Santa Claus lives! Continuing with the saga, when I operated the Transit Connect today there was no TPMS indicator light on .... as it has been for over a month. It never came on during driving. I started and turned off the vehicle several times with the same result, the TPMS light never came on. Whatever caused the light to come on has disappeared. The indicator light is still functional as it shows up briefly in the startup sequence. Although completely confused, I am pleased.

As I have now gone several weeks with a lighted TPMS warning on the dash, every week seems to have dulled the impact of having the light on. I am thinking after another month or two, it may not bother me at all. Perhaps when time comes to replace tires, I may revisit this issue again (possibly taking it to a Ford dealer) but for now I will live with the light coming on at each startup. Thanks to all, particularly to 103west43rd, for your helpful advice.

103west43rd, With two out of two suffering from C127, it would seem that C127 must be inherent with the vehicle. I also checked my 2010 Transit Connect with an external UltraGauge tool connected to the OBDII access point and have had no trouble codes show up, although that system specifically specifies it is checking engine trouble codes. I checked this morning and the TPMS warning light flashes for precisely 70 seconds after start up and then changes to a steady light, exactly as you note. It would appear that I have the TPMS-to-controller network communication issue. Any idea what the resolution to that problem would be? Thanks for your continuing support!

103west43rd, I have repeated this interrogation sequence three times now today with the same result. After getting the gauge test, I press the trip odometer reset button 8 more times and get the message "dtc" followed by "C127". That sequence continues until I either remove the key or press the trip odometer reset button again to move on through the interrogation sequence. I have taken photographs of the instrument cluster with the "dtc" and "C127" but have so far been unable to post them here. Any other ideas?

Thank you, 103west43rd, for the procedure to find trouble codes ... and much additional information. I followed your procedure and had displayed DTC "C127". I have attempted to Google the code and have not found anything useful. You mention there are 20 potential TPMS trouble codes. Do I have one of them? Thanks for your help! Also, mustang, I am continuing to look for a bargain on TPMS sensors through the Internet in case this turns out to be the problem. $16 each for Ford sensors sounds like bargain. Thanks.

To respond to Mustang's reference to an Amazon offer for sale, this Amazon ad says it is a used sensor. Do I really want buy used sensors if they have batteries in them that only last 5 years? How old might the sensors be? Seems like I would do well to find new sensors with the latest possible production date. Also, I note that my estimated cost from Ford should have been $360 plus labor rather than $270 plus labor. Don't know why I was multiplying by 3 rather than 4.

Yes, the "alarm" I am seeing after startup is first a blinking tire warning light on the dash which subsequently turns to a solid yellow tire warning light on the dash.

I have a 2010 Transit Connect with 24,000 miles that has been remarkably trouble-free. However, recently the TPMS alarm has been on continuously. After checking air pressure in the tires numerous times and finding the pressure at or above the recommended pressures listed on the door pillar and after twice successfully resetting the TPMS system in accordance with the procedure in the Owner's Guide, the TPMS alarm is still on. I now believe there is a failure somewhere in the system. Perhaps the most likely source of the problem is a decayed battery in one or more of the tire sensors. I read on one website that the batteries typically last about 3-5 years. I have looked on the Ford website for parts and find new sensors (part 1A189) available for $90.02 each, presumably a total of $270 plus labor for replacement. That would go a long ways toward buying a new set of tires. I suppose I could do nothing and accept the continuous TPMS alarm. Do I have any other alternatives beside going to Ford and having all 4 TPMS sensors replaced? Could the problem be something other than the sensors? Bob in NC

When we returned home from being gone about 2 months, the Transit Connect would not start. I made reference to the Owners Manual and checked both keys. The result was the same. I had charged the battery for a short time with the Battery Tender. It showed the battery charge was near normal. I called the dealer and was asked that I report the problem through the Roadside Assistance system and have it taken to the dealer for checking. I did that and the Roadside Assistance program worked well. The Transit Connect was carried to the dealer on a rollback truck. Initial checking revealed the computer was not even on. They kept the Transit overnight after making a call to Ford technical assistance. Today the service representative called and said it was ready to be picked up. He said they had found out that the Transit and Focus computers are programmed to shut down if the vehicle had not been cranked in 50 days. The purpose is to save the battery and the computer memory. If this occurs, the computer can be restarted if the battery is disconnected for 2 minutes and then reconnected. They did this at the dealer and everything works as before. They are smarter and I am smarter. There was no mention of this in the Owners Manual. The shop work order refers to a document SSM21205 which presumably reveals this condition. For your information!

Relative to replacing the antenna, after adjusting the garage door opener to get the maximum opening, the Transit Connect van would go through with 1.7 inches clearance but the antenna whacked the opened door going in and out. After hearing of the poor reception resulting from installation of a shorter antenna, I decided not to do that. I thought about installing a magnet at the top of the van to hold the antenna closer to the roof, esentially bending it downward toward the roof so that it is no higher than the rear center brakelight. After looking for alternatives, I found a magnet at Lowe's that seemed like it might work without changing anything on the magnet or vehicle. I bought it for $2.78, tried it and it seems to work well. I have used it for about a week now and no issues have developed. As it is shiny metallic color, I have since painted it black to match the other trim. It may rust with time but for $3 I could buy another one. Better than replacing the antenna? Bob

Woody, Today, I again looked for a cabin air filter. On a hunch, I removed the passenger side cowling just below the windshield. Taking out 6 screws will allow the black plastic cowl to be removed. Voila! There in view is a filter-like device, but not a filter, I will call a non-filter. After trying to remove the non-filter and being unsuccessful, I took out 2 more screws holding a metal bracket just below the windshield. With that bracket removed, the non-filter can be readily removed. It is about the size of a cabin air filter but without the filter media. It is made out of plastic with large rectangular openings about 1/4" square. Adjacent to the right side of the non-filter is a screened opening to the driver side cowl volume. It is surrounded by a rubber gasket material and can be removed. The screen openings are also large, larger than in window screen material. On the driver side of the non-filter is another rubber gasketed device but this one is solid aluminum rather than screen material. It is meant to block air flow from that direction. Consequently, all the air entering the non-filter must come from the driver side cowl volume. This answers a few questions but begs a number of other questions. I checked with RockAuto, a filter supplier I have previously used to see if they have cabin air filters for the Transit Connect. They do list a cabin air filter for these vehicles. It would seem possible that a cabin air filter could be procured that would replace or be installed inside the non-filter. For some reason, Ford declined to install a filter in this area where a filter could be logically placed. I have taken several photos of this arrangement and will try to figure out how to upload them to make them available. Photo 00 shows the opening with the cowl removed. You can see the non-filter below the black bracket. Photo 01 shows the screen on the driver side of the non-filter. Photo 02 give another view of the screen and non-filter. Photo 03 shows all the parts removed including cowl, metal bracket, non-filter, gasketed screen, gasketed aluminum air blocker and fasteners. Photo 04 shows the opening with all parts removed. Photo 05 shows another view of the area with all parts removed. Curious! Bob

Barring evidence to the contrary, we shall assume there is no cabin air filter. I had expected that the Transit Connect would have one. Thanks for checking the manual and sharing my search on the vehicle. With appreciation, Bob

Does anyone out there know how to remove and replace the cabin air filter in the Transit Connect? Supposed to be inspected every 7,500 miles and changed at 15,000 miles. I typically do my own routine maintenance work but there seems to be no help from Ford for doing basic maintenance short of buying a shop manual. Thanks for your help!
