Hey guys,

I'm new here so bare with me. I've never encountered this until recently.

I was driving to work on the expressway this morning and when I hit the gas pedal to the floor, the engine was high revving then suddenly went into I guess what's called Limp Mode (wont rev higher than 3k RPM). I pulled over to the shoulder and checked everything out. Hoses were intact, fluids were good, etc. I turned the car off and turned it back on and it was fine for about 5 minutes until I went heavier on the gas pedal again then back to Limp Mode again.

Car: 2010 Acura TSX AT 4-cylinder (currently stock)

Symptons:

*CEL is on solid (has been for 2 weeks, there were no issues prior to last night)

* When at Full Throttle in low gear it seems to be hesitant on pick up, almost as if it's starting at 2nd or 3rd gear.

*On highway, at Full Throttle the RPM's would rise but no powerband kicking in. Until last night when I first experienced the Limp Mode action.


A few things I tried:

*replacing the DBW fuse

*ECU reset (key in 2nd position, foot on gas pedal method)


I'm leaving work in an hour to work on the problem and have the CEL read. The only thing I was able to find relative in the threads is that it can be the APP sensor. Any other ideas or areas I should be checking? Any info is helpful and once I get the CEL codes, I will upload those on here as well. Last time I ran into this sort of situation is when I blew the tranny on my previous Cadillac but that was years ago and was rather evident that I blew it. I don't think that this is the case here. Do you think a manual ECU reset via disconnecting the battery may help the ECU reconfig itself?

Appreciate everything gents.

So just got the CEL checked...

P0341 - CMP sensor incorrect phase detected

P1129 - MAP sensor signal higher than expected


Searching for resolutions currently but not having too much luck.

I am currently having the same problem on my 05 tsx but i just got done replacing the app sensor. Thought everything was good. Felt like is was shifting smoother untill i hit the floor trying to beat someone at the light n once i came to a stop car started shaking engine n vsa light came on. N it sounded n felt like the engine wanted to cut off...pulled over shut the car off unhooked the battery for like 2 seconds n put it bck. Its bck to normal now but i know its only until i gotta touch that floor again...will try looking 4 other things that could cause this n let u know wat i find
