what causes the check tire pressure light to stay on in my Genesis G70?

Solution

1. Preparation

• Gather necessary tools: tire pressure gauge, OBD-II scanner, and TPMS reset tool.
• Ensure the vehicle is parked on a level surface and that the tires are cold for accurate pressure readings.
• Disconnect the battery for safety if replacing any TPMS sensors.

2. Tire Inspection

• Sub-step 1: Visually inspect each tire for damage or wear.
• Sub-step 2: Check for any obstructions or punctures that may affect tire pressure.
• Tools Required: None

3. Tire Pressure Adjustment

• Sub-step 1: Use the tire pressure gauge to measure the pressure in each tire.
• Sub-step 2: Inflate or deflate each tire to match the manufacturer's recommended pressure (typically found on a sticker inside the driver’s door).
• Tools Required: Tire pressure gauge, air compressor or tire inflator.

4. TPMS Sensor Replacement (if necessary)

• Sub-step 1: If a faulty TPMS sensor is identified, remove the tire from the wheel to access the sensor.
• Sub-step 2: Replace the sensor with a new one, ensuring it is properly seated.
• Sub-step 3: Reinstall the tire and balance it if necessary.
• Tools Required: Tire removal tools, torque wrench (for lug nuts).

5. System Reset

• Sub-step 1: Reconnect the battery if it was disconnected.
• Sub-step 2: Use the TPMS reset tool or vehicle settings to reset the TPMS.
• Sub-step 3: Drive the vehicle for a short distance to allow the system to recalibrate.
• Tools Required: TPMS reset tool or OBD-II scanner.
