today i started my car and it gave me a check starter light on the multi display screen. the CEL is on and i can drive normally for about a minute until the VSA light turns on and the car goes into limp mode. is this because my ive been putting my oil change off for a while? i scheduled an oil change for this thursday because it was getting pretty low. i searched the forums and people say it could be a APP failure?

i reset my maintenance minders and the check starter indicator turned off for good but the CEL and vsa are still on

im going to have to ask midas to look into it when i get my oil change there

is it possible that my old oil is causing all of these problems? the car was perfectly fine yesterday

Check the oil level now.
if it is low, add oil.

csmeance

how long have you had the oil in the car for? What kind of oil is it? (midas oil or the factory filled stuff)? Also has you car been running rough? Also check the oil dipstick, is the car low on oil?

I'd go to your nearest autozone/pepboys and they can pull the CEL code for you. Post it here!

nfnsquared

What do you mean by low? Do you mean the oil life indicator or the actual oil level?

What the heck is the "check starter" light?

Yeah, it could be an APP sensor failure. What year is your car?

You need to drive to Autozone or somewhere and have the code/s read....

gcxandrew

my cars 2007 with 50k miles. i have a midas appointment on thursday im gonna tell them to check it. i really dunno what the check starter thign was about but its gone now. you think midas would be able to fix the APP or is it like a dealer specific job?

thanks for the help everyone

csmeance

I wouldn't even let midas touch my lawnmower! They have some shady service across the US!

Can you answer these questions so we can better help you:
1. Is the oil Low on the DIPSTICK or low according to the MID?
2. How long have you had the oil in the car? (5K miles, 10K, 15K?)
3. Have you had any sort of services at the dealer?
4. Did the car start properly when it gave you that "check starter" message?
5. What type of oil are you using? (the stuff midas puts in, oil you supply, Mobil 1, etc?)

nfnsquared

OK, not totally familiar with the messages on 2007 MID. Anyone else confirm that the 2007 has a "check starter" message?

I'd be surprised that an APP sensor went out already on a 2007. I think they are mostly failing on 2004's so far. Why wait until Thursday? Just go down to Autozone and have them read the code for free. Write back when you have the code.

Also, you didn't answer my question about what you meant by "low".

dont let midas even touch your exhaust,,, let alone a ck engine code or tightening the oil drain plug to 29 foot pounds--not 100

running rough? It needs a new engine sir

are you unfamiiar with the story of king midas --everything he touched turned to gold

do you want them touching your car,,, NO ..or the repair will cost gold!!

any major name parts store will ck the codes for free, some may even look them up for you, or you google them
codes are clues... not diagnosis

a lot of things are covered on emission warranty which goes to 80

do NOT drive in limp mode--its to get you off the freeway to safely park and wait for the tow

My APP sensor failed couple weeks ago..my car is 07 base and around 54xxxx when it failed...it went to limp mode..CEL and VSA light came on ...went to eat,came back and car drove normal...VSA light gone..CEL was still there.

gcxandrew

ok im pretty sure its not the oil because it was maybe ~8% life left. the "check starting system" indicator went back on though and my car runs normally now except the CEL is still on... it sounds like APP failure but whats with this check starting system light?? theres no post about it anywhere

legendbliss

it doesn't matter if its at 8%. physically check the dipstick to make sure oil is full and make sure you're not leaking oil or anything.

erick3

warranty dealership run? your dealership might be nice and cover it under warranty even if you're a bit past 50k.




you take your car to midas? -_-

Majofo

It's more than likely your app sensor. Get the code read at Autozone for free.

gcxandrew

went to auto zone today in full power mode and got the code u0107

searched google and these forums and nothing really comes up.. the autozone guy said theres nothing on their files with this code too. wth is going on?

nfnsquared

"Lost Communication With Throttle Actuator Control Module"

Sounds like a bad APP sensor?? Apparently it's a dual unit and when one can't talk to the other, it'll throw a code:

http://www.aboutautomobile.com/DTC/U0107

Majofo

hmm.. typical app failure code is P2135

Could be a battery issue.. check your pcm as well and make sure there's no moisture in that area. Remove the kick panel in the passenger footwell. It'll be near the firewall run to the end of the center console.

nfnsquared

Yeah, a bit confusing. Never seen this code.

