Tire ID reception fail,Tire3

Causes

  • Dead or weak battery in the Tire 3 sensor
  • Faulty or damaged Tire 3 sensor (mechanical or electronic failure)
  • Sensor not programmed/registered to vehicle or ID mismatch
  • RF interference or poor radio reception to receiver antenna
  • Faulty TPMS receiver/module or antenna wiring/connectors
  • Recent wheel/tire change, sensor swapped or mounted incorrectly

Symptoms

  • TPMS warning lamp or message illuminated on dash
  • No pressure/temperature data displayed for one wheel (Tire 3)
  • Inconsistent or missing tire pressure readings after vehicle start
  • Service message instructing to check Tire 3 sensor

What to check

  • Read all stored TPMS/BCM codes with a scan tool and confirm C1931 is present
  • Retrieve and compare stored sensor IDs with IDs being received by the vehicle (using a TPMS diagnostic tool)
  • Attempt to activate Tire 3 sensor with a TPMS tool and read its telemetry (pressure, temp, battery voltage, sensor ID)
  • Visually inspect wheel/tire for aftermarket sensor, damage, or incorrect mounting
  • Inspect TPMS receiver/antenna connectors and wiring for corrosion, damage or poor connections
  • Check for other related DTCs that may indicate module or wiring faults

Signal parameters

  • Sensor RF frequency: typically 315 MHz or 433 MHz (region dependent)
  • Sensor ID: 8–16 hex characters (tool dependent)
  • Battery voltage: typically ~2.6–3.3 V for healthy sensor (varies by sensor)
  • Tire pressure: typical operating range 100–500 kPa (15–75 psi) depending on vehicle
  • Temperature: -40°C to +125°C (sensor operating range)
  • Wakeup/telemetry interval: 30–300 seconds when stationary; more frequent when moving

Diagnostic algorithm

  1. Connect a scan tool and confirm C1931 and any other TPMS codes. Record stored sensor IDs from the vehicle.
  2. Use a TPMS activation/diagnostic tool at Tire 3 to attempt to read the sensor ID, pressure, temperature and battery voltage.
  3. If the sensor responds with valid telemetry and ID matches stored ID, check receiver/antenna wiring and module; if no response, proceed.
  4. If the sensor battery voltage is low or no telemetry, replace the Tire 3 sensor and program/learn the new sensor ID per manufacturer procedure.
  5. If a new sensor is installed or sensor IDs changed, perform the required TPMS relearn/registration procedure (manual or drive-based) until the system recognizes the sensor.
  6. Inspect TPMS receiver antenna and wiring for damage, corrosion or poor connections. Repair or replace as needed.
  7. If receiver/antenna and sensors are good but problem persists, check BCM/TPMS module software updates and consider module replacement if confirmed faulty.
  8. Clear codes, perform a drive cycle or relearn, and verify the TPMS warning no longer appears and the Tire 3 sensor reports correctly.

Likely causes

  • Sensor battery at end of life (most common)
  • Sensor physically damaged during tire service or by impact
  • Sensor ID not learned after sensor replacement or wheel rotation
  • Receiver antenna loose, corroded or disconnected

Fault status

⚠️ Status
TPMS fault: Failed to receive ID from Tire 3 sensor. Check sensor battery/ID, RF reception, antenna and TPMS module.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2.0 hours
