Step-By-Step: How to Reset Your Acura Tire Pressure Light
If your Acura vehicle displays a “check tire pressure” or a low tire pressure warning light follow these steps:
Open the driver side door and find the recommended tire pressure sticker on the door panel.
Adjust or inflate each tire manually to set the tire pressures to the exact pressures your door sticker recommends.
Drive your vehicle above 25 mph for at least 15 minutes.
How Do I Fix My Acura TPMS?
If your Acura tire pressure light does not turn off after following the TPMS reset procedure, here are more options:
First, re-check each tire’s air pressure with a tire pressure gauge to make sure they are all at the exact pressure you set them to previously. If any tire has lost air, inspect the tires for leaks by spraying soapy water on the tread and around the tire beads and valve stems.
Disconnect the negative battery terminal for about a minute to reset the Acura computer system, potentially clearing TPMS faults.
Deflate each tire by around 10 psi, then reinflate to recommended pressure; drive for at least 10 minutes at 25+ mph.
Use a TPMS diagnostic tool to scan all 4 TPMS sensors and identify any that are malfunctioning, which is often the cause of the TPMS light.
What Does it Mean When My Acura Display Says Check TPMS System?
It means one or more tires is low on air pressure or that one or more tire pressure sensors are not working properly.
Can I Drive My Acura With My TPMS Light On?
Driving your Acura with the TPMS (Tire Pressure Monitoring System) light on is not recommended. Driving on underinflated tires can lead to decreased fuel efficiency, poor handling, increased tire wear, and even tire failure. Check and adjust the tire pressures as soon as possible, then reset the TPMS light.
How Does the Acura Tire Pressure Monitoring System Work?
Acura vehicles are equipped with direct TPMS sensors mounted inside each tire’s valve stem. These battery-powered sensors continuously monitor the air pressure and transmit readings to a central receiver. The TPMS system then displays the individual tire pressures on the dash display. If a tire’s pressure drops significantly below recommended levels, the TPMS light illuminates to alert the driver.
What Triggers an Acura Low Tire Pressure Light?
The low tire pressure/TPMS light on your Acura will illuminate if one or more tires drop 25% or more below the recommended cold tire pressure listed in your owner’s manual. Causes can include a slow leak, extreme temperature changes affecting psi, or an issue with a faulty TPMS sensor itself. Check all four tires and the spare with a digital air gauge.
What Does a Flashing Tire Pressure Light Mean?
If your Acura has a flashing tire pressure light it means that one or more tire pressure sensors are no longer communicating with the TPMS receiver or on board computer system. This is known as a TPMS malfunction. TPMS malfunctions usually occur when a sensor battery is low or dead. To diagnose this issue you will need a TPMS diagnostic scan tool.
How Do I Check My Tire Pressure Using the Acura Steering Wheel?
Turn the ignition to the ON position or start the engine.
Press the UP or DOWN arrow on the right side of the steering wheel to scroll through the information display menu until you come to the Tire Pressure Monitoring System display. It will read “Tire Pressure Ok System Function Normal“.
Press the SEL RESET button on the steering wheel.
How Long Do Acura TPMS Sensors Last?
Each Acura tire pressure sensor runs on its own battery which means it has a limited lifespan. Acura tire pressure sensors usually last between 5-10 years or about 100,000 miles. This can vary depending on driving style and the climate you live in.
Can I Disable My Acura Tire Pressure Monitoring System?
No, you cannot permanently disable the Acura tire pressure monitoring system. Removing the tire pressure sensors from each wheel will result in a flashing tire pressure light and then a permanent low tire pressure light on the dash.
Do I Need a TPMS Diagnostic Tool to Fix My Acura TPMS?
Using an OBD2 scanner or dedicated TPMS diagnostic tool can make diagnosing and repairing your Acura’s tire pressure monitoring system much easier. These tools can read sensor IDs, battery status, and pressure data to isolate faulty TPMS sensors. They can also program new tire pressure sensors to the vehicle. Without a tool, Acura TPMS diagnosis relies more on manually checking pressures and observing tire warning light behavior.
