Code C0755:39 Description
The C0755:39 code indicates a Right Front Low Tire Pressure Sensor Internal Malfunction. This means that there is an issue with the sensor responsible for monitoring the tire pressure in the right front wheel of the vehicle. The tire pressure sensor is a crucial component of the vehicle's Tire Pressure Monitoring System (TPMS), which helps ensure optimal tire pressure for safety, performance, and fuel efficiency.
Common Causes of C0755:39
- Sensor internal circuit malfunction
- Sensor battery failure
- Sensor wiring or connection issues
- Sensor physical damage or corrosion
- Electronic control unit (ECU) communication error
Symptoms of C0755:39
- TPMS warning light illuminated on the dashboard
- Inaccurate tire pressure readings displayed on the instrument cluster
- Decreased fuel efficiency
- Poor handling or traction
- Increased risk of a blowout
How to Fix C0755:39
- Begin by confirming the diagnosis of the right front low tire pressure sensor internal malfunction using a diagnostic scanner.
- Locate the right front tire pressure sensor, typically located inside the tire near the valve stem.
- Remove the tire to access the sensor and inspect it for any visible damage or corrosion.
- Replace the faulty sensor with a new one, ensuring proper installation and calibration.
- Clear the diagnostic trouble codes and perform a TPMS reset to ensure the system recognizes the new sensor.
Cost to Fix C0755:39
The typical repair costs for a Right Front Low Tire Pressure Sensor Internal Malfunction can range from $100 to $300, including the cost of the new sensor and labor. However, it is important to note that specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops may charge less. It is recommended to check local rates for a more accurate estimate.
Tech Notes for C0755:39
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.
