I have a 2014 Honda Accord with 85K miles on it. Recently the TPMS light has come on and refuses to go away. The first time I found that the driver's side rear tire had low pressure, so I filled it up and reset the indicator. A couple of days later, it came back on again. This time, the driver's side rear tire was slightly lower than the others (a few psi) but was still in the 30s. I thought maybe I have a slow leak, so I took it in to a tire place and they "fixed" it for 30 bucks. Now it came back on again. Assuming the place didn't fool me, what else could be wrong? Could the sensor be bad?
Thank you for your channel, it's been supremely educational!
Oye.
Aren't all these supposedly convenient and practically worthless electronic devices a lot of fun? I wouldn't have a TPMS on my lawn mower.
Does your Honda’s TPMS system indicate the tire pressure (psi) of all 4 tires on your instrument gauge cluster (or user display)? On some vehicles like my truck (2009) it just says “Low Tire” but doesn’t state which tire or any of the psi numbers - I have to manually check them myself, so the TPMS system is useless . In your case, it could be the battery in the sensor or perhaps the BCM module.
If you are very curious, you would have to hook up a fancier scan tool that can scan the BCM module and see what it is “seeing” with respect to the tire pressures at all 4 wheels. On my truck, I have the TPMS light always on and confirmed all 4 of my sensors work, that they are programmed correctly to communicate with the BCM, that the BCM TPMS system recognizes them (with correct IDs and tire pressures - confirmed against my analog tire gauge measurements). For my truck, if the tire pressures are off by +/- 0.5 psi with respect to each it can set off the TPMS light - so that’s what it was in my case. On my truck it doesn’t display the individual tire sensor readings on the user display in front of me (I have to use my fancy scan tool for that) - so I just live with it.
My Sentra has been blinking for 10 years now. Annoying!
