For drivers of newer Nissan vehicles, the Tire Pressure Monitoring System (TPMS) is a crucial onboard feature designed to ensure optimal tire performance. This system utilizes sensors to continuously monitor the air pressure within the tires, providing real-time alerts if the pressure deviates from the recommended range. In this article, we will explore the workings of the Nissan TPMS, its importance, and what to do when the TPMS light illuminates.
Types of Nissan TPMS
1. Direct Nissan Tire Pressure Monitoring System
This system employs sensors installed inside each tire to directly measure the air pressure. These sensors provide precise and dynamic tire pressure readings, allowing drivers to address issues promptly when the TPMS light activates.
2. Indirect Nissan Tire Pressure Monitoring System
Indirect TPMS, on the other hand, detects pressure changes by monitoring wheel speed, working in conjunction with the car’s Anti-lock Braking System (ABS). It alerts drivers when irregular wheel speed patterns indicate potential low tire pressure conditions.
Importance of Following TPMS Recommendations
Driving with improperly inflated tires can have severe consequences, affecting various aspects of vehicle performance and safety. When the Nissan tire pressure light illuminates, it’s crucial to take action promptly to avoid:
- Changes in vehicle handling characteristics
- Decreased fuel efficiency
- Greater risk of tire puncture
- Greater risk of tire blowout
Regular maintenance, including replacing the TPMS sensor if needed, ensures peace of mind and optimal vehicle performance.
What To Do When the TPMS Light Activates
When the Nissan TPMS light comes on, it is essential to check the tire pressure immediately. If the vehicle doesn’t display the pressure, using a separate tire pressure gauge is recommended. Addressing over or under-inflated tires promptly is crucial to prevent potential complications. Additionally, periodic checks and inspections at a trusted Nissan service center are essential for maintaining tire health.
Frequently Asked Questions
How do I reset the tire pressure monitoring system?
- Inflate tires to recommended PSI.
- Check for leaks.
- If the light persists, press and hold the TPMS reset button or drive the vehicle at 50 mph for 10 minutes.
Why is my tire pressure monitoring system light on?
The TPMS light typically indicates low tire pressure. Adjust air pressure promptly, or a failing TPMS sensor may trigger the light.
How to check the tire pressure monitoring system?
Monitor the dashboard “low pressure” light or use the vehicle’s digital display for TPMS information. Alternatively, use a tire pressure gauge on the valve stem.
TPMS Diagnostic Information – Nissan Altima 2007-2019
In compliance with the TREAD Act since 2007, all US vehicles from 2008 onwards, including the Nissan Altima, feature either direct or indirect TPMS systems. The Altima employs a direct TPMS system with sensors in each wheel, and a TPMS relearn is recommended after tire changes.
- Type of TPMS system: Direct TPMS with sensors in the wheel.
- TPMS frequency: 315MHz
- Relearn procedures: OBD relearn
- TPMS tool required: VT56 or VT46 branded TPMS tool with OBDII module or a shop diagnostic scan tool with TPMS technology.
For Nissan vehicles with push-button start ignition, ensure to switch to the ON mode during the relearn procedure, especially if there is a transfer failure issue.
