I just had tpm recalibrated finally and was informed by Chrysler tech that this is the only model that once the light comes on it must be recalibrated.
He said it will not simply go out when you put air in tire. I thought it does go off after tire has correct pressure.

BTW, there is a recall on the cooling fan module -

 

The tech doesn't know what he's talking about. Mine has come on a few times when the tires were low and always goes out when I put the correct pressure in them without having to have them recalibrated.

 

Get yourself a new tech because he doesn't know what he's talking about. The TPM light most certainly does go out after the tires are re-inflated properly! It can take up to two minutes but it will eventually go out.

 

I agree that the light should go out but mine did not. It had to be recalibrated which I assume lends some credance to the techs explanation. I am just wondering what situation would cause a recalibration to reset the tps light.

Oh my God... Are you kidding me ? This tech should be reported to the dealer and fired... I have two sets of wheels one for the road with TPM sensors and one for the track w/o TMP sensors. I routinely switch them and every time the light extinguishes with the road wheels... No wonder Crossfire owners are dissatisfied with Chrysler service...

 

Your TPM didn't need recalibration. If the light came on and everything was fine, then you had a faulty sensor in one of the tires. Why don't you go and ask the service tech how he would go about recalibrating a TPM and see what response he gives you.

 

The tech did recalibrate the tps!
If I had a faulty sensor then it would not be possible to recalibrate.


Original Symptom:
The light did not go out regardless of what psi I had in tires.
The tech recalibrated and no more light. Basically resetting the tps.

 

There's no way to "recalibrate" the system per se, but what he may have done was reset the system and made it re-learn the ID codes of each of the four wheel sensors. If it's done right, when the TPM light comes on, you should be able to plug a scan tool into the OBD-II port and have the car tell you which tire is low and by how much.

Take a look at your repair order. Did the tech happen to list which code the car was sending?

 

Recalibrate or reset are we splitting hairs? That is what many others call this procedure.
- rebooting the system was required.

Of course, in my case, the tire pressure was ok so that was not the issue.

 

Sorry, Typhoon55, I wasn't trying to be an a-hole. In my mind there's a huge difference between "recalibrate", "reset", and "reboot". In your case it appears that the procedure performed by your service tech was a reprogramming of the TPM.

The Geeky side of me still wants to know what caused the TPM to trip the tire warning light. According to the manual, there are five things that will trigger the light:

1. A failure in the TPM itself.
2. A sensor/transmitter signal jammed.
3. One or more tire sensors not "trained".
4. Low battery in one or more sensors.
5. Low/Critically low tire pressure.


Since we can already eliminate #5, I would be curious to see what exactly it was that triggered the light.

 

I am also curious what evidently causes the tps to require a reset (reprogram) instead of simply putting air in tire.

Of those 5 issues - which would require "only" a reset of the tps?
Maybe #2 or #3 although then inquiring minds want to know what jams a transmitter or causes a sensor to become untrained?

 

I did look at repair order - it stated system was recalibrated. It is evident that the tpm system may occasionally need to be recalibrated as others have also posted. I guess the tech was 1/2 right anyway.
