Causes
- TPMS sensor battery depleted
- Physical damage to Tire 1 sensor or valve stem
- Sensor ID not learned or lost from receiver/BCM memory
- Antenna/receiver fault or poor connection at wheel module
- Wiring or connector fault between receiver/BCM and instrument cluster
- Aftermarket or non‑compatible replacement sensor
Symptoms
- TPMS/warning lamp illuminated on dash
- Tire 1 shows no pressure value or displays “--”/blank for that wheel
- Inconsistent or missing TPMS messages for that wheel during drive
- Possible system shows wrong wheel assignment after rotation
- No sensor ID read when using a TPMS diagnostic tool for Tire 1
What to check
- Retrieve DTCs and freeze frame data with a compatible scan tool
- Check vehicle service history: recent tire change, rotation or aftermarket sensors installed
- Visually inspect Tire 1 valve/sensor for damage, broken stem, corrosion or loose mounting
- Use a TPMS sensor activation/ID reader to attempt to wake and read Tire 1 sensor ID, pressure and battery voltage
- Verify TPMS learn/registration status in the vehicle’s BCM/TPMS module
- Inspect antenna/receiver wiring and connectors and related fuses near the wheel/BCM
Signal parameters
- Typical transmission frequency: 315 MHz or 433 MHz (market dependent)
- TPMS sensor ID (unique hexadecimal identifier)
- Sensor telemetry: pressure (kPa/psi), temperature (°C/°F), battery voltage (~2.0–3.0 V typical), status flags
- Wake-up/tx interval: sensor transmits once every few minutes at rest or continuously while moving; higher rate after activation
- Message integrity: sensor message includes CRC/rolling code and ID that receiver verifies
Diagnostic algorithm
- Connect a full-function scan tool and record DTCs and live TPMS data; note whether only Tire 1 is affected.
- Check service history for recent tire/valve service or sensor replacement.
- Use a TPMS activation tool at the wheel to try to read the sensor ID, battery voltage, pressure and temperature. If the tool reads the sensor, compare the ID to the BCM/TPMS memory.
- If sensor cannot be read: visually inspect the valve/sensor for damage, displacement, corrosion, or loose nut. Demount tire if needed to inspect sensor body.
- Verify antenna/receiver harnesses, connectors and fuses for continuity and secure connections. Repair any damaged wiring or connectors.
- If vehicle supports relearn, perform the TPMS learn/registration procedure to reprogram the sensor ID to Tire 1. Follow manufacturer procedure (service manual) exactly.
- If the sensor still cannot be read or has low battery voltage, replace the Tire 1 sensor with a compatible unit and register the new ID.
- After repair/replacement, clear codes, perform a relearn if required, then road test to ensure the code does not return and the correct pressure is displayed.
- If sensor and wiring are good but the fault persists, check BCM/TPMS module for faults and CAN communications; consult wiring diagrams and test/replace module as required.
Likely causes
- Dead or weak sensor battery on Tire 1 (most common)
- Sensor was replaced or rotated and not re‑learned to the vehicle
- Sensor suffered impact corrosion or was damaged during tire service
- Low or disconnected TPMS antenna/receiver near that wheel (wheel module)
- Faulty BCM/TPMS control unit or intermittent CAN bus communication
Fault status
Status
TPMS sensor for Tire 1 not detected or communication failed — check sensor, wiring/antenna and TPMS module.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
