Code U1228 Description
The U1228 diagnostic trouble code (DTC) indicates that there is invalid or missing data for tires in the vehicle's system. This code typically points to a communication issue between the tire pressure monitoring system (TPMS) sensors and the vehicle's onboard computer. The TPMS is responsible for monitoring the air pressure in each tire and alerting the driver if there is a significant change in pressure. When the system detects an issue with the data it receives from the sensors, it will trigger the U1228 code.
Common Causes of U1228
- Faulty TPMS sensors
- Corroded or damaged wiring connecting the sensors to the onboard computer
- Software issues with the vehicle's computer system
- Malfunctioning onboard computer
- Low battery power in the TPMS sensors
Symptoms of U1228
- TPMS warning light illuminated on the dashboard
- Inaccurate or inconsistent tire pressure readings on the display
- Loss of communication with TPMS sensors
- Increased tire wear on one or more tires
- Decreased fuel efficiency due to improper tire pressure
How to Fix U1228
- Use a diagnostic scan tool to retrieve the specific details of the U1228 code and determine which tire or sensor is causing the issue.
- Inspect the TPMS sensors and wiring for any signs of damage or corrosion. Replace any faulty sensors or repair damaged wiring.
- Reset the TPMS system and relearn the tire pressure sensor IDs to ensure proper communication.
- Update the vehicle's software if necessary to address any software-related issues.
- Test drive the vehicle to verify that the U1228 code has been resolved and that the TPMS is functioning correctly.
Cost to Fix U1228
The cost of repairing the U1228 code can vary depending on the specific cause of the issue. On average, the repair costs for this type of problem can range from $100 to $300, including parts and labor. However, it's important to note that the actual cost can be higher if multiple sensors need to be replaced or if there are underlying electrical issues that require additional diagnostics and repairs. As mentioned earlier, labor rates at auto repair shops can vary, so it's recommended to obtain quotes from local shops to get a more accurate estimate.
