Code C0755 2017 GMC Sierra Description
The C0755 diagnostic trouble code (DTC) for the 2017 GMC Sierra specifically relates to the Right Front Low Tire Pressure Sensor. This code indicates that there is an issue with the tire pressure sensor located on 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 is responsible for monitoring and alerting the driver of any fluctuations in tire pressure.
Common Causes of C0755 2017 GMC Sierra
- Faulty tire pressure sensor
- Low tire pressure due to a leak or puncture
- Sensor interference from electromagnetic or radio frequency signals
- Corrosion or damage to the sensor or its wiring
- Issues with the TPMS module or system
Symptoms of C0755 2017 GMC Sierra
- Tire pressure warning light on the dashboard
- Inaccurate tire pressure readings displayed on the dashboard
- Decreased fuel efficiency
- Poor handling or traction
- Uneven tire wear
How to Fix C0755 2017 GMC Sierra
- Begin by verifying the tire pressure in the right front tire using a manual pressure gauge.
- If the tire pressure is low, inflate the tire to the manufacturer's recommended pressure.
- If the tire pressure is correct, inspect the tire pressure sensor for any visible damage or corrosion.
- Replace the right front tire pressure sensor if it is faulty or damaged.
- Clear the DTC from the vehicle's computer system using a diagnostic tool.
Cost to Fix C0755 2017 GMC Sierra
The typical repair costs for addressing the C0755 code related to the Right Front Low Tire Pressure Sensor on a 2017 GMC Sierra can vary depending on the specific issue and the labor rates in your area. In general, replacing a tire pressure sensor can cost anywhere from $50 to $200 per sensor, including parts and labor. Additional costs may apply if other components of the TPMS system require attention. Keep in mind that diagnostic time and labor rates can vary, so it's advisable to obtain a more accurate estimate from a local auto repair shop.
Tech Notes for C0755 2017 GMC Sierra
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.
