Code C2424 Description

The diagnostic trouble code C2424 indicates an issue with the transmitter 4 battery voltage decrease in the vehicle. This code is typically associated with a problem in the tire pressure monitoring system (TPMS) as transmitter 4 refers to one of the tire pressure sensors. The TPMS is responsible for monitoring the air pressure in the tires and alerting the driver if there is a significant decrease in pressure.

Common Causes of C2424

  1. Battery in transmitter 4 sensor nearing the end of its lifespan.
  2. Wiring issues or electrical faults in the TPMS system.
  3. Physical damage to the transmitter 4 sensor.
  4. Corrosion or moisture affecting the sensor's connection.
  5. Malfunctioning TPMS control module.

Symptoms of C2424

  1. TPMS warning light illuminated on the dashboard.
  2. Inaccurate tire pressure readings displayed on the instrument cluster.
  3. Loss of communication with the TPMS sensors.
  4. Increased fuel consumption due to underinflated tires.
  5. Reduced overall vehicle performance.

How to Fix C2424

  1. Begin by checking the battery voltage of transmitter 4 using a multimeter to determine if it is below the recommended level.
  2. Replace the battery in transmitter 4 with a new one if the voltage is found to be insufficient.
  3. Inspect the wiring and connections in the TPMS system for any signs of damage or corrosion, repairing or replacing as needed.
  4. Test the TPMS system to ensure proper communication with all sensors and accurate tire pressure readings.
  5. If the issue persists, consider replacing the transmitter 4 sensor or the TPMS control module.

Cost to Fix C2424

** The cost of repairing the transmitter 4 battery voltage decrease issue can vary depending on the specific cause and the extent of the repairs needed. On average, the cost for parts such as a new transmitter 4 sensor battery or TPMS control module can range from $50 to $200. Labor costs at auto repair shops typically range from $80 to $150 per hour, with the total repair bill potentially amounting to $150 to $500. It is recommended to consult with a professional mechanic for a more accurate cost estimate based on the specific vehicle and components involved.

Tech Notes for C2424

When the low tire pressure warning light illuminates, immediately check the air pressure of all tires and adjust to the specified pressure. After adjusting air pressure, drive the vehicle at 25 mph (40 km/h) or more to start TPM system re-checking of the tire inflation pressures. Warning light should turn off in a few minutes.

If the warning light is still on after adjusting tire pressure, check for a damaged tire and repair as necessary. If warning light blinks 25 times and then illuminates, and there is not a tire without a tire pressure sensor installed, there is a malfunction in the TPM system. See appropriate manufacturer service information.
