Changed App sensor and throttle body help!!!
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 has anyone ever had a plenum malfunction? The car is a 2005 TL 6 speed. Any help will be greatly appreciated.

Moderator Note: Thread moved to model specific thread.

 

Little off topic - from my experience, nobody does it without reason and the less probable reason is that the bulb died. The bulbs on dashboard are to signal initial check and sudden failure of systems, circuits etc. If somebody sells the car without any of those bulbs, they try to hide something.... and don't believe explanations that the bulb is there but just burnt out - check it, even if you would have to remove the dashboard. If you know the previous owner, call him and ask what really happened.

 

What exact code does it come up? Original parts were used?

Aren't all of gauge cluster "bulbs" actually LEDs?

 

Yeah there's no easy way to remove the cluster lights

 

Sorry to be unhelpful, but I am definitely curious about why someone would remove the vsa light cluster I can only imagine the kind of pain in the ass that would be... I think I saw someone else already ask but what's the code it's giving? And did you say you've swapped PCM's twice?

 

has anyone mentioned oil level?

 

what's the code you are getting exactly? Did they do the throttle body relearn procedure?

 

repost...

 

i actually opened up the cluster to check and see and the vsa bulb was taken out and the abs bulb

 

yea i swapped out the PCM twice first time i bought it off someone use second time my mechanic sourced it out for me not sure exactly what code id have to call and check but it always comes up as APP sensor i can only think someone would do that if the vsa or abs was actually giving them problems

 

oil levels are good i check them regularly because the car leaks oil but i have to add almost two quarts between oil changes

 

they did the throttle body relearn. And they even updated the software i believe Acura had put out. Not sire exactly what specific code ill have to ask and get back to you

 

My car is still in the shop its been there for over a month and they cant figure it out any suggestions or a shot in the dark would be greatly appreciated

 

lol i call bs

 

follow up question, while you were in there, did you replace the bulbs?

 

i did not replace the light not sure how to look for them online but it looks like someone forcefully pulled them out with pliers as there are scuff marks around the opening
On another note
Mechanic is telling me there is a short somewhere in the harness that he cannot find. He said hes patched up wires in the harness but theres still a short somewhere .....now the car is completely stuck in limp mode and wont go back to normal even when car is restarted. A brand new throttle body was installed from acura and he said the car fried/shorted it right away (ruining a $600 throttle body) and now may not even be able to get it replaced under warranty..... he is suggesting i replace both engine harness and interior harness costing me another $1500 just in parts but idk if that's a reasonable conclusion.

 

sell the car

 

Yes yes, but try to make it drive even for a while. And don't tell anything to the buyer like previous owner did.

Damn. Where did you get this car? Or from whom? If it is forum user, they should be banned for a lifetime.
The clues that you mention here prove that somebody mislead you on purpose and exposed you to accident risk that could threaten your life. When did you buy the car? Do you have any written evidence of car purchase? Here in Poland the car sell-purchase contract includes the statement of the seller that there are no defects they are aware of. The evidences you describe prove the misleading was intended. So if in Poland that would be the point to try to regress to seller, I'm sure in US it would succeed.

 

When mine did this, it was the EGR valve. New one is pretty pricey, so just removed it and cleaned it out really good and my car has been running great since. Its easily accessible at the front of the engine, so something you might want to try.

 

I just got the car back recently...... the code that keeps coming up is P2135 car was good for a couple days but it went back into limp mode a couple of times if i turn the car off and restart it limp mode shuts off and i can continue driving......but damn this is getting annoying

 

So i was told that the ecu that was out into the car is from an automatic, now im being told i have to source out an 05 MT ecu i want to know if an 04 MT ecu could work or would it be better to get an 08 types mt ecu and flashpro it 🤔 another thing 02 sensor Bank 1 sensor two is malfunctioning could that cause limp mode?

 

Finally found 05 manual ecu, was able to sync up immobilizer with a foxwell scanner, but car is still throwing codes had to replace fuel pump relay because the one installed was not the correct one. Now im still getting a bunch of codes from the MCIU unit and from the abs pump, as well as a/b throttle correlation code and now im getting O2 sensor bank 1 sensor 2 code..... car has been running a bit rough since before the ecu swap and went into limp mode once with the new ecu...... i ordered two more relays for main relay and one for ignition coils maybe they are shorting out or something.......have also read that low transmission fluid can cause limp mode but im not sure if thats the same for a manual ill changing the fluid out soon.... i also need new motor mounts but that shouldnt effect much in terms of limp mode activation right? Any comments or ideas are greatly appreciated

 

Just curious, and don’t know if it has any correlation…but how is the battery, and connections to the battery? Also grounds in the engine bay?

I’m shooting in the dark, I am no mechanic.
