Hey guy, my 05 TL only has about 64k on it, but I am starting to think about the APP sensor.

You can read more in this awesome thread (which you should read anyway)
https://acurazine.com/forums/showthr...=704808&page=3

Is it almost guaranteed to fail? As in, should I be carrying an extra one around in my car in case I get stranded on the road? I guess it couldn't hurt but I am wondering how common this actually is.

Thanks!

dont think you'll get stranded, as if and when your APP sensor fails, the car will go into limp mode

duffduffxx

Limp means that it will just limp to a shop?

justnspace

iTrader: (1)

correct sir, it will limit your speeds and RPM just enough for you to limp to a shop.


I also dont think its a wide spread problem. yes we hear it more often, because a forum is used to tell about and ask about problems.

my 06 has 40k on the clock and im not worried about the app sensor.

but now that you do know the symptoms of an APP sensor fail, if it ever happened to you, you can diagnose and fix the problem swiftly.

This is why I love this forum and never go to the stealership

I don't know about "guaranteed", but there has been a noticeable failure rate of this part. Combine that with the fact that the part was/(is?) on national back order tells more of the story.

iTrader: (1)

is it still on back order?

nfnsquared

Don't know, that's why I put the "?" after "is". As of about a month ago, it was.

gotcha, time to do some calling.

how many miles are on your car? and has the app senser went?

duffduffxx

I just checked on Delray, doesnt seem to be out of stock....

nfnsquared

I'm at about 106,6XX. No, I haven't even got a CEL in all those miles, but reading all the APP failures here on Azine has caught my eye...

justnspace

iTrader: (1)

then I'm not worried.
its only widespread on Azine.
and it can be a foreshadowing event, but as long as we know the symptoms it'd be an easy problem to fix.

Might be a stupid question but what is the APP sensor? And what does it do? I may just order on and throw it in my tool box in case it ever goes!

justnspace

iTrader: (1)

search and read.
the OP provided a link, then if you're still curious you can continue to find more about it.


found these quotes by searching for "APP sensor"

nfnsquared

I'd be lying if I told you I haven't considered doing that...

although it is not a common problem, it does happen. what makes some go faster than others? im not sure. My buddies sensor went at about roughly 70k.. I dont think this is something we need to keep on reserve, but if the symptoms ever come up atleast we know what the problem is..

I read the last page of that thread...and had commented earlier on it, where does it say what the APP sensor is?

friesm2000

iTrader: (4)

not quite sure either




but for the OP, very few sensor failure will leave you stranded (something like a alternator or battery will though), the engine may run like shit and limit you in speed, but it will still at least get you to safety (maybe not the dealer especially if far away, mainly thinking like a gas station where there is a phone and warmth, and you can wait for a tow truck)

Comptechtl2367

Thanks, I read it twice and no where does it say what the sensor does... So ill ask again and hopefully not get a smart ass answer!

justnspace

iTrader: (1)

Here's your smartass answer!

please refer to post #14.
I did the hard work for you and quoted several people on what the APP sensor does, and what code is thrown and how to fix.
kthxbye

A little more detail: Accelerator Pedal Position Sensor.

Has an A and B sensor. It sends variable voltage signal to the ECM/PCM based on accelerator pedal movement. The ECM/PCM then in turn moves throttle valve based on voltage signal received from APP sensor.

The ECM/PCM compares the voltage signals it receives from each sensor (A and B). If the voltage is different, it puts the car in limp mode.

was going to say that also, but already said though

I replaced mine back in October. It is located right below the front strut bar in the middle. Be sure that if you are ever replacing it that the car is cooled down or burn you will receive. Mine crapped out at around 68k. Since the part was on backorder then as well I had to drive (as little I could) on limp mode for two weeks. But I did find out that if you do go into limp mode, simply pull over and turn off the car, wait ten seconds, and turn it back on and it will run fine then. But if this happens be careful not to gun it or you will cause the car to go right back into limp mode again. Anyway, my two cents... any questions you can ask, I've been there done that...

