I have a tech problem I desperately need help with!

I have a 2007 Acura RDX with technology package.

At first just had check emissions and sh-AWD so I changed knock sensor with cheap sensor. Lights went away for two days came right back. Drives good slight knock on acceleration tried adding octane booster.

Then was getting above with additional abs and brake system lights. At that time car would barely move and If I put in park knob would not move. If I restart car all is good and runs well until those two lights randomly come back on.

My mechanic had me take to dealership to computer diagnose problem. They said I needed a new wiring harness which my mechanic just installed. Still have exact same problem. I have reset codes they come right back. The lights and codes are as follows.

Dash Lights
First check Emission System then check SH-AWD System. Then ABS and brake system lights at same time.

Codes
A01 All- Wheel Drive: 77 @
A02 Airbag System: : @811
A03 Emissions System: P035@
A04 Vehicle Stability: 83 @
A05 Throttle System: P3138@4

Anybody have any ideas how to fix this we are at a loss?

 

I'm really not sure what's wrong.


I suppose you could replace the harness, but that would just be throwing parts at it and hoping it fiexes the problem!

 

Those codes look weird to me; I've never seen an OBD code with the @ symbol in it.

Do you have your own code reader or could you go to Autozone to verify?

 

This might sound weird but check your fuses. Inside the cabin and under the hood, I had a car that stalled on me, temp gauge went all the way up car just didn't want to start. A 10a fuse in the cabin blew, replaced car ran and acted fine. Give it a shot just takes like 20-30 minutes to pull the fuses wouldn't hurt.
