The most common reasons a 2016 Scion iM 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.

How much does it cost to fix a 2016 Scion iM 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.

When a relearn is needed, for any reason, the TPMS warning light will illuminate, and many vehicles will display a message relating to the TPMS system being inoperative or loosing communication. It is important to keep a watchful eye on tire pressures when this system is having issues because there is no warning available for underinflation or overinflation of the tires.

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 steps should I take to diagnose the tire pressure warning light issue on my 2016 Scion iM?

To effectively diagnose the tire pressure warning light issue on your 2016 Scion iM, begin with the simplest and most straightforward approach. Start by checking the tire pressure in all four tires using a reliable tire pressure gauge, ensuring they are inflated to the levels recommended in your owner's manual. This initial step can often resolve the issue if the light was triggered by low pressure. Next, inspect the tires for any visible damage, such as punctures or bulges, which could indicate a more serious problem. If the tires appear to be in good condition, consider resetting the tire pressure monitoring system, as temporary fluctuations can sometimes cause the warning light to activate. Additionally, examine the valve stems for any signs of leaks or damage, as faulty stems can lead to pressure loss. If, after these checks, the warning light remains illuminated, it may be time to consult a mechanic for a comprehensive diagnosis of the tire pressure monitoring system. By following this diagnostic approach, you can systematically address the issue, starting with the simplest solutions before moving on to more complex assessments.

What could be causing the tire pressure warning light to stay on in a 2016 Scion iM?

When the tire pressure warning light remains illuminated in your 2016 Scion iM, it’s essential to understand the common problems that could be causing this issue. The most frequent culprit is low tire pressure, which can easily be checked and adjusted using a tire pressure gauge. If the pressure is adequate but the light persists, the problem may lie with a faulty tire pressure sensor, which may require replacement. Additionally, sensor calibration issues can arise, necessitating a recalibration process to ensure accurate readings. Electrical problems, such as wiring faults or blown fuses, can also trigger the warning light, so a thorough inspection of the vehicle's electrical system is advisable. Lastly, if the tire pressure monitoring system itself is malfunctioning, diagnosing and repairing it may be necessary. By systematically addressing these potential issues, you can effectively troubleshoot the tire pressure warning light and restore your vehicle's safety features.

What immediate steps should be taken if the tire pressure warning light remains on in a 2016 Scion iM?

When the tire pressure warning light remains illuminated in a 2016 Scion iM, it is crucial to act promptly to ensure both safety and vehicle performance. Ignoring this warning can lead to unsafe driving conditions, increased tire wear, and potential blowouts. Start by checking the tire pressure in all four tires with a reliable tire pressure gauge, as maintaining the correct pressure is essential for optimal handling and fuel efficiency. If you find any tires are underinflated, inflate them to the recommended levels found in your vehicle's manual. Additionally, conduct a visual inspection for any signs of damage, such as punctures or cuts, which could compromise tire integrity. After addressing any pressure discrepancies or damage, reset the tire pressure monitoring system using the dashboard controls or following the owner's manual instructions. If the warning light persists despite these efforts, it may indicate a more serious issue with the monitoring system itself, necessitating professional evaluation to prevent further complications. Taking these immediate steps not only enhances your safety on the road but also helps maintain the longevity of your tires.
