Hi guys I'm new to this forum , signed up here with no intention of posting anything but then this happens
So we jut picked up 2016 EX-L with 37k on it so wife drove it around and said AC not blowing cold so I went around and started checking, found one relay that wasn't working it had a hole in its shell looks like someone poked it with something . So while was sitting car idling three lights came on LCW failed and LDW failed and traction control light and check engine light also .So I made the guy scane it and 3 codes came up ( same code 3 times )he also stated looks like they were there previously ETCS or P1659. And I noticed the rpms was staying over 1k and when I pressed on the paddle didn't seem like it did anything. So the guy erased the codes I drove home , no issues. Then later when I started car up the same lights came on again.So what can it be ? Is there a fuse for the throttle body ? Is the accelerate pedal bad? Or there something else?

When your lcd/lcw comes on I would check your brake fluid level. Idk it's weird but, I've had to do this to a couple of vans. Put a little brake fluid in and all the problems go away (lol) I scratched my head on that one. [emoji2369] As for your other problem, it's definitely your throttle body.
Could be some of these. I just copied and pasted. Didn't want to type all of it. Will have to test connections, relays and parts.

Faulty Electronic Throttle Control System (ETCS) Relay

Electronic Throttle Control System (ETCS) Relay harness is open or shorted

Electronic Throttle Control System (ETCS) Relay circuit poor electrical connection

Faulty Powertrain Control Module (PCM)

I'll check the fluid level, now its get me thinking I was sitting down hill on parking lot while car was running when the lights came on , also I'll try to switch out the ETCS relay may be I did something when I was pulling the other ones out

Yeah could be. Turn the car off before you switch the relays.

I just did also added some brake fluid too, no change car automatically idales like 1200 rpms and when I press the gas padal it had little to no response at all...is there any other fuses I should check

 

Did you test the relays? Probably need a test light. Sometimes one of them goes and you have to replace one of them. I had to do this to a Ridgeline with the same issue.

Not with a light dont think I have one might have to run to auto zone and get one , when I get one how do I exactly test it ?

 

Their are small circular indentations on the tops of the fuses for the smaller ones and for the relays you need a voltage meter. You can make them work with that with resistance.

Go to YouTube. Ratchets and wrenches- "how to test 3, 4 and 5 prong relays" good video to watch

I would also check connections to your throttle body and see of any got chewed up by a squirrel or something. Sometimes that happens but highly doubt it

K I'll do that, any specific fuses I should look ? Also I just remembered that I previously removed "idale speed control " thing when I was removing power steering pump and I reinstalled it most likely I didn't put that half moon teeth in same setting maybe, after reinstalling it the car ran fine I drove it for few days.

That more than likely could have messed up your throttle control. Would just have to go to Honda to have your idle relearned

So I just took that piece off to see if I can re align it, theres no guides on it its wierd I can spin that half moon piece on the engine side to what ever position and still install it, do u know does it self adjusts?

Did you get a p0507 code when this all happened? Of not than I don't think that the idle control would be the issue

Took it off and repositioned it . No change still getting LCW system failed on the dash and with the rest of the lights on

 

Lcw of for the crash sensors. More than likely you have a sonar sensor in the rear that is bad. Their is one in the front of the car and the top of the windshield

No , only codes that came up when he scanned it at auto zone is 3 code all the same ETCS that's it . So he erased it than lights went off I drove it home no issues the Ac still didn't work so I took the front bumper off to see find the ambient temp sensor because I don't have any temp showing on the dash it shows -40 when I turn the ignition on so I think I found the problem who ever had the car previously never installed that sensor I found taped up wires with a connector on it but no sensor, no one have it in stock here all special order so when I get one on Monday hopefully that will fix the AC not blowing cold..

 

Wow good catch! I hope you don't have a D3 flashing on the dash do you with all the other light's?

Sent from my Pixel 2 XL using Tapatalk

 

Where is the sensor in the rear is it the rear camera ? The front one is right behind rear view mirror right?

 

What's D3

 

Drive 3 is for towing. It stays in the lower gear and down not shift up to 5th. D3 flashing woudo indicate a bad trans just from experience with slot of other codes. I don't think you do have that but need to ask

Thanks for the pic! I will see what else it could be

O yeah just checked all the fuses all good on that part too, still need to do the relay check

 

Ok good. Does your Odyssey have lane change sensors or any other lane diversion or anti-crash where the van brakes for you so you don't crash? Might be able to turn this all off. I can't remember if the Manual tells you anything.

Buttons like this?

I shifted fine when we drove around no issues there , only thing my wife just told me last Friday when she was driving, she was switching lanes she got to close to the car she said and something started beeping. The car drove fine after that she said slight delay in acceleration she said I think she just got to used to driving traverse that we had before this one ,( on my opinion the Chevy did shift better smooth between gears then this ody I think that Hondas do that )

 

That's normal it's the sensors taking over to slow the vehicle down and avoid collision.

Only has LDW and traction buttons

 

 

I think it's way to much technology for my wife to use anyways all these sensors and power everything our previous car was LS travese no issues on it we drove it for few years , so easy to use it too.

 

Is there a way to bypass that LDW that's on the rear view mirror or is theres a some kind of setting to do a farther distance to set so this doesn't gets triggared , does the heat effect it ?it's been low 90s here all week too

 

This van was in accident previously too light front pass side damage fender part that's why I'm checking over everything to see what else is missing, or who ever didt put everything back.also heres a picture of some green wire that's cut off right in front of a battery , when I had the bumper off i didn't see anything that it can connect to and all the wire housings looked factory wrapped in original tape like u see on the picture , is that a ground wire ? Or just a dummy wire?

 

I apologize for taking your time with this issue , don't want to take up your Sunday from u . I appreciate all the help ...I need to get this thing on the road

 

 

Quick update when I scanned with my obd scanner have 5 codes popped up 3 of P1659 and P2122 and P2127....can It be my accelerator gas pedal is malfunctionin?

 

Sorry it took so long to reply. Had an altercation with my step son about an hour ago and he broke my hand so had to go to the doctor. I will have to reply later
