Causes

  • Aging or dead TPMS sensor battery in the sensor at wheel/tire position 3
  • Failed or damaged TPMS sensor (internal fault, water intrusion, mechanical damage)
  • Loose or corroded valve/sensor assembly causing intermittent contact (if serviceable)
  • Aftermarket or incompatible replacement sensor with incorrect frequency or ID
  • Faulty TPMS receiver/module, antenna, or wiring/connectors
  • Interference or loss of RF reception (shielding, wheel cover, heavy corrosion)

Symptoms

  • TPMS warning light or message illuminated on instrument panel
  • No tire pressure reading or an invalid/blank value for tire 3
  • Intermittent TPMS alerts for tire 3
  • Inability to complete TPMS relearn for that wheel position
  • Occasional false low-pressure warnings

What to check

  • Read stored DTCs and freeze frame with a diagnostic scan tool that supports TPMS
  • Use a TPMS service tool to read the transmitter ID and reported battery voltage for tire 3
  • Check live data: confirm sensor ID, battery voltage, signal strength and pressure values for all four wheels
  • Visually inspect the sensor/valve at wheel 3 for damage, corrosion, or loose hardware
  • Verify vehicle battery voltage and ground connections to TPMS module
  • Inspect TPMS receiver/module connectors and wiring for corrosion or looseness

Signal parameters

  • Typical fresh sensor battery voltage: ~2.6–3.3 V (varies by manufacturer)
  • Low condition often reported when transmitter battery falls below ~2.4–2.6 V
  • RF transmission frequency commonly 315 MHz (North America) or 433 MHz (Europe/Asia)
  • Transmission interval: periodic reports while driving (roughly 30–60 seconds) or immediate on wake
  • Expected data fields: sensor ID, pressure, temperature, battery/voltage indicator, RF signal strength

Diagnostic algorithm

  1. Connect a capable scan tool, read and record all TPMS-related DTCs and live data.
  2. Confirm the code is for tire position 3 and note the sensor ID shown in live data.
  3. Use a TPMS activation/read tool to query the sensor at wheel 3. Record reported battery/voltage and RF response.
  4. Visually inspect the wheel/removal area for physical damage, corrosion, or a loose valve core. Replace valve core if leaking.
  5. If the sensor shows low battery or fails to respond, remove the wheel and inspect the sensor body and mounting hardware for damage or corrosion.
  6. If possible, swap the sensor to another wheel position and re-scan. If the fault follows the sensor, replace the sensor.
  7. If the sensor responds fine but the vehicle still shows C1930, check TPMS module power, ground, and antenna connections; test for correct voltage and continuity.
  8. Reprogram or relearn the sensor ID per vehicle procedure after sensor replacement or swap. Clear DTCs and perform a test drive to confirm the code does not return.
  9. If code persists after replacing sensor and verifying the module, consider module replacement or further RF/antenna diagnostics with manufacturer procedures.

Likely causes

  • Sensor battery at end of life (most common)
  • Mechanical damage from tire service or corrosion of sensor body/valve
  • Sensor ID not learned or mismatched after wheel service
  • TPMS module/antenna connector loose or module fault

Fault status

⚠️ Status
TPMS transmitter battery voltage low or poor transmitter signal detected for tire 3. Replace or test the sensor at wheel 3 and verify TPMS receiver/module operation.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-1.5 hours
