I rotated my tires about 3 weeks ago. When I last did it I had to reprogram the tpms systerm which was easy as it's all just buttons on the steering wheel.

However this time, no reset. None needed. The I info system didn't say or do anything. But, today I'm driving, and bingo, the tpms low tire pressure orange lights (2?).

I was thinking it was a wheel sensor. All tire pressure right on the usual money. And, I have an indirect system. So I did a reset and it looks cured.

Any ideas? I know I need to recheck the air, and inspect for gum or mud or something on the tires that would cause a drag. Maybe some mud, etc., splashed onto the abs ring and sensor that runs the indirect system.

Any ideas?

Thanks

Does it have the same kind of system as the 10th gen where it just monitors each wheel speed to calculate when one is low? Just do the calibration and forget about it if you already verified tire pressures.

if actual sensors, they have batteries that dies overtime and need to change the whole sensor.
nothing odd there, the car does not know you rotated tires until you tell it

Yes, and no.

Yes, the system is indirect. Thus, I am at the point of having reset and forget it, unless it does it again. But I do want to do a close all around inspection before I take a long trip in 3 weeks.

No, the system last time knew immediately that I had done a tire rotation. After doing the reset it was a ok.

Then on the next tire rotation, it made no complaint. Until a few weeks later, that is, yesterday, when it said low tire pressure. So, yes, I was thinking batteries in the wheel sensors until I realized I had the indrect system which bootlegs off the abs sensors and doesn't have actual pressure sensors in each wheel.

Now I also have a motorcycle. A BMW R1200RT which does have two sensors in the wheels. Which I replaced last year ($540.00) because I was getting new tires and because they were old enough to be ready go fail.

But the Civic is much simpler. But there does seem to be something that would cause a need for a reset if I do a tire rotation, unless the system (indirect, no battery in the tire) is so sensitive as to think one abs ring is ever so slightly different than another that it requires a reset. One time out of two tire rotations.

And then later just driving down the road.

Maybe it's a gremlin in here. I hope not.

A neighbor had issues with TPMS, lite/symbol would come and go.. had a tire shop replace them.. same issue, turns out her spare also has a sensor that was dying battery. Not a Civic, a CRV

Krash, don't crash.

Yes, that was my immediate thought. Bad batteries in the sensors in the tires. But, with a bit more thought I remembered I had an indirect system. One with no sensors in the tires and thus no batteries within the system to go out. Unlike my Jeep and motorcycle which both have sensors in the tires. On my motorcycle, BMW, I replaced the sensors. ($540.00 for two.) I put them in. But they have to be "programmed" with a start program ($10 China made thing) and a computer (GS911 made for BMW motorcycle). But it's nice to have your tire inflation numbers come up on the instrument panel.

On the BMW R1200RT motorcycle the numbers are there all the time. Warning flashers come on if they are too low (or high?) On the Jeep the numbers only come up if there is something out of parameters.

On the LX 2015 Honda Civic the system is known as indirect. That is because it bootlegs off the abs sensor rings on each wheel (no spare ever involved here, like with a direct system).

The rings on each wheel have teeth. A sensor then can tell if one wheel is rotating at a different speed or rate than the others. That indicates to the ABS system (Anti Lock Braking System) that one wheel is slipping (or two, or three). And it adjusts braking to each wheel accordingly to stop a skid. It will also pulse the brakes to keep them from locking up. That's why the rule for ABS brakes on ice or snow is ... SSS. Stomp, stay, steer. Stomp on the brakes and stay on them. You do not need to pump them. The ABS pump does that. Steer, because with the fast pulsing of them you can still steer, you don't have to not steer because your brakes should not lock up.

The Civic also shares that info with the TPMS which then assumes that one tire different speed as others means one tire with low air pressure, or air pressure significantly different than the others. And triggers all the warning lights and flashers and messages.

The Civic has cheap cheap cheap "hub caps", plastic that interfere with putting a gauge or pump onto the tire stem. I finally found a gauge and pump that I can get onto it. (I like alloy wheels and should get some for the Civic, but I do not like the pattern of the '15 Civic EX. I did like the 5 spoke pattern on my 2004 Civic EX Coupe, but they were 4 bolt not 5 bolt like the '15.

The angle type gauge I found is cheap. And grossly inaccurate.

I also did find one tire with a bit low air pressure.

What solved my issue was a simple reset on the TPMS which comes up under "Custom Settings" on the instrument "INFO" and menu screen.

So far, anyway.

The air pump I just got is nice. It is digital, and fits on with the cheap plastic "hub caps" and will pump til it hits the selected air pressure by 1/2 pounds at a time.

As I mentioned above, I did the tire rotation a year ago. And when I did the TPMS system started flashing and beeping and indicating. A simple reset fixed it then, but apparently it didn't like something with the tire rotation.
