The TPMS light on your Cavalier isn’t a suggestion. When it stays on after a tire rotation or new sensor install, the system has lost track of which sensor is at which corner. The fix is a relearn procedure. Here’s how to do it without guessing.
What TPMS Relearn Actually Does
Relearn pairs each sensor’s unique ID to a physical location: left front, right front, right rear, left rear. The system uses a 433MHz signal from each sensor. Done right, the next time you adjust tire pressure or hit a pothole, the dash knows exactly which wheel is low.
On most Cavalier-compatible GM systems, there isn’t one universal procedure. So start with the simplest method and move up only if the light stays on.
Three Ways to Relearn a Cavalier TPMS
1. Auto Relearn (No Tools)
Some newer GM TPMS modules will automatically sort the sensors after a short drive. This is common on vehicles with the “auto relearn” feature. Try this first if you just rotated tires and don’t have a TPMS tool.
- Set all four tire pressures to the values on the driver’s door sticker.
- Drive the vehicle above 15 mph for 10 to 20 minutes on a straight road.
- Stop, turn the ignition off, then back on.
- Check the TPMS light. If it’s out, you’re done.
If the light still blinks or stays solid, your Cavalier doesn’t support auto relearn, or the sensors are too old to trigger it. Move on to a stationary method.
2. OBD Relearn (Using a TPMS Scan Tool)
This is the most reliable way to relearn a Cavalier. You’ll need a bidirectional TPMS tool that can send the learn command through the OBD port. Common options are the Autel TS508, TS401, or similar.
- Connect the TPMS tool to the OBD port under the dash.
- Turn the ignition to ON (engine off).
- Select “TPMS Relearn” or “Sensor Learn” in the tool menu.
- Follow the tool’s prompts to put the module into learn mode.
- When the horn beeps or the headlights flash, go to the left front tire.
- Use the tool’s trigger function to activate the sensor. Hold the tool next to the valve
