- Low or High Tire Pressure: If the tires are under- or over-inflated, the TPMS may trigger a warning. Make sure to check your tire pressure regularly, especially with temperature changes.
- Sensor Battery Life: The TPMS sensors run on small batteries, which typically last 5-10 years. A failing or dead battery in one of the sensors can trigger a warning.
- Corrosion or Damage: TPMS sensors can get damaged or corroded due to exposure to salt, water, or extreme weather.
- System Malfunctions or Software Issues: Occasionally, a software glitch might cause TPMS warnings, which can often be resolved with a reset.
Steps to Troubleshoot and Fix the TPMS on a Jeep Compass
1. Check and Adjust Tire Pressure
- Locate the Recommended Pressure: Check the recommended PSI for your Jeep Compass on the driver’s door sticker.
- Check All Tires: Use a reliable tire pressure gauge to measure each tire’s PSI. Adjust each to the recommended level, then drive for about 10-15 minutes to give the system time to recalibrate.
- Spare Tire: If your Compass has a full-size spare with a TPMS sensor, ensure it’s also at the correct pressure.
2. Resetting the TPMS
If the warning light stays on after adjusting pressure, follow these steps to reset the TPMS:
- Turn the Key to the “On” Position: Without starting the engine, turn the key to “On” for a few seconds, then off. Repeat this two to three times.
- Drive Above 15 MPH: Many systems recalibrate themselves if you drive above this speed for a few minutes.
- Manual Reset (If Available): On some models, use the Compass’s screen interface to access the TPMS reset option.
3. Inspecting TPMS Sensors
- Use a TPMS Scan Tool: A mechanic or tire shop can use this tool to identify which sensor may be faulty or out of battery.
- Replace Faulty Sensors: If a sensor has a dead battery or is malfunctioning, it will need to be replaced. Some shops can handle sensor replacement and recalibration.
4. Software Update or Dealer Diagnostics
If you’ve followed the above steps and the light remains on, it’s possible that your Compass may need a software update or a diagnostic check. Jeep service departments often have the latest updates to resolve software glitches that may impact the TPMS.
Pro Tips for TPMS Maintenance
- Seasonal Checks: Sudden changes in temperature can affect tire pressure and trigger the TPMS light. Check your tire pressure at least every few months.
- Routine Inspections: When getting your tires rotated or balanced, ask the technician to inspect the TPMS sensors for any visible damage or corrosion.
