How to fix TPMS error Acura?
A TPMS warning on an Acura usually signals one or more tires are underinflated or a sensor issue. Start by checking all tire pressures and inflating them to the manufacturer’s recommended levels, then reset the system if needed. If the warning persists after proper inflation, you may have a faulty sensor or another component that requires service.
What triggers a TPMS warning on Acura
Understanding common triggers helps you approach the problem methodically. The following are typical causes that can illuminate the TPMS warning light on Acura models:
- One or more tires are underinflated, even if the difference is small.
- Cassi temperatures cause tire pressures to drop, especially after cold starts or winter driving.
- A tire has been rotated, replaced, or repaired and the TPMS has not relearned the new configuration.
- A worn or damaged TPMS sensor battery or sensor itself fails.
- A wheel change or valve stem damage disrupts sensor data transmission.
- Electrical wiring or the TPMS control module has a fault.
If any of these conditions are suspected, proceed with the checks below. Inconsistent readings or repeated warnings often point to sensor or system faults that require service.
How to fix: Step-by-step guide
Use these steps to address a TPMS warning when you drive Acura vehicles. They cover the basics of tire care, system relearns, and when professional help is needed.
- Check all four tires (and the spare, if equipped) and inflate each to the vehicle’s recommended pressure. The correct PSI is usually listed on the driver’s door jamb or in the owner’s manual. Make sure tires are cold for an accurate reading.
- Inspect tires for obvious damage, punctures, or slow leaks. If a tire cannot be repaired safely, replace it and have the TPMS relearn the new setup.
- After inflating to the correct pressures, drive the car at highway speeds (roughly 30–50 mph or 48–80 km/h) for 10–15 minutes to allow the TPMS to relearn the new tire pressures. Some Acura models perform the relearn automatically after proper inflation.
- If the light remains after a normal relearn drive, reset the TPMS using the vehicle’s settings. Typical methods include:
- Infotainment or instrument cluster: Navigate to Settings > Vehicle > TPMS Calibration or TPMS Reset, then confirm the reset. This path can vary by model year, so consult the owner’s manual for the exact submenu.
- Dedicated TPMS reset button: In some models, press and hold a hidden TPMS button (often near the steering wheel, under the dash, or in the glove box) until the TPMS light flashes or the message confirms reset. Then drive to complete relearn.
- If the light still stays on after a reset and a normal relearn drive, there may be a damaged or failing sensor, a faulty receiver, or a systemic fault. A professional inspection is recommended to test sensor batteries, wheel electronics, and the TPMS control module.
Note: TPMS reset procedures vary between Acura models and model years. Always refer to your owner’s manual for the exact reset sequence and relearn requirements, and consider visiting an authorized service center if you encounter repeated warnings.
When to seek professional help
Some TPMS issues require professional tools or service. Seek help if:
- The light persists after inflating all tires to the correct pressures and performing a relearn.
- You suspect a damaged or leaking sensor, a faulty TPMS receiver, or a defective control module.
- You recently rotated or replaced tires and cannot complete a successful relearn.
- You notice uneven tire wear, vibration, or dashboard warnings beyond the TPMS light.
Professional service can diagnose sensor faults, replace faulty sensors, update the TPMS programming, and ensure there are no hidden leaks or calibration errors.
Summary
A TPMS warning on an Acura often stems from underinflated tires or sensor-related issues. Start with a tire pressure check and proper inflation, then drive to allow automatic relearn, and use the vehicle’s TPMS reset feature if needed. If the warning persists, or if you suspect sensor damage or module faults, seek professional service to diagnose and repair the TPMS system.
What is the TPMS error on my Acura?
One of the indicator lights is the tire pressure light, and whenever it pops up, it alerts you that there is an error somewhere in the system. Usually, the most common reason for the TPMS light is a tire that may be under-inflated and needs to be looked at immediately.
How to fix check TPMS system acura?
Turn the key to “On” (one position to the right), but don't start the car. Now hold down the “TPMS Reset” button until the flashing tire pressure light blinks three times. Start the engine and wait 20 minutes. Check your owner's manual if you have trouble finding the reset button.
How much does it cost to repair a TPMS sensor?
The average cost to replace the TPMS Sensor is between $314 and $368.
How to fix TPMS system error?
Often, correcting tire pressure will reset the TPMS.
- Reset the TPMS. Most vehicles allow you to reset the TPMS through the dashboard settings or by pressing a reset button.
- Inspect for Physical Damage. Check each tire and valve stem for visible damage.
- Replace Faulty Sensors.
- Recalibrate the System.
