The most common reasons a 2003 INFINITI G35 tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2003 INFINITI G35 tire pressure warning light stays on?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When a tire pressure monitoring sensor fails, the tire pressure monitoring system control module will recognize a loss in communication and turn on the warning lamp which indicates the failure. This is most often the case. However, the tire pressure monitoring sensor may also fail by reporting incorrect tire pressures. This could cause a flat tire to go unrecognized, or a properly inflated tire to signal a low or high tire pressure warning.

Wheels offer very few symptoms, but these symptoms should never be ignored. Visible cracks on the wheels may appear, especially after hitting a large bump, Most often, this will also be accompanied by loss of air from the tire on that wheel. Also, vibration in the steering wheel is very common when the tire is out of balance, and improper wheel nuts or bolts can cause creaking and popping noises to develop. Again, there are very few symptoms, but they should not be ignored.

The only symptoms requiring diagnosis for the tire pressure monitoring system warning lamp is if the warning lamp has illuminated while the tires have correct air pressure, or if the air pressure for the tires is out of specification and the warning lamp is off. This is because the overwhelming majority of cases where the TPMS lamp illuminates is due to the change in ambient temperature.

What are the initial steps to diagnose the tire pressure warning light issue on a 2003 INFINITI G35?

To effectively diagnose the tire pressure warning light issue on your 2003 INFINITI G35, begin with a thorough check of the tire pressure in all four tires using a reliable tire pressure gauge. It's crucial to ensure that the pressure aligns with the manufacturer's specifications, which can typically be found in the owner's manual or on a label located inside the driver's side door jamb. Next, conduct a visual inspection of each tire for any visible damage, such as punctures, cuts, or bulges, and look for any foreign objects that may be embedded in the tread. If everything appears normal, consider resetting the tire pressure monitoring system, as this can sometimes resolve temporary issues that trigger the warning light. Additionally, don't overlook the spare tire; check its pressure as well, since it may be integrated into the monitoring system. By following these initial steps, you can effectively narrow down the cause of the warning light and determine if further professional assistance is needed.

What could cause the tire pressure warning light to stay on in a 2003 INFINITI G35?

When the tire pressure warning light stays on in a 2003 INFINITI G35, it is crucial to identify the underlying issues that may be causing this alert. The most common reason is low tire pressure, which can be easily checked and adjusted to meet the manufacturer's recommended levels. If the tire pressure is adequate, the next step is to consider the possibility of a faulty tire pressure sensor, which may need replacement to ensure accurate readings. Additionally, the internal batteries of these sensors can wear out over time, leading to the need for a battery replacement. Another factor to consider is whether the tire pressure monitoring system requires recalibration, a task that can typically be performed by following the instructions in the vehicle's manual. Lastly, an electrical fault within the monitoring system or its wiring could also trigger the warning light, necessitating a thorough diagnosis and repair. By methodically addressing these common problems, you can effectively troubleshoot and resolve the tire pressure warning light issue in your INFINITI G35.

What immediate steps should be taken to address the tire pressure warning light that remains on in a 2003 INFINITI G35?

Neglecting the tire pressure warning light in your 2003 INFINITI G35 can lead to serious safety risks and potential damage to your vehicle. It's crucial to act promptly when this warning appears, as driving on underinflated or damaged tires can compromise handling, increase tire wear, and even lead to blowouts. Start by checking the tire pressure in all four tires with a reliable gauge, ensuring they meet the manufacturer's specifications. If you find any tires are underinflated, use an air compressor to bring them up to the correct pressure. Additionally, inspect each tire for visible damage, such as punctures or bulges, which could necessitate repair or replacement. After adjusting the tire pressure, resetting the tire pressure monitoring system is often required to clear the warning light. If the light persists despite these efforts, it’s essential to consult a qualified mechanic to diagnose any underlying issues with the monitoring system. Addressing these concerns promptly not only enhances your vehicle's performance but also ensures your safety on the road.
