Hey guys been a long time, been really busy with my jobs and my Integra. She is a manuel and when i first start her, my idle is fine and is until Operating temp. As soon as it hits operating temp my idle surges up and down, and almost dies. I get a check engine for a TPS code P0122 i think but i replaced my tps sensor 3 times still no difference. I have also checked for vaccum leaks but have found none. Any other suggestings?

 

are the sensor connections switched? between the IAC and TPS? i forgot which ones exactly, but theres two of basically the same connector that tend to get switched by mistake.

 

Forgot to say i tried that also because i did it once. lol I switched them again and the car ran horrible so, the sensors are right.

 

Try checking and making sure it is set right. Sounds like it may be a little out of adjustment.

If it is set correct, then check the wires running to the sensor for damage.

 

Ok checked the tps and wiring and it loks fine, Things i noticed though are..

One: Throttle Body cable/where cable connects is sticky..
Two: My Idle is really fucked up now, at 90% of lights when i idle my car dies and its only running at 480-520 RPMS

Is it the Map sensor, or Idle control valve? Need some help, i was thinking about picking up a Map sensor at My Autozone today and trying it. Howver it says 3 door Integras and 4 door map sensors are different??!! I thought they were the same?

Thanks for the help guys..

Check engine codes are: P0107, P0108, PO122

Map/Baro CKT Low input, Same thing but also high input, andthrottle/pedal position sens a ckt Low input.

 

Have you reset the ecu after switching all the wires around for the test? I am unsure why you would be getting both the low/high readings. You could try removing the MAP and spraying a little carb cleaner in the TB passage. It may be a little restricted.

Do you have access to a multi-meter? Then you would be able to read what the TPS is saying. I could advise more if I knew the voltage coming from the sensors.

 

Yes, i have reset the ecu several times, after all the tests. Light will go off and then turn on again in a few seconds. I am aslo confused about the map sensor readings, as you said it can't be both. Although i thought my map sensor was duying about a month or two ago, replaced it from one at work. Ran a little better but not enough to keep map sensor so returned it. Damn should of just kept it.. I do have a multi-meter, i was going to try that next. From what i have heard its supposed to read 5v for each wire.

 

The CEL coming on that quickly sounds like a wiring issue(broken/damaged), but it wouldn't hurt to check the sensors.

At the MAP; disconnect it and with the key on engine off you should get about 5 volts between the Yellow/Red and Green/White. Plug it back in and you should get a change from 3.0v car not running; up to 0.5v running(depending on level of vacuum) between the Red/Green and a good body ground(not the wires).

The TPS: You should have around 5v between the +Yellow/Blue and -Green/Black wires. With engine off, throttle closed, TPS connected; there should be around 0.5v at the +Red/Black and a good ground. It should increase smoothly as you open the throttle to about 4.5v.

 

Ok what is/was wrong

Map sensor was dead/dying
Throttle body was sticky as hell now fine
I have a BIG ASS vaccum leak somwhere. (had to go to work so had no time to look) going to tommarow morning.

 

hi people i have a civic lsi with a b18c4 in which was kicking black smoke out bad over fueling something cronic so i decided to get throttle bodies and had a ecu mapped to run it wtihout a map sensor and its still doing the same also the engine management light is always on any one help??? post me or email
