you should be able to identify and potentially resolve the issue related to the C0755 code. Always ensure safety when working on vehicles, especially when dealing with tires and pressure systems
