Code C0775 2017 GMC Sierra Description
The C0775 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a malfunction in the Tire Pressure Monitoring System (TPMS) sensors. The TPMS is a safety feature that monitors the air pressure in each tire and alerts the driver if there is a significant loss of pressure in any of the tires. When the sensors malfunction, it can lead to inaccurate tire pressure readings or a complete failure of the TPMS system.
Common Causes of C0775 2017 GMC Sierra
- Dead or low battery in one or more TPMS sensors
- Physical damage to the sensors, such as corrosion or impact damage
- Signal interference from electronic devices or nearby radio frequencies
- Faulty wiring or connections in the TPMS system
- Communication issues between the sensors and the vehicle's computer system
Symptoms of C0775 2017 GMC Sierra
- TPMS warning light illuminated on the dashboard
- Inaccurate or inconsistent tire pressure readings displayed
- Loss of communication with one or more TPMS sensors
- Erratic behavior of the TPMS system, such as intermittent alerts or false alarms
How to Fix C0775 2017 GMC Sierra
- Use a TPMS tool to diagnose which sensor(s) are malfunctioning
- Replace the faulty TPMS sensor(s) with new ones
- Relearn the TPMS system to sync the new sensor(s) with the vehicle's computer
- Verify proper functionality by checking tire pressure readings and driving the vehicle to ensure the TPMS warning light does not reappear
- Clear the DTC from the vehicle's computer to reset the TPMS system
Cost to Fix C0775 2017 GMC Sierra
The typical repair costs for a TPMS sensor malfunction can range from $50 to $200 per sensor, depending on the make and model of the vehicle and the quality of the sensors used. Labor costs for diagnosis and replacement can add an additional $50 to $100 per hour, with total repair costs varying based on the number of sensors needing replacement and any additional services required. It is recommended to consult with a qualified mechanic or auto repair shop to obtain an accurate cost estimate based on the specific circumstances of the vehicle in question.

Frequently Asked Questions about C0775 2017 GMC Sierra Code
1. What does OBDII code C0775 mean on a 2017 GMC Sierra?
Code C0775 indicates a malfunction in the Tire Pressure Monitoring System (TPMS), specifically related to one or more TPMS sensors.
2. What are the common symptoms of code C0775 on a 2017 GMC Sierra?
Symptoms may include an illuminated TPMS warning light, inaccurate tire pressure readings, or no pressure readings displayed on the dashboard.
3. What causes code C0775 on a 2017 GMC Sierra?
Causes can include a faulty or dead TPMS sensor, interference with the sensor's signal, damaged wiring, or an issue with the TPMS module.
4. Can low tire pressure trigger code C0775 on a GMC Sierra?
No, low tire pressure itself does not trigger this code. However, a malfunctioning TPMS sensor may prevent accurate tire pressure monitoring.
5. How do you diagnose code C0775 on a 2017 GMC Sierra?
Diagnosis involves scanning the vehicle with an OBDII scanner, checking the TPMS sensor battery life, inspecting for physical damage, and testing signal communication.
6. How much does it cost to fix code C0775 on a 2017 GMC Sierra?
The cost depends on the issue, but replacing a single TPMS sensor typically ranges from $50 to $150, including parts and labor.
7. Can I drive with code C0775 on my 2017 GMC Sierra?
Yes, but it is not recommended as the TPMS system may not alert you to low tire pressure, increasing the risk of tire damage or unsafe driving conditions.
8. How do you reset the TPMS after fixing code C0775 on a GMC Sierra?
After repairs, use a TPMS reset tool or follow the vehicle’s relearn procedure, which typically involves setting the correct tire pressures and cycling the ignition.
9. Can a dead TPMS sensor battery cause code C0775 on a GMC Sierra?
Yes, a dead TPMS sensor battery is a common cause of this code, as it prevents the sensor from transmitting data.
10. Do I need to replace all TPMS sensors if one fails on a 2017 GMC Sierra?
Not necessarily. You can replace only the faulty sensor, but if all sensors are the same age, others may fail soon due to similar wear.
