I worked on AC in 2005 Acura TL, after which I keep getting the code p2552. check engine lights are on and car won't accelerate at all. All the connectors are in correctly and fully seated on the harness. If i disconnect the battery and drive it's fine but when i turn it off and back on CEL come back on.
How do I resolved it

 

What kind of work did you do?

The relay that this code relates to is behind the glove box, in front of the cabin filter housing.
Relay gets power from under-dash fuse #1 (15A) which should have battery voltage all the time - check both sides of the fuse with test light
Power from the relay goes to the throttle control module, which is also behind the glove box.

So check fuse first, then relay, then the control module. Get yourself a service manual and diagram to make life easier.
