Hello folks,

This message came up when starting the car, but then no check engine light or nothin’. Literally just popped up for a second then went away, but only when I started the car.

Should I be concerned? The car drives fine and like I said, no light. Turned it off and on to see if it came up again, but nope. Does anyone else have this occur to them?

This happened 1 other time like a year ago before I had the recall done, but IDK ??‍♂

Had this happen to me last winter, turned out to be the neutral sensor in the transmission (or something like that) that was either not working or out of spec.

No check engine, no stored codes, dealer found it right away with their tools though and repaired under warranty. Has not happened again since.

The message was also on for just about a second at startup exactly like you described, yellow with the little wrench icon.

You need to see if its logged a code. For that you need an OBD2 unit. Cheap on ebay and you can download a free app to at least see what the code is.
There is another thread here where a boost control solenoid was at fault but the car also had symptoms.

You need to scan it to pull the code. You can pull it with an AccessPort, if you have one. I got this warning on initial startup if I haven't started the car for a day or two.... and it started happening right after I swapped in a small battery. So I think I just need to get in Forscan and mess with the battery values. My code was P08B2.

This just started to happen to me also in cold weather only. The ODB2 I have doesn't pull any codes and the message disappears in a second or less. Not sure if it's just the battery as others say, but a 2016 still running original OEM battery is mighty suspect lol

I also had this problem. I brought it into the dealer and the battery failed the voltage test and it was replaced under warranty. They also replaced the battery cables. This fixed the problem. Another symptom the car had which I believe was related was the auto start/stop never worked, and now it does.

Has anyone successfully got rid of this message while running a smaller battery? I have an Odyssey PC680, and changed all 4 of the battery settings in FORScan to the smallest battery size (I think that was like 370 CCA, even though the PC680 is 170 CCA), but I'm still getting this warning. I even tried adding that extra ground cable.

Thanks @big jim. The battery was new and actually went down hill fast, which was from either my (non-Odyssey) battery charger or jump starts. It started off with me driving to an autocross, but my battery was dead when my run group was going and I had to get jumped. I've had to jump it several times since then. I ended up just going back to the original size, although I was a little tempted to get the parts for an ST battery box and going with an Odyssey PC1200 for it... but that would have cost me an extra $200 (~$100 for the box parts; +$100 for that battery). When I pulled the PC680 out it was very bloated and sad looking.

Sucks to hear. I've been waiting to switch to a smaller battery once by stock one gives out.
February will be 4 years with the OEM battery and I've been running a Thinkware Dash cam since then with Parking Mode Motion Detection.
I was just wanted to see if running a dash cam with the Odyssey battery will cause it to drain quickly. I don't want to be worried about a dead battery.

Anyone else have any issues with these smaller batteries?

if you have your rs in your garage...then keeping it charged is no prob at all.
I had a house/garage 2 yrs ago...but now I'm in an apartment bldg and I cant charge it while it's in the car. so I have 3 pc680s that I rotate every month. keeping 2 charged batteries in the apartment where its warm.
I takes me 15 mins to swap em. warmer weather seasons permits the battery to keep longer charge and I can go 3 months without having to swap. I daily drive mine...so that helps too.

I dont know how much power a dash cam would drain? but I'm guessing it wouldnt be a good combination. maybe the equivalent of having an interior light on? I think this would wear your battery out faster in the long term and you may need to replace in 6-9 months.
that's if you're charging every night in a garage. I'm just guessing though.

but it's a nice mod. I could feel the diff when I installed it. the car felt more nimble.

I think I liked the weight savings 2nd most, but the best thing I liked about the smaller battery was the space savings in the engine bay. It was probably my charger that helped end it... I've had it for a while and even though it does have a "deep cycle battery" mode, I think I went through the same thing with my other car. That one I did eventually just put a battery box in the trunk.

I do want to revisit this, but I needed my daily driver to be reliable again. I'm keeping my Mele battery mount... so after a while I'll check on that Odyssey battery charger you were talking about. If it was just weight savings I was after, Braille does sell a 10lb group 48 battery that should fit our OEM battery box.... but for $1500!

I have this again all the time lately, been fixed back in 2019 and it’s back now!

My OBD scanner wont read the code associated to this issue but the dealer pulled the code when they replaced my catalytic converter last december. I told them not to touch this issue at the time given it doesnt really affect anything. I have the same symptoms associated to the neutral position switch where the idle will raise when releasing the clutch even in neutral sometimes. And if parked in reverse sometimes the camera will stay on (with the reverse lights) when hitting the road until the car notices the faut and turns both of them off)…

Anyways I too need to change my original battery soon (2016) but I guess to answer your question if it has anything to do with my initial issue in 2019 the sensor was about 30$ I believe but perhaps just cleaning it first might help. There is another thread about this somewhere with more details on sensor location.

Hmm interesting, the dealer also changed my catalytic converter last November! Maybe they damaged the transmission sensor? Looks like I'll need to take it to the dealer to confirm this is the problem.

Does anyone have information on this? I am having the same problem. It is more evident when its cold which makes me think of Battery. One other thing I have noticed if I sit in the car and give it a few seconds it will occur less. It seems like the car has time to initiate before starting. This has happened since I owned the car.

Morning! Same message on startup on my 2018 for a while . So waited until I had the car in for scheduled service last week.my local ford team said it’s a warranty item . The fault is diagnosed and the fix required is a new Neutral Position Switch. Parts are on back order won’t be ready until December 29.

Havent fixed it yet I only get the message once in a while and it does not affect driveability.

It was fixed once a few years ago and they replaced the neutral position sensor/switch (or something of that sort).

They told me parts were like 30$ last time I checked but dont have the PN available to confirm.
 
#36 ·
yes couple of weeks now have had same message on startup. Had the car in did service the ford guys say it is the neutral position switch. My car goes in to have the fix done on December 29. I’ll send out the part number once I get the car back.

Engine fault service now code - done !! Hopefully my final update! I got the RS back on Friday . After the codes were first investigated about two months ago, fast forward to now. Under the extended warranty a PCM unit was fitted. Glad to say though it needed a good run on the highway I think my pride and joy is back! No more warnings on !
