The Problem: https://youtu.be/StEaqE3SFeo
The initial problem code was: P1297 No Change in MAP sensor from start to run.
What I have done so far: Replaced map sensor, it did nothing, anon mentioned to poke around with a multi-meter, so I did, using a haynes manual as reference, I found out that the Voltage supply is showing 0.01 to 0.02 volts The sensor ground is getting 5.00.
Also I'm getting a new code now P0122: Check for breaks, chafing, loose or disconnected wiring
Throttle/Pedal Position Sensor A Circuit Low Input.
The P1297 No Change in MAP sensor code is not showing up anymore?
What do I do next anons?????
Your wiring is all shit buy a new wiring harness and get rid of the trashed crap.

Really negro? You have put more effort into making this car run than Dodge did when they R&D the fucking thing. Just get another neon and use this one for parts ffs.

Take it easy on me anon, I'm learning :(
I will earn the /o/ badge of honor soon you'll see.
>>17217503
That sounds like a big head ache.
>>17217530
Did you download the factory service manual?
Did you ask around if a shop has a DRB-III they can run on the car?
When you have done both of those things I'm sure you'll find your answer.

Electrical gremlins are a bad way to learn m8.

On a car that old my guess is that you have the short in the wiring or the computer is fucked. Id lean toward a short.
You are going to have to inspect every fucking inch of wiring. Friend of mine had a Neon. The engine would shudder while backing up and only in reverse. Turned out it was a spark plug wire that was shorting out....only in reverse...in a brand new neon.

Thanks. How is a bad wire repaired? is there a method I can google? Any way to easily find a bad wire? Tips or anything appreciated.
>>17217596

Oh god just watched a youtube video on how to do this. This is going to be a nightmare.
replacing the entire harness sounds unessicary.
Go to your local electrician and offer to help him for a discount its what i do.

Sounds like the entire harness is going to have to come off though to inspect it properly. I couldn't find any cuts or faulty wires just by looking at it, I suspect it's behind the previous electrical tape or insulation that it has on now.
>>17218204
yikes.
Just get a better harness off a wreck, get a mate or local mechanic to help
>>17218210
Why yikes? The electrical tape a bad sign?
>>17218227
yeah, pics?
>>17218232
Yea but not very good. It's actually a video screen grab. one sec let me upload.
>>17218232
Sorry, it's not very good, but there is tape everywhere like this.
>>17218232
Heres some tape too on the mapsensor connector harness.
>>17218232
Still there?
>>17218292
yeah bud still here
Looks stock.
Hmm, seems in on condition, maybe check the ecu itself
>>17218373
Yea damn eh, I was thinking what a bitch it would be to mess with the wiring and to find out in the end its the computer.
>>17218373
I heard you can reset an ECU by just unplugging the battery, do you think that might be worth a try?
>>17218410
might only be a temp fix.
leave it disconnected for 5-10 minutes just to make sure.
IF not post back keep troubleshooting
>>17218424
But at least we might find the culprit that way right? Well I'll have to try it out tomorrow, it's midnight now. Thanks for your help.
>>17218444
