Causes

  • TPMS sensor not registered / relearn not completed after tire change
  • Dead or weak TPMS sensor battery
  • Destroyed, missing or physically damaged sensor (valve assembly)
  • Aftermarket or incorrect-frequency sensor incompatible with vehicle
  • Faulty TPMS receiver/antenna or module
  • Intermittent or open wiring / poor connector at TPMS module

Symptoms

  • TPMS/TPMS warning lamp illuminated on dash
  • No/blank or missing tire pressure data for one or more wheels in the instrument cluster or scan tool
  • Repeated TPMS relearn failures
  • Intermittent TPMS warnings or false low-pressure alerts after service

What to check

  • Read stored freeze-frame and current codes with a compatible Mitsubishi diagnostic scanner
  • Confirm vehicle history: recent tire change, rotation, or sensor replacement
  • Visually inspect each valve/sensor for damage, corrosion, or missing sensors
  • Measure actual tire pressures and compare to instrument/scan tool readings
  • Use a dedicated TPMS activation tool to interrogate each sensor: read sensor ID, pressure, temperature, battery voltage, and RF signal
  • Check for related communication codes on CAN bus (e.g., U-codes) and verify TPMS module power and ground

Signal parameters

  • TPMS sensor ID code (unique hex/ID)
  • Tire pressure (kPa or PSI) reported by sensor
  • Tire temperature (°C/°F) from sensor (if supported)
  • Sensor battery voltage or status (if available)
  • RF signal strength / RSSI from sensor to receiver
  • Number of learned sensors recorded in TPMS module

Diagnostic algorithm

  1. Connect a professional Mitsubishi-capable scan tool and read all TPMS/ABS/body codes; record freeze-frame data
  2. Verify tires and wheels: confirm present sensors and check for physical damage or aftermarket sensors
  3. Use a TPMS activation/diagnostic tool at each wheel to read the sensor ID, pressure, temperature and battery level; note any wheels with no response
  4. If a sensor responds but ID is not registered, attempt the factory TPMS relearn/registration procedure exactly as specified in the service manual
  5. If a sensor does not respond, replace the sensor or its valve assembly and re-attempt registration
  6. If registration fails with a known-good sensor, inspect and test the TPMS receiver/antenna and related wiring for power, ground, and continuity
  7. Check module communication on the CAN bus; repair any network issues or related module faults
  8. If hardware and wiring are good, check for available ECU/TPMS module software updates from Mitsubishi and apply if recommended
  9. After repairs or registration, clear codes, recheck for stored faults, and perform a road test to confirm stable TPMS operation

Likely causes

  • TPMS sensors were not re-learned after tire rotation or replacement
  • One or more sensor batteries are depleted (end of life)
  • Incorrect replacement sensors (wrong frequency/ID format) were installed
  • TPMS receiver/antenna or module fault preventing sensor ID reception

Fault status

⚠️ Status
TPMS Tire ID code not registered — one or more sensor IDs missing or not learned by the TPMS module.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
