Most ACDelco TPMS sensors cannot have their batteries replaced. They use a potting compound for protection against vibration and shock, which ensures durability. Attempting to replace the battery often damages the sensor. These sensors are designed for long-term use without battery replacement.
Begin by safely removing the tire from the vehicle. Next, locate the TPMS sensor, which is usually attached to the valve stem. Use the screwdriver to gently pry open the sensor casing without damaging it. Carefully remove the old battery and dispose of it properly. Insert the new CR2032 battery, ensuring it is oriented correctly.
After replacing the battery, reassemble the sensor and securely attach the casing. Reinstall the tire and ensure everything is fastened properly. Before driving, check that the TPMS is functioning.
Once you’ve replaced the battery, it’s essential to reprogram the sensor for precise operation. This involves ensuring the system recognizes the new battery. In the following section, we will guide you through the reprogramming process for ACDelco TPMS sensors.
Can You Replace the Battery in an ACDelco TPMS?
Yes, you can replace the battery in an ACDelco Tire Pressure Monitoring System (TPMS) sensor.
Replacing the battery is important for maintaining accurate tire pressure readings and ensuring the proper functionality of the TPMS. The ACDelco TPMS sensors typically have a limited battery life, generally lasting around 5 to 10 years. When the battery dies, the sensor will not transmit data, causing warning lights to illuminate on the dashboard. As a result, timely battery replacement can prevent potential tire damage and promote safe driving practices.
What Symptoms Indicate That the Battery in an ACDelco TPMS Needs Replacing?
The symptoms that indicate the battery in an ACDelco Tire Pressure Monitoring System (TPMS) needs replacing include low battery warning alerts, decreased sensor responsiveness, and fluctuating tire pressure readings.
- Low battery warning alerts
- Decreased sensor responsiveness
- Fluctuating tire pressure readings
These symptoms can vary based on individual experiences and external conditions, leading to different perspectives on when a battery replacement is necessary. Some experts suggest that factors like tire pressure variations caused by weather changes can also mimic battery issues. Others argue that sensor age plays a critical role in performance degradation.
-
Low Battery Warning Alerts:
Low battery warning alerts in an ACDelco TPMS signal that the sensor battery is running out of power. When the battery’s voltage decreases, the TPMS communicates this issue to the vehicle’s display. For example, some vehicles will illuminate the warning light on the dashboard, indicating the need for attention. The manufacturer suggests that these warnings may appear when the battery voltage drops below a specified threshold. -
Decreased Sensor Responsiveness:
Decreased sensor responsiveness means the TPMS does not react quickly or accurately when monitoring tire pressure. This delay or failure to report can lead to serious safety issues on the road. Studies indicate that responsive sensors are crucial for real-time monitoring. Failure to replace the battery may result in undetected tire pressure issues, which can cause tire blowouts or decreased fuel efficiency. -
Fluctuating Tire Pressure Readings:
Fluctuating tire pressure readings indicate that a sensor may not provide consistent data due to battery issues. Inconsistent readings may confuse the driver and lead to inappropriate responses. Research conducted by tire safety organizations shows that tire pressure must be maintained at optimal levels for safe driving conditions. Erratic sensor data can mislead the driver about the actual tire pressure, emphasizing the need to address battery failure promptly.
Thus, when these symptoms are present, it is advisable to examine the battery in the ACDelco TPMS for replacement.

Which Battery Type Should You Use for an ACDelco TPMS?
The recommended battery type for an ACDelco Tire Pressure Monitoring System (TPMS) is a CR2032 coin cell battery.
- Battery Type:
– CR2032
– CR2025
– CR2016
Various perspectives exist when it comes to battery options for ACDelco TPMS. Some users prefer the CR2032 for its longevity, while others might opt for the thinner CR2025 to save space. Conflicting opinions arise about using cheaper generic batteries versus brand-name options.
-
CR2032:
Using the CR2032 type battery is highly recommended for ACDelco TPMS. The CR2032 is a 3V lithium coin cell battery known for its long shelf life, typically exceeding 10 years. This battery is widely available and commonly used in automotive applications, ensuring compatibility and reliability. Many TPMS systems use CR2032 as the standard due to its balance of size and capacity. -
CR2025:
The CR2025 is another option but is only 2.5mm thick compared to the 3.2mm thickness of the CR2032. This battery can work in some situations but may provide shorter life expectancy. It is less common in TPMS applications and may not fit securely in devices specifically designed for CR2032 batteries. -
CR2016:
The CR2016 battery is even thinner at 1.6mm. It is less frequently used in TPMS applications. While it may fit some devices designed for thicker batteries, it often lacks the necessary capacity for reliable performance in systems that demand more energy, such as TPMS.
In summary, the CR2032 is generally the most suitable and reliable choice for an ACDelco TPMS, while the CR2025 and CR2016 may serve as alternative, albeit less optimal, options. User experiences may vary based on their specific models and preferences.
