What is the Honda Tire Pressure Monitoring System (TPMS)?
The air pressure inside your tires is what supports the weight of your vehicle. Tire pressure is the air pressure specification, measured in pounds per square inch (PSI), that should be used for a specific tire type and size.
Select Honda models, depending on the model year and trim level, are equipped with a Tire Pressure Monitoring System (TPMS). The TPMS monitors the tire pressure in your vehicle either directly by way of pressure sensors in each tire or indirectly by monitoring the speed at which each wheel turns. (See your vehicle’s owner’s manual to determine which type of system is equipped with your vehicle.)
The system has two indicators: low tire pressure and malfunction. The low tire pressure indicator informs the driver that a tire has low pressure and, if applicable to your model, the tire affected and its current PSI. The malfunction indicator is a notification that the TPMS is not working properly.
Low tire pressure indicator:
The TPMS is equipped with a low tire pressure indicator that alerts the driver under several conditions. Some of the conditions that may cause the TPMS warning light to come on include but are not limited to:
Tire(s) underinflated or overinflated Flat tire Low ambient temperature Altitude change Driving with snow chains Mismatched tires Compact spare tire installed Unbalanced load
If your low tire pressure indicator comes on at any point, we recommend checking your tires right away for debris and/or under–or over-inflation. Adjust them as soon as possible to the tire pressure listed on the label in your doorjamb (or the applicable tire pressure for your tires if you have installed tires of a different size than what is listed). Please do this when you are parked in a safe location and the tires are cold.
TPMS malfunction indicator:
When the system detects something is not working properly, this malfunction indicator will illuminate. It is likely that once this indicator comes on, the system will not be able to monitor the tire pressure. If your malfunction indicator light is on, we recommend taking the vehicle to your Honda dealer as soon as possible.
If the tire pressure is adjusted in any of the tires or the tires are rotated or replaced, indirect TPMS systems will need to be calibrated. Calibration instructions for applicable models can be located in your owner’s guide or owner’s manual. If you have adjusted the tire pressure and the indicator light has not gone off after a substantial distance of driving and there are no calibration instructions in your owner’s manual, you should visit your local Honda dealer for assistance. Your Honda dealer can also assist you if either indicator light keeps coming on or is staying on.
You should not ignore a TPMS indicator light. Driving on tires not properly inflated could cause the tire to overheat, which can lead to tire failure and a crash. It can also reduce fuel efficiency and the useful life of your tires. Taking care of your tires contributes to positive handling, ride, comfort, and safety performance. Please take the TPMS seriously, and address any issues right away to help optimize the performance of your vehicle.
Though the TPMS is there to conveniently assist you in monitoring your tires, please do not rely on it for tire maintenance. Honda recommends that drivers inspect all tires monthly and make adjustments as needed to the tire pressure noted on the label in your doorjamb (or the applicable tire pressure for your tires if you have installed tires of a different size than what is listed). It is the driver’s responsibility to ensure that the tires are operating at the recommended tire pressure at all times.
