My TPMS module has gone wonky this week. With the drop in temps to the teens around here, the TPMS message came on as normal. Tire pressures are 32 all around both on the system and on , so I ignored the message and it went away after the tires warmed up, as usual.

However, the TPMS system keeps shutting off completely and I see an accompanying message, "TPMS problem", in the MID and on the navi screen. It typically lasts less than five minutes and then the problem goes away.

I have aftermarket wheels with OEM Acura TPMS monitors. However, the entire TPMS system shuts down, so it's not my monitors. Anyone else with this issue? I'm likely to stop by the dealer soon to have it looked at.

To add insult to injury, I bent one of my rims mildly on a pothole. It was either hit the pothole, or swerve into the the next lane left or right, occupied by other cars, and cause an accident. Thankfully, these wheels are cast and so it should be an easy repair. No cracks and the tire is just fine. First time this has happened in my entire lease for this car. The TPMS issue started before that, so I don't think that the pothole injury was to blame.

 

Sounds like a fault in the TPMS. It is losing the connection to the 2 sensors and going into reset mode to re-learn the sensors. That would explain why it goes away a few mins later.

 

Maybe you can check that the connections to the TPMS Control Unit are secure.....

 

I should not type before 1st coffee has kicked in.

 

Thanks, guys. pgeorg, I'll try troubleshooting that way before going to the dealer.

 

There is also one sensor (initiator) in each of the wheel wells, but i don't think they would cause the TPMS unit to go blank. I will post it anyways:

 

32 psi is too low, but since you are not getting a low pressure warning, it has to be something else.

 

Checked for loose connectors and none so far as I can tell. I'm still having the issue, and it is more frequent. I plan to bring it in to the dealer in the next couple weeks to get it sorted out.

 

I finally got the car to the dealer about a week ago.

Beforehand, I swapped the aftermarket wheels for the original wheels, and still the same problem.

The dealer (new service associate) first insisted I put the aftermarket wheels back on to bring the car in. Then after I brought the car in, they insisted on my bringing in the stockers. Good thing I live and work close to the dealer, else this would have been trouble.

It turns out that all they had to do was to run their diagnostic computer and it told them that the driver's front TPMS monitor was faulty. They could not tell me why that message caused the entire system to simply stop responding altogether. They replaced the monitor at my cost (it was on the aftermarket wheel), re-installed my stock wheels, and sent me on my way.

No return of the TPMS issues so far, rolling on the original wheels. I have to repair some scratches on one of my aftermarket wheels, so it'll be a while before they go back on.

I have to find a scanner that reads recent Acura codes; I own two scanners but neither of them reads the most recent Hondacura codes. I could have figured this out myself if I'd thought to do that.

 

A Honda HDS HIM and a windows laptop are needed to read the codes. This tool also has programming abilities. These can be purchased from the orient with hacked software for about $130.

 

Two questions, can I pull the fuse to get rid of the error code on my dashboard until I pick up the parts and can a scan determine if I need all 4 new sensors or just 1. I recently had my tires rotated and within days my sensor light popped on. I have a 2007 TL with 175,000 on the dash.
