Tire air pressure low,Tire3

100%
Causes
- Actual low air pressure in Tire 3 (slow leak, puncture, temperature change)
- Faulty or depleted TPMS sensor battery
- Damaged TPMS sensor or valve stem
- Poor sensor-to-ECU communication (antenna, wiring, module)
- Tire not seated properly on the rim or bead leak
- Recent tire service or rotation without TPMS relearn
Symptoms
- TPMS warning lamp or message indicating low pressure on Tire 3
- Tire 3 appears visibly underinflated
- Possible change in vehicle handling or ride quality
- Warning may clear after inflating but may return
- Relearn/TPMS errors stored in diagnostic tool
What to check
- Visually inspect Tire 3 for obvious punctures, damage, or low sidewall
- Measure Tire 3 pressure with a calibrated gauge and compare to placard value
- Inspect valve stem and core for corrosion or damage
- Use TPMS-capable scan tool to read sensor ID, pressure, temperature, and battery status
- Check for additional TPMS DTCs or communication faults in the vehicle network
- Confirm whether wheels were recently changed/rotated and whether a TPMS relearn was performed
Signal parameters
- Reported tire pressure (kPa or psi) for sensor at wheel position 3
- Sensor battery status or voltage (if available)
- Sensor transmitter ID and diagnostic status
- Sensor-reported temperature (if supported)
- RF signal strength / communication reliability (tool-dependent)
Diagnostic algorithm
- Record the stored TPMS fault codes with a manufacturer-capable scan tool.
- Visually inspect Tire 3 for punctures, embedded objects, or sidelwall damage.
- Measure Tire 3 pressure with a calibrated gauge; compare to recommended pressure on vehicle placard.
- If low, inflate Tire 3 to the specified pressure and monitor for rapid loss; perform soapy-water leak check around bead, valve, and repair area.
- If no obvious leak and pressure stays, clear the TPMS code and perform the manufacturer-recommended drive/relearn procedure or use the scan tool to confirm the sensor reports normal pressure.
- If pressure continues to drop or sensor does not report after inflation, remove the wheel and inspect/replace the valve core and rubber grommet; reseat bead if needed.
- Use the scan tool to read sensor ID and battery/diagnostic data. If sensor battery is low or sensor reports fault, replace the TPMS sensor.
- After sensor replacement or wheel service, perform TPMS relearn/register procedure per Mitsubishi service instructions and confirm the correct sensor ID is assigned to Tire 3.
- If the sensor does not communicate or multiple wheel positions show faults, check TPMS antenna/module wiring and ground; inspect for ECU communication errors.
- Retest by driving or using the tool to confirm the DTC does not return and the TPMS displays correct pressure for Tire 3.
Likely causes
- Puncture (nail/valve core) causing gradual pressure loss
- Corroded or damaged valve/stem allowing leak
- TPMS sensor battery near end of life or sensor failure
- TPMS sensor lost ID after wheel change and not relearned
- Intermittent RF communication due to wiring/antenna/module fault
Fault status
Status
Low tire pressure detected at Tire 3. Check and inflate the tire to the recommended pressure. If the warning persists, inspect for leaks or TPMS sensor faults and perform system diagnostics.
Repair difficulty: Medium
Diagnostic time: 1.0-2.0 hours
