The low-tire-pressure light on the Nissan Altima (L32, 2007–2012) is run by a monitoring system that re-checks itself as you drive. There is no reset button and no tool to plug in — correct the pressures and a short drive clears the warning.
How It Works
A sensor in each wheel reports its pressure. When a tire falls well below the recommended cold figure, the warning light comes on. Once you inflate all four tires back to the correct pressure and drive, the system reads the corrected values and turns the light off by itself.
Turning Off the Warning Light
- Read the recommended cold pressures from the placard in the driver’s door opening — check them cold, before driving or after the car has stood a few hours.
- Inflate all four tires (and the spare) to that figure with an accurate gauge.
- Confirm none is high or low — the system compares all four.
- Drive at 16 mph (25 km/h) or more for a few minutes.
- The low-tire-pressure light goes out once the corrected pressures are confirmed.
If the Light Stays On
A warning that flashes for about a minute at every start and then holds steady is a system fault rather than low air — usually a failed sensor or one with a dead battery, which needs equipment to identify. Note too that if a sensor has been replaced the TPMS may need its ID registered before it works again. If the light simply stays on steady, re-check every tire including the spare with a trusted gauge; a slow leak will keep bringing it back.
Frequently Asked Questions
Is there a TPMS reset button? No. The L32 Altima relearns pressures automatically as you drive — there is nothing for the owner to press.
I inflated the tires but the light stayed on. Drive above 16 mph for a few minutes so the sensors are re-read. If it will not clear, one tire may be off or a sensor may be faulty.
What does a flashing-then-steady light mean? That pattern indicates a TPMS fault, not simply low pressure — typically a sensor or its battery, which should be diagnosed.
I fitted new sensors and the light stays on. A replaced sensor may need its ID registered to the car before the system will recognise it.
