I've cleaned the throttle body I've cleaned the upper manifold to the throttle body I've replaced the idle air control valve I have not cleaned the bottom of the intake manifold.
Idles fine about 1000rpms
When I push the throttle open it's runs bad, roms up and down up and down. (Tried posting my video but it's not letting me post it not sure why still looking into that)
Cleaned EGR have me one coming, new pvc valve also.
When I first took intake of to replace the IACV they sent wrong one, so reattached that's when it started acting up. Just figured it didn't like me cleaning it idk and figured the new IACV would fix it.
Dinner help post the vid I'll post itThanks

 

Check to make sure that you didn't mix up the two 3 wire TPS and MAP sensor connections IIRC they are the same style connector and an be hooked up incorrectly.

Not sure what Accord you have, but this is the wiring for most Accords

TPS connector has 3 wires = GRN/BLU - RED/BLK - YEL/BLU
MAP connector has 3 wires = YEL/WHT - GRN/WHT - WHT/YEL

If you can't see the wire colours just swap the connectors anyway, then start the engine and see if that fixes your issue.

 

I'll check that thxSomeone said I also need to reset the throttle body again after cleaningThx again

Yeah you should reset the ECU/disconnect the (-) battery cable for 5 min, then start the car and let it idle for 5-20 minutes (until both fans come on) with no electrical accessories on. That's about the extent of the 2002 idle learn procedure.

Unless you adjusted the idle stop screw or remove the TPS, there is nothing that requires reset on the throttle body. The idle relearn is for the Rotary Air Control Valve (RACV), also known as the idle air control (IAC) and fast idle valve (FITV) on previous gen Accords. From 98-02 they were combined into one component.

 

Tried and switched plugs around wouldn't start.
Back to original plug plugged in it starts.

Back issuesDriving it you can barely touch the pedal to go down the road.
Will start like normal unless you press the pedal at all then it won't start.
Still not sure on how to reset the TPS ,
Seen and read several ways no luck yet. Purged the cooking system as well.

 

Did you remove the TPS from he throttle body?

 

Ok I'm going to recheck that cause I just tried a check on the connection going by YouTube video saying to test the red wire and check the volts. I believe video said 5 volts wide open and. 0.45 I think for closed, but I couldn't get those readings from the connection I had connected. So I checked the plug I had stretched to map sensor and was able to get pretty close.
Anyway when I swap them around it won't start.
Ok I'm going to look at the manual see if it tells me the colors for the wires.

Red/greenYellow/redWhite/green
I'll check the other plug tomorrow and see what colors

 

1. I've replaced the idle air control valve2. Cleaned top plenum out3. Replaced map sensor4. Switched the two connecters (possible mix up) one is blue other is grey.
5. Pcv valve6. Sprayed around with carb cleaner to see if any vacuum leaks no luck there.
there7. Last codes I had were
p0113 (air temp circuit high)
P0505 idle air control system
P1519 IAC valve circuit failure
P1167 primary o2 sensor heater malfunction
P0325 knock sensor circuit 1 bank 1 or single sensor ( I've replaced the both several times upstream and down steam)
Cleared codes removed fuse and neg battery cable, went for a walk let it run for about 15 to 20 min maybeDon't see any changes.
The plug I tested get plug ignition onWe're
red/green 4.68
Yellow/red 0.04
White/green 5.09
Have not checked the other connection as of yet.

 

Yes replaced with me one. I'm thinking of putting old one back on to see if anything changes

 

Yes pot new one on

 

With the ignition on engine off, with (+) lead of your voltmeter reading (back probe) the RED/BLK TPS signal wire and the other probe (-) to chassis ground, you should have the following voltages;

Closed throttle - 0.5v (approx.)
Wide open throttle - 4.5v (approx.)
you should see a clean sweep of voltage from 0.5v thru to 4.5v when you manually turn the throttle from closed throttle up to WOT position.

 

OkTPSSensor wires are blue connectorGreen/blackRed/blackYellow/blackTPS Plugged in testGreen/black 0 volts
red/black 04.5 volts open 00.4 closed
TPS not plugged in testGreen/black 00.0 voltsRed/black 00.1 volts
Yellow/Black 05.0 volts
​​​​​​I've checked Haynes and the wires colors are correct.
what isn't right is when I plug the correct plug onto correct spot it won't start.
I switched the TPS and map sensor around incorrectly according to the wire colors and it starts and that's about it can barely drive it at all.
Ok switched to correct plugs to correct spot won't start.

MAP sensor testDisconnected
Should be 5.0 volts
Test 04.6 voltsConnected map sensor plug test should read 2.5 to 3.5 volts
Mine 05.0 volts
I've put primal TPS back on sale results as for running when plugs are plugged incorrectly it idles and won't start if plugged in correctly.
I've also replaced the heated sensor on the driver side of plenum sad well
last codes I had wereP0113
P0505
P1519
P0325 which has been on since bought the car and replaced several sensors no luck yetP1167
I took a walk the other day with the dog down the road for about 15-20 minutes left the car ready and come back I didn't have any error codes but it was plugged in incorrectly to get it to run.
Pulled fuse, pulled batt cable as well

Motor is F23A1Vin1HGCG32642A013358

I'm at a loss of what to do I seen on eBay some company will take your computer and test it if it tests good they won't charge you if it does test bad they charge you I mean it's like 170 bucks the ratings are good I don't know what else to do that's I run it into a shop somewhere right now I've been throwing parts at it it's not working.

All of this started when I started messing with it I got an error code that said something about the idle control valve so I bought one I had to remain still replace the car a couple weeks go find took the throttle body off while I had it off I cleaned it I also cleaned the upper intake plenum I didn't clean the bottom one I replaced the idle air control valve ever since then it's been doing this.
I don't know maybe I've tried the computer I don't know if I did it wouldn't run would it I don't know my next step would be maybe to send the computer in to the place on eBay and see if they'll tell me if it's good or bad I don't know what's involved with replacing the computer. I just put new struts on it I just put upper control arms I got about eight more pieces to put on the front end everything else on the hood is pretty much new or replaced

 

Want sure how to add this to lay post. I wanted to ask if everybody could send a picture of the TPS clip or socket what color it is and the map sensor socket what color it is and possibly the wires or which ones connected to which I'm trying to find out what mine wired up backwards or not.
still trying to check vacume lines as well but having little trouble with back side of plenum. TPS had 3 of them.
The three small vacuum lines on top shouldn't matter should it? They all go to the same spot on the top of the intake plenum.
