Causes
- TPMS sensor battery weak or dead in Tire 1 transmitter
- Damaged or corroded TPMS sensor (physical impact or water intrusion)
- Sensor not programmed or wrong sensor ID for the vehicle
- Poor RF reception (antenna/receiver fault or wiring/connectors issue)
- Interference from aftermarket electronics or metal shielding
- Receiver/module software glitch or intermittent communication fault
Symptoms
- TPMS warning lamp on instrument cluster for low/invalid sensor
- No TPMS pressure/battery readout for one wheel (Tire 1) on a scan tool
- Intermittent or missing sensor transmission while driving
- TPMS warning persists after setting correct tire pressures
- Difficulty performing TPMS relearn or sensor registration
What to check
- Confirm exact code and freeze frame with a capable scan tool (verify Tire 1 target)
- Visually inspect tire pressures and wheel/sensor area for damage or corrosion
- Use a TPMS diagnostic tool to read the Tire 1 sensor ID, battery voltage, frequency and signal strength
- Verify if the code follows the wheel: swap wheel positions and see if code/ID moves
- Inspect wiring and connectors to the TPMS receiver/ECU for corrosion, looseness, or damage
- Check for recent wheel/sensor replacements and whether relearn/programming was performed
Signal parameters
- Typical TPMS transmitter battery nominal voltage: ~3.0 V (new); battery considered weak below ~2.5 V (varies by sensor)
- Transmission frequency commonly 315 MHz (NA) or 433 MHz (EU/Asia) depending on market and vehicle
- Transmission interval: wakes on wheel motion; may transmit every ~30–90 seconds when driving (intervals vary)
- Sensor ID (unique identifier) embedded in RF message; receiver must match ID to tire position
- Signal strength can be reduced by metal obstruction, wheel design, or damaged antenna
Diagnostic algorithm
- Scan vehicle to confirm C1910 and capture TPMS sensor data (ID, battery, pressure, frequency).
- Verify actual tire pressures and visually inspect the wheel and valve stem/sensor area for damage or corrosion.
- Use a TPMS activator/diagnostic tool at each wheel to verify the sensor for Tire 1 transmits and to read battery voltage and ID.
- If the sensor does not respond or shows low battery, remove wheel and inspect/replace the sensor. If battery low, replace sensor (most sensors sealed; replace entire sensor assembly).
- If sensor appears functional, perform a swap test: move the suspected Tire 1 wheel to another position and see if the code/ID follows the wheel. This distinguishes sensor vs. receiver/ECU issue.
- Inspect and test TPMS receiver module and antenna wiring for continuity, corrosion, and proper power/ground. Repair any wiring faults.
- Reprogram/relearn the sensor IDs per manufacturer procedure after any sensor replacement or wheel rotation.
- Clear the code and perform a test drive to confirm the warning does not return. If code returns, escalate to checking receiver/ECU software and communications or consult factory service information.
Likely causes
- End-of-life battery in the Tire 1 TPMS transmitter (most common)
- Failed TPMS sensor (mechanical damage or internal electronics failure)
- Sensor ID mismatch after wheel or sensor replacement without relearn
- Faulty TPMS receiver or antenna leading to no/bad battery reading
- Loose or corroded connector to TPMS receiver module
Fault status
Status
TPMS transmitter battery voltage abnormal or no valid battery-level signal received for Tire 1 (possible dead/low battery, damaged sensor, ID or receiver fault).
Repair difficulty: Medium
Diagnostic time: 30-120 minutes
