TPMs replacement and issues

[merlinq2]

Good morning all,

Just recently replaced my tires and tpms sensors. The sensors worked fine right out of the box. Drove the car for a while and the new TPMS were recognized by the systems within 10 min.

The last few mornings I have noticed that the TPMS light will flash a few times, while at the same time the hazard lights will engage and flash twice and I will hear the chime telling me the hazard lights are on, but i have not engaged the hazard lights.

After driving a few feet, the TPMS light goes off, and I get good readings from all four wheels.

Anyone come across this situation before and have the signal light engage - it engages for three blinks and then stops!

Also, have been looking for information on sloppy shifting transmissions, hard to find any info- I think I need to run the ECU relearn, anyone know if that will clean up the shifting.

Any comments would be greatly appreciated.

Thanks

Hey Merlinq2, Don't know much about the TPMS issue but my transmission was shifting sloppy as well a few weeks ago. After taking the car to the tuner to retune the Transmission he worked the sloppiness right out of the system. If I drive normally it shifts quick but nice. If I tromp it WOT the car shifts so drastically that it's like a kick in the butt in upshifts. Pretty cool.

Where did you get your tires/sensors replaced?
I had a sensor replaced and the system was left in learn mode. Had to go back and it was turned off and no flashing again.

At a tire shop- the system is not it learn mode, the pressures do display properly, just happens to be an issue at start up - after the car has sat for more than 5 or six hours. This morning same thing happened, tpms light flashed three or four times and the hazard lights flashed twice, Drove 20 to 30 feet and all was well. The car is scheduled for a service tomorrow at my nissan dealer and will ask them to check it out.

I got the tpms sensors online and they work perfectly. They cam pre programed for my vin so they were working from the very start, this just started after I exchanged the tires last week.

Which site in particular? Thanks

I will have to check my home email - for some reason I cannot find the link here. Let me see and I will update the post.

I know they saved me about $100 over Infiniti/nissan parts counter in Canada.

That's what I was experiencing. Everything was normal, including the pressure readings, except for the flashing lights at startup.

These are the sensors that I purchased:

I think I got them from alliance automotive- I have a box in the car- will pull them out and have a look at them, they seem to work fines except for the annoying start up light show.

Ok. So they are not oem.

[Wangtang408]

Yep OEM TPMS are blue.

[merlinq2]

No but they were programed for the Nissan code so they work I think I just have a bad sensor and it might just be something I need to live with. I ran the diagnostics and all systems were okay. so I am sure it is nothing to worry about.

Update to my OP- the TPMS sensors are now working, it is a miracle, the temperate dropped and the system i snow working; however, the hazard lights still flash once in every three starts. No one knows what is causing this issue- anyone else heard of this?

Those sensors probably force the BCM into a learn mode when you start the car. The OEM ones are programmed and stay that way unless changes are made to them or the BCM, but these aftermarket ones seem to force their codes into the BCM, which activates the Hazards when it learns new sensors. I think you'll have to to live with it, or have the dealer install OEM ones.

Great answer - thanks for the info- very helpful
