Code C0765 2015 GMC Sierra Description
The C0765 diagnostic trouble code (DTC) for a 2015 GMC Sierra specifically refers to the Right Rear Low Tire Pressure Sensor. This code indicates that there is a malfunction or issue with the tire pressure sensor located on the right rear wheel of the vehicle. The tire pressure sensor is a crucial component of the vehicle's tire pressure monitoring system (TPMS), which is designed to alert the driver when tire pressure is low or if there is a significant change in pressure.
Common Causes of C0765 2015 GMC Sierra
- Faulty tire pressure sensor
- Damaged sensor wiring or connectors
- Low battery voltage in the sensor
- Corrosion or debris affecting sensor functionality
- Tire pressure sensor not properly programmed or calibrated
Symptoms of C0765 2015 GMC Sierra
- Illuminated TPMS warning light on the dashboard
- Inaccurate or fluctuating tire pressure readings
- Loss of tire pressure data for the right rear tire
- Increased tire wear on the right rear tire
- Decreased fuel efficiency
How to Fix C0765 2015 GMC Sierra
- Begin by visually inspecting the right rear tire pressure sensor for any visible damage or corrosion.
- Check the sensor wiring and connectors for any signs of wear, damage, or loose connections.
- Test the battery voltage of the sensor to ensure it is within the proper range.
- If necessary, replace the right rear tire pressure sensor with a new, compatible unit.
- Program and calibrate the new sensor to ensure accurate tire pressure readings.
Cost to Fix C0765 2015 GMC Sierra
The typical repair costs for addressing a Right Rear Low Tire Pressure Sensor issue can vary depending on the specific cause of the problem and the cost of parts and labor. In general, replacing a tire pressure sensor can range from $50 to $200 per sensor, with additional costs for programming and calibration. Labor rates at auto repair shops can vary, but typically range from $80 to $150 per hour. It's advisable to check with local shops for a more accurate estimate based on your location and vehicle specifics.
Tech Notes for C0765 2015 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 C0765 2015 GMC Sierra Code
1. What does the OBDII code C0765 mean on a 2015 GMC Sierra?
C0765 indicates an issue with the right rear tire pressure sensor, specifically that it is reporting low or no pressure.
2. What are the common symptoms of code C0765?
Symptoms include a tire pressure warning light on the dashboard, inaccurate tire pressure readings, or no reading from the right rear tire.
3. What causes the C0765 code to appear?
Common causes include a faulty tire pressure sensor, low tire pressure, damaged wiring, or interference with the sensor's signal.
4. How do I fix the C0765 code on my 2015 GMC Sierra?
First, check and inflate the right rear tire to the recommended pressure. If the issue persists, inspect or replace the tire pressure sensor and check the wiring for damage.
5. Can I drive my 2015 GMC Sierra with the C0765 code?
Yes, but it’s important to manually check the tire pressure to avoid driving with an underinflated tire, which can cause safety issues or damage to the tire.
6. How do I reset the tire pressure monitoring system (TPMS) after fixing C0765?
Use the vehicle's TPMS reset procedure, typically found in the owner’s manual, which may involve using a TPMS tool or following a specific sequence of actions with the ignition and tire pressures.
7. How much does it cost to replace a tire pressure sensor on a 2015 GMC Sierra?
The cost to replace a tire pressure sensor typically ranges from $50 to $150 per sensor, including parts and labor.
8. Can a dead battery in the tire pressure sensor cause the C0765 code?
Yes, a dead or weak sensor battery can cause the TPMS to malfunction and trigger the C0765 code.
9. How do I know if the right rear tire pressure sensor is faulty?
If the right rear tire pressure does not display or consistently shows an error despite proper inflation, the sensor may be faulty and require replacement.
10. Can weather conditions affect the appearance of the C0765 code?
Yes, extreme cold weather can cause tire pressure to drop, potentially triggering the code. Inflate the tire to the correct pressure and see if the issue resolves.