PS new app sensor made the car feel brand new again.

Wow...may have to look into that.
I'll spare a snide response to the smartass answer since you did actually answer my question. I didn't feel like rereading an entire thread looking for a needle...figured there would be some members on this thread that would be able to simply tell me what it was without having to back and look it up.

kthnxcya.

I also found that turning off VSA will prevent it going back into limp mode...not the best solution, but it will keep you moving until you can get the sensor replaced

brockmari

It did not work for me. I turned off VSA but same thing happened, VSA, ! and engine lights on, car went into limp mode and had to pull over and restart to get running again.

aacura98

I got a couple of limp modes and I was reading last night and I seen one quote regarding tightening the cable. I did tighten the cable and pick up the slack last night and drove the car whole day today so far so good. Im goiing to drive more this week and see before replacing the APP unit.

brockmari

After the dealership advised me that they could find nothing wrong with my car and would not be able to diagnose the problem unless I got the car there before the check engine codes erased themselves, I went and got my own OBD2 reader. The code was 2183. So I then got myself a new sensor from AcuraOEMparts.com ($140 including shipping and handling) and replaced the part myself. I am not a mechanic, but I got up the courage thanks to the excellent photos on another thread https://acurazine.com/forums/3g-tl-problems-fixes-114/diy-app-sensor-730958/#post11244755. It was so easy! Now the problem is gone and the car runs smoother now than it has for years! This is a great web site!

I had a more subtle failure on my Accelerator pedal position sensor. As I've read from others, the car felt a slight drag and speed variation cruisng at 70ish. Sort of an off off hesitation. I kept driving it that way for a few months and one day I had the check eng went on along with VSA light and it went into limp mode briefly. I stopped the motor and popped the hood looking for something obvious, like a burned up engine or oil leak. When I restarted it seemed okay. I got ahold of a code reader and shore enough it was the APP sensor code which I ordered from Del Ray at $140.00. I'm a true novice at working on modern vehicles and it probably took me 1/2 an hour since I was figuring things out as I went. It would take 10 mins to due it again. Agree with others. The new switch seemed to allow better acceleration at all speeds so likely this was going for a while. My 04 tsx has 103k on it and I've suffered many of the common issues of the last 4 years such as radio lights, lock accuator, repetitive blown accessory fuses and a couple of recall issues but it is a nice car and fun to drive. I had to panic brake it the other day to avoid a $%&wad stopping for no reason and I was very impressed with the combo of those big wide paws and antilock brakes which made for a very fast and very controlled stop. nice.....

I'm having similar symptoms now, and I'm @ 100,7xx miles......coincidence?

Got the code VSA and engine check light. Went into limp mode. Code read 2138 throttle body Scanned the car did live test of the pedal 8.6%-92.5%. Ordered the Sensor as well the throttle body unit. Acura Dealer quoted me $900 with entire unit. Telling me Acura only sells it together not the sensor separately. Called Honda dealer they quoted me $350 same part entire unit, sensor itself $250. Found same unit sensor for $60 throttle body unit, sensor $25 all delivered.

^^^where and did it solve your problem?

49er

Haven't got the part yet. Had the check engine light cleared came on again with VSA and limp mode. Will only drive short trips until the part arrives late this month so i can install it. Wait and see if it corrects the problem.

vpasla1

wouldn't hurt to tighten the wire to the app sensor as a temporary fix. May help.

49er

Installed new TPS sensor and throttle body for $60 cleared codes after driving for week no check engine or trouble codes. Can't believe Acura dealers wanted $900 for entire throttle unit and sensor or Honda wanted $350 for entire throttle unit and $250 for only the sensor.
Bought the sensor only for only $16 wanting to install on old throttle unit. When my multimeter arrives which i ordered how do i adjust the sensor resistance to 41 ohms. Or do i adjust the voltage on old throttle body part.
Always nice to have spare TPS unit in case the new one fails at some point or i can sell it as refurbished part.

Now you know why they call them stealerships.
