Post DP install codes, would like some feedback to ensure I'm on the right track

thatoneguy... · 07-13-2016, 03:52 PM

Hey all! Just got done installing my 2nd hand AR Design catted DPs this past weekend, and loving it so far. Yesterday, after driving for a bit with a few hard pulls (I think I really surprised that Porsche Targa driver, he wasn't expecting me to keep up with him!), the SES light came on with several codes. I hadn't set up autoclear on the JB4 so I could see if anything was amiss, so I was kind of expecting this. Here's what I've got:

2D2E
29F4
29F5
2C7E
2C6A

The first three I'm not worried about. The first one is fairly common, from my understanding and just a part of living with the JB4. The second and third are the catalytic converter codes, which will be handled by JB4's autoclearing function. The last two have me puzzled; I'm not sure if the O2 sensors are bad, or if I just got them mixed up during install. I read on e90post that both codes are a result of reversing the sensors, but I'm fairly sure I have them on the right way.

Any help would be great! As always, you guys are awesome!

EDIT: Should point out that car runs fine, nothing out of the ordinary from what I can tell (except for a slight smell, might have a minor leak at the gasket. I'll have to take a closer peek.

That stinks... I doubt the code is from reversing the sensors. The only difference i know of between the sensors is the wire length. One is short one is long.

Yeah those a are O2 sensor codes. You ether swapped them during the reinstall or damaged them. In my case when I removed my dpfix, I reversed the wires in the ECU compartment. Hope you can figure it out!

Are there any consequences in running them reversed?

I cleared the codes and so far have no new ones... I don't think I turned autoclear on

Sorry, I should have told you to trouble shoot first, since you have cleared them, see if the codes come back after a couple hundred KM to confirm. If they are swapped it isn't good for the system, you'll be running too lean or rich.

Okay. Think I could just switch the connectors they're plugged into, or are they entirely different assemblies?

litebulb · 07-17-2016, 12:31 AM

I wouldn't, they aren't separate connectors, you have to take one apart and it's wire 19/20.

Gotcha, I was hoping for an easy fix. Ah well, back under the car we go!

Let us know how it goes

I swapped the rear sensors when I went in and replaced a leaky gasket. So far, all's good! Definitely runs smoother and no SES lights or CELs, autoclear is off.

It was DEFINITELY easier the second time!
