I know this is a topic that has been discussed before but can anyone provide any insight into problems I am having with the TPMS indicator light coming on?
I have a 2005 MDX Touring (with no Navi) with over 25K miles and no problems to date except last Saturday evening when I started the MDX, the TPMS light activated and stayed on. I checked the pressure in all 4 tires and all were at or slightly above 32 psi. The next day (Sunday) when I started the MDX, the TPMS light did not say on (usually cuts out about 2 seconds after turning the ignition). Unfortunately Monday morning when I started the MDX the TPMS indicator light stayed on. Finally later on Monday (after work) when I started the MDX, the light did not stay on.
I ready in previous posts about there being a common problem with the 2004 and 2005 MDX model year and the TPMS sensor. Are there any updates (e.g., were there any TSB's published on this subject)?
As the car is still in warranty, I intend to have the dealer diagnose the problem and hopefully confirm (by way of some code) there is a malfunction.
Any feedback would be helpful.
Thanks,

yes, there will be a code for sure
even when it indicates which tire, if you check for codes it will simply have a code for whichever tire is low.
and i do recall an issue with some of the early MDX's, definetly get it checked out, i think they required a new TPMS control module. |

I had the same problem twice in my X. Both times were under the same environmental conditions, eg. the car sat a long while outside in very cold temperatures.
The dealer explained that in very cold temps the battery in the wheel mounted TPMS sensor will loose voltage as it gets cold (we are talking sub 0 F). And because of this cold soaking, at some point the wheel TPMS sensor transmitter is not strong enough to transmit a clear signal to the receiver in each wheel well. Then the TPMS warning light would illuminate. Each time this happened, the warning light would go out after I drove the car a few miles, presumably after the wheel assembly warmed up a bit. I checked, and the tire pressures were always around 32psi during this time.
This all made sense to me, and because it has only happened twice in 3 years and for only a short time, I have accepted it as a design characteristic.
Go figure. I dunno, maybe the dealer was feeding me a line. He did give me the choice of demounting the tires and replacing the sensors. However, I figured that might lead to other problems. It's such a minor occurrence, I'll just live with it. |
