Code C0755 Description

The C0755 code indicates a problem with the right front low tire pressure sensor in the vehicle's tire pressure monitoring system (TPMS). The TPMS is responsible for monitoring the air pressure in each tire and alerting the driver if there is a significant drop in pressure, which could affect the vehicle's handling, fuel efficiency, and overall safety.

C0755 Code - Right Front Low Tire Pressure Sensor

Common Causes of C0755

  1. Faulty right front low tire pressure sensor
  2. Damaged wiring connecting the sensor to the TPMS module
  3. Corrosion or debris obstructing the sensor's signal
  4. Malfunctioning TPMS module
  5. Low battery voltage affecting sensor communication

Symptoms of C0755

  1. TPMS warning light illuminated on the dashboard
  2. Inconsistent or incorrect tire pressure readings displayed on the dashboard
  3. Loss of communication with the right front tire sensor
  4. Increased fuel consumption due to underinflated tire(s)
  5. Uneven tire wear due to improper tire pressure monitoring

How to Fix C0755

  1. Use a TPMS tool to diagnose the specific issue with the right front low tire pressure sensor.
  2. Inspect the sensor, wiring, and TPMS module for any visible damage or corrosion.
  3. Replace the faulty sensor if necessary, ensuring proper installation and calibration.
  4. Clear the diagnostic trouble codes from the vehicle's system.
  5. Test drive the vehicle to confirm that the TPMS warning light is no longer illuminated and that the sensor is functioning correctly.

Cost to Fix C0755

The typical repair costs for addressing the C0755 code related to the right front low tire pressure sensor can range from $100 to $300, including the cost of the sensor itself, labor, and any additional parts or diagnostic fees. However, the final cost may vary based on the vehicle make and model, the location of the repair shop, and the specific underlying issue causing the code. It is recommended to consult with a qualified mechanic or dealership for a more accurate estimate tailored to your vehicle's needs.

Tech Notes for C0755

A sensor may have been damaged due to a previous wheel/tire service or flat tire event.
Some aftermarket wheel valve stem holes are located further from the wheel rim than the original equipment wheels. When using the tire pressure monitor special tool to activate a sensor, ensure the tool is placed along the tire sidewall and no further than 15 cm (6 in) from the sensor and the antenna is aiming upward.
Occasionally sensors can become mislocated due to previous tire rotations where the sensor learn procedure was not performed. Always learn the sensors to ensure the DTC set is for that actual physical corner of the vehicle.
A sensor with low battery condition will set a sensor DTC but will not illuminate the low tire pressure indicator or display a message on the driver information center if equipped. The sensor battery condition can be verified in the scan tool BCM data list. If a sensor's low battery condition is indicated on the scan tool, the sensor will need to be replaced.
