Suspected Bad TPMS Sensor

[elvisimprsntr]

BACKGROUND

Received a RF leak detected message when the pressure was reading 28 PSI. I checked the tires visually, by touch, and with a magnet and did not find a nail/screw.

I don't have a digital pressure gauge yet (plan to get one that attaches to my pancake comprerssor tomorrow), so I used the readout on the cluster to fill all the tires to exactly 33 PSI, which I confirmed after driving the vehicle a short distance. Now the RF is reading 37 PSI. It seems to be intermittent. When I drive the vehicle the pressure is all over the place.

QUESTIONS

Seems like a bad sensor. I am close to needing an oil change under my service agreement.

1. The question is will they replace the sensor under warranty at QuickLane?
2. Or will I have to schedule an appointment with the dealership?
3. Will they replace it based on my diagnosis if I provide proof?
4. What proof would I need to provide? Pictures, Forscan or other ODB-II scanner data?

Were all the tires cold when you adjusted them all to 33? I had a sensor go bad but it just died and was replaced.

If it is defective, they will replace it under warranty. If it is damaged, they will not. They will replace it for a nominal fee of $197.00. Probably more now. However, if that is the problem, go to Discount tire and they will replace it for about $68.00. This is my experience from a couple of years ago. Prices could be higher.
When I first went to Ford, they didn't even inspect it, they just tried to extort the fee from me. I wouldn't do it and got another service writer to look at it and it was replaced. I never returned to that dealership.

Hi the dealer can do a TPMS reset with a tool they have at Ford , if the sensor is bad they should replace it under warranty. At least they did in my case …

Before I picked up the tire inflater, the false low reading on the cluster caused me to over inflate the tire to 38 psi.

Confirmed bad. What other evidence does the dealer need?

Will they do it at Quicklane or do I have to take it to the strealership service center?

UPDATE: I called Quicklane. They can replace the TPMS sensor under warranty.

Like most manufacturers Ford is not in the business of giving out free parts.
For warranty work Ford has procedures they must perform to diagnose if a part is defective and warrants replacement under warranty.
Typically there is a diagnostic fee involved, if the part is found to be defective, the diagnostic fee will be refunded or waived.

Maybe you'll get lucky and just roll up and say my right front TPMS sensor is bad and needs to be replaced and Quick Lane replaces it under warranty no questions asked and without having to jump through any hoops.

I'm guessing it will not help if I tell them I troubleshoot avionics and jet engine electronics for a living.

Your diagnosis is likely correct.

Unless Quick Lane and Ford feel generous there are boxes that need to be checked that show procedures were followed that prove the TPMS sensor has a defect and requires replacement on Fords dime.

As said, you could get lucky.
You won't know until you buzz on over to Quick Lane.