Found this also:

Lost Communication With Throttle Actuator Control Module No

Talks about faulty TAC (drive by wire) unit associated with this code. The APP sensor is the equivalent in the TL, is it not?

Not sure what to make of it, but the above fits...although different from what others with APP sensor failures have seen. Could also be a bad PCM or CANBUS circuit fault. PCM is expensive and not user friendly to replace. APP sensor is comparatively cheap ($130, I think) and easy to replace yourself.

If you have moisture on the passenger side carpet, then I'd lean toward PCM.

Good job guys.

bookmarked.

nfnsquared

OK, two other threads on U0107 where an initial diagnosis is made but the final fix is never known:

https://acurazine.com/forums/3g-tl-2004-2008-93/my-first-drive-my-tl-739360/

Suggests bad APP sensor....

And this one:

https://acurazine.com/forums/3g-tl-problems-fixes-114/car-doesnt-start-check-engine-then-stalled-624577/

Suggests bad battery....

I'd have Autozone or someone check your battery and charging system first. That would be the cheapest and easiest fix.

I'd also send a PM to those two members and ask them what the final determination was. Good luck!

nfnsquared

Hmmm...So now I'm even more confused....

The service manual procedure doesn't say a thing about the battery or APP sensor in the troubleshooting procedure for a U0107 code.

It has steps to check circuit/bus continuity, check/replace the TAC module (which is indeed separate from the APP sensor), check/replace the PCM....

but nothing about battery or APP sensor.

One easy step is to check fuse #1 (15A) in the under hood fuse box.

If you think you want to tackle this yourself, I'll be happy to post the scans from the service manual (it's 7 pages and 57 steps).

Dude you take your car to Midas ? ? WTF? Are you crazy ? ? Honestly no wonder people have problems with their cars! Good luck... but from now on man take it to your Acura Dealer! Yikes!

gcxandrew

haha guys i havent taken my car to midas yet all i wanted was an oil change and tire rotation from them anyway but this prob showed up. i have an appointment at 10 am at the dealership tomorrow

its even weirder now cause the CEL is off now and the car is perfectly fine.. maybe its a bad battery or something? has anyone heard of the CEL temporarily turning off for an APP failure?

i hope the dealer doesnt overcharge me to see whats going on with the car

thanks for all the help i really appreciate it

do you guys think the LEDS i have messed something up electronically and the computer noticed that it was fine after a bit? i actually let my friend drive the car down the street the day before this happened maybe she didnt start it right or something?

gcxandrew

took it to the dealer today and the dealer said if the CEL turns off by itself then the car probably already checked itself 3 times before it turned it off and it should be fine. he said if it turns on again then i should come back. really weird i ended up getting my oil change and tire rotation done there instead cause all the crap you guys give midas haha

nfnsquared

Good deal, maybe you'll never see it again, who knows.

As far as Midas, IMHO they'd be fine for oil change/tire rotation. I think some folks thought you were going to let them try to diagnose your code...

Monty3497

I had the exact same problem, changed the app sensor, car was fine. App sensor....easy fix, it took 10-15 minutes.

bndit004

Ok all i may be a little thick but what is the APP sensor and were is it located? I'm having a little trouble figuring this out, sorry I usually know my way around cars.

nfnsquared

under the hood near the fire wall. just do a search for "app sensor" and you'll find the service manual scans.

MiaQbn23

The CEL might have been cleared by the person at Auto Zone when they pulled the code for you... This happen to me and the dealer could not figure out what was wrong with the car.

Nighthawkmurder

So ive been dealing with this problem for a little over 6 months. I took it to 3 different mechanics and no one was able to figure it out. I changed the pcm twice, app sensor was changed twice and so was the throttle body. All fuses and relays have been checked and wiring has been repaired but still has the same problem. The car doesnt have a vsa light in the cluster the previous owner removed the bulb not sure if the vsa can affect it or not. Bearing was changed and speed sensor on drivers side. Only 1 code comes up when im limp mode and its for app sensor but both have been changed twice can anyone point me in the right direction almost ready to give up on the car. The car is a 2005 TL 6 speed. Any help will be greatly appreciated.
