Code C0755 2014 GMC Sierra Description
The C0755 diagnostic trouble code (DTC) for a 2014 GMC Sierra refers to the Right Front Low Tire Pressure Sensor. This code indicates that there is a malfunction or issue with the tire pressure sensor located on the right front wheel of the vehicle. Tire pressure sensors are a crucial component of modern vehicles, as they monitor the air pressure in each tire and alert the driver if there is a significant deviation from the recommended pressure.
Common Causes of C0755 2014 GMC Sierra
- Faulty right front tire pressure sensor
- Wiring issues or electrical connections related to the sensor
- Corrosion or damage to the sensor or sensor housing
- Malfunctioning tire pressure monitoring system module
- Low tire pressure or a leak in the right front tire causing the sensor to trigger a warning
Symptoms of C0755 2014 GMC Sierra
- TPMS warning light illuminated on the dashboard
- Inaccurate tire pressure readings displayed on the instrument cluster
- Uneven tire wear on the right front tire
- Decreased fuel efficiency
- Handling or braking issues, especially when turning or braking
How to Fix C0755 2014 GMC Sierra
- Begin by visually inspecting the right front tire pressure sensor and surrounding wiring for any signs of damage, corrosion, or loose connections.
- Use a tire pressure gauge to manually check the tire pressure in the right front tire and inflate it to the recommended pressure if necessary.
- If the sensor itself is faulty, it will need to be replaced with a new one. This may involve removing the tire to access the sensor, depending on the vehicle's design.
- After replacing the sensor, reset the TPMS system to clear the error code and recalibrate the system to ensure accurate readings.
- Test drive the vehicle to verify that the issue has been resolved and that the TPMS warning light no longer illuminates.
Cost to Fix C0755 2014 GMC Sierra
The typical repair costs for addressing a right front low tire pressure sensor issue can vary depending on the specific cause of the problem and the cost of parts and labor. On average, replacing a tire pressure sensor can range from $50 to $200 per sensor, not including the cost of labor. Labor rates at auto repair shops can range from $80 to $150 per hour, with dealership rates potentially higher. It's recommended to consult with a professional mechanic or service center for an accurate cost estimate based on your vehicle's make and model.
Tech Notes for C0755 2014 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.

Frequently Asked Questions about C0755 2014 GMC Sierra Code
1. What does the OBDII code C0755 mean on a 2014 GMC Sierra?
The code C0755 indicates an issue with the right front low tire pressure sensor, typically related to a malfunction or communication failure with the sensor.
2. What are the common symptoms of a C0755 code?
Symptoms include a tire pressure warning light on the dashboard, inaccurate or missing tire pressure readings, and potentially uneven tire wear if the issue is not addressed.
3. What causes the C0755 code to appear?
The code can be triggered by a faulty tire pressure sensor, a dead sensor battery, damaged wiring, or interference with the sensor's signal.
4. Can I drive my 2014 GMC Sierra with a C0755 code?
Yes, you can drive with this code, but it is recommended to address it promptly since it may prevent accurate monitoring of tire pressure, which is crucial for safety and fuel efficiency.
5. How do I fix the C0755 code on my GMC Sierra?
The fix may involve replacing the faulty tire pressure sensor, resetting the TPMS system, or repairing any damaged wiring or connections.
6. How can I reset the TPMS system after fixing the C0755 code?
To reset the TPMS, follow the owner's manual for the relearn procedure, which usually involves using a TPMS tool and adjusting tire pressures in a specific sequence.
7. How much does it cost to replace a tire pressure sensor on a 2014 GMC Sierra?
The replacement cost typically ranges from $50 to $150 per sensor, depending on whether you do it yourself or have a professional perform the repair.
8. What tool is needed to diagnose a C0755 code?
A TPMS scan tool or an advanced OBDII scanner capable of reading tire pressure sensor data is required to diagnose the issue properly.
9. How long do tire pressure sensors typically last?
Tire pressure sensors generally last 5-10 years, depending on usage and battery life. A sensor battery failure is a common reason for this code.
10. Can weather affect the tire pressure sensor and cause the C0755 code?
Yes, extreme temperatures can impact tire pressure and sensor readings, but a persistent C0755 code usually indicates a sensor issue rather than a temporary weather-related fluctuation.
