CEL fix from Scoobysport

corallo99 · 10-02-2002, 10:41 PM

I have a US spec 2002 WRX with no cats. I wired up the CEL fix from scoobysport and the CEL light is still on. Is there anything i did wrong, I followed the directions precisely. Anybody have an experience with this product?

Davenow · 10-02-2002, 10:46 PM

did you reset the ECU?

corallo99 · 10-02-2002, 11:53 PM

Well i disconnected the battery and totally unpluged the ecu cause i was cutting wires, so yeah it was reset.

STi_Pete · 10-03-2002, 01:59 AM

How long did you diconnect it for......

Easiest way is, Disconnect the NEG terminal, depress the brake for about 30-60 seconds. Reattach the NEG terminal and BAM your ECU has been reset.

Then if your fix didn't work it IIRC I have read it takes 4 full operating cycles with the same malfunction for the CEL to come on. GOOD LUCK

corallo99 · 10-04-2002, 02:01 AM

It was disconnected for like 45 minutes. I then plugged it all back in and it came on like 150 miles later. Does anybody actually have any expeirence with this product and the wiring. Thanks for the help but i dont think its a matter of disconnectig the battery.

rlavalle · 10-04-2002, 02:57 AM

I had a CEL after swapping out my exhaust for a ScoobySport system too... but it turned out to be a CEL from false EGT readings. Later, the EGT sensor died and the car wouldn't run until the sensor was unplugged.

You might try disconnecting your EGT sensor (plug is under the plastic the black plastic cover in front of the passenger side strut tower).

Unless you're positive that the CEL is a cat efficiancy code then I would get the code pulled just to make sure it's not something else setting it off.

rlavalle · 10-04-2002, 12:02 PM

Oh yeah... you'll need to add a resister to the plug going to the wiring harness to eliminate the EGT CEL.

Do a search to find the correct value.

SilverBoosted · 10-04-2002, 12:43 PM

In corallo99s defence we pulled his codes with a subaru scanner before the scoobysport mod . The only code in the system was a low cat efficiancy code. No other codes were present. His EGT sensor was reinstalled into the PDE uppipe and has given no codes so far. I doubt hes got a new code since the scoobysport mod... Poss the scoobysport part is defective???

corallo99 · 10-04-2002, 06:04 PM

Im pretty sure that it is the cat code. I did pull the code before the CEL mod and it was the 0420 code. So i doubt that by coincidence that i have a new code all of a sudden. I never had any other codes. The instructions that came were for RHD cars and did have the changes written for LHD cars but the diagrams of the harnesses were a little differant.

Seems like few people actually have this product. Is there anybody out there that does have it???????

18431 · 10-05-2002, 11:39 AM

The Scoobysport fix followed by a CEL has been addressed elsewhere but you will need to search. The Scoobysport fixes the 0420 code but has for some people resulted in another code, which I cannot remember offhand. On my car, this secondary code may be related to the uppipe leak I have on and off, though. I'm so used to looking at CELS I forgot to reset the ECU this week after fixing my leak.

rlavalle · 10-05-2002, 12:42 PM

I should have mentioned in my post that I have the ScoobySport CEL mod as well and it's working like a charm.

After I installed the PDE Up-pipe and ScoobySport Turbo-back, I got a CEL. I added the ScoobySport CEL eliminator, but got a CEL back after 150 miles. I didn't read the code, so am not sure which it was.

Anyway, the car went into limp-nowhere mode at a track day and was later diagnosed as having an EGT sensor failure.

As I understand it, when you add an up-pipe, the EGT sensor gets the full blast of exhaust instead of being somewhat protected by the stock up-pipe's cat. So it often fails. This is what happened to me.

Reset your computer, then read the CEL code when it returns. Or install the 79 cent resister after unplugging the EGT sensor.

It's not a coincidence to get an EGT CEL after an up-pipe install along with the Cat efficiency CEL... it's cause & effect. Lack of Cat action triggers the Cat efficiency CEL while a failing EGT sensor triggers the EGT CEL.

Good luck,
Russ

corallo99 · 10-06-2002, 01:30 AM

Russ, thanks a lot dude. That made a lot more sense. I will now definately get the code pulled.

So as far as the egt sensor failing when people do the relocation of it does that make it fail also? People have also said that removing the cat lowers EGT's. What actually makes it fail, the velocity of the air or the increase in temp (if there is an increase) Thanks dude.

Oh and i had no cats for like 3 months with the CEL cause of the backorder on the cel fixes. And when i did have the code read it was only the 0420.

rlavalle · 10-06-2002, 02:13 AM

Hi corallo99,

Not sure what exactly causes the sensor to fail. The guy who diagnosed my problem (Sean from Wentworth Subaru in Portland) said that this happens often with catless up-pipes.

Good luck,
Russ

corallo99 · 10-08-2002, 11:49 PM

Ok. Went to Subaru today and I had the code pulled. It is nt the 0420 code it is the 0136 code for a bad sensor the full thing is bank 1 sensor 2. So what do I do now? Is that code just saying the sensor is bad? I doubt the sensor went bad obviously it has to be related to the no cats or the CEL fix.

lstepnio · 10-09-2002, 12:10 AM

If I recall correctly some folks have reported the same problem using the Scoobysport CEL fix mystery box a little while ago. You might want to take a look at this long thread and see what you come up with in regards to details: http://forums.nasioc.com/forums/show...ysport+cel+fix

Have you considered keeping things simple and using the $20.00 Pony Express CEL fix?
http://www.ponyexpressperformance.co...liminator.html

A bunch of WRX folks seem to be really happy with the Pony Express CEL fix and I have yet to see anyone reporting any ill effects.

corallo99 · 10-09-2002, 12:50 AM

That post was interesting but didnt really help me find out how to fix the 0136 code that I have.

lstepnio · 10-09-2002, 01:08 AM

My advice based on personal experience and information supporting my experiences documented in the thread I mentioned before I would suggest picking up the Pony Express CEL fix and removing the Scoobysport mystery CEL fix box. I'll be willing to bet you won't get the 0136 code or the 0420 with the Pony Express fix. You could also consider just removing the Scoobysport fix and see you start tripping a 0420 again w/o the 0136 and if that's the case it you basicly proved the Scoobysport fix is causing the 0136 CEL.

You did read the whole thread, right? It's like 5 pages long and does not start to get meaty until you get to page 2 or 3.

Let us know what you decide and how it works out. Good luck!

corallo99 · 10-09-2002, 01:22 AM

yeah i read all of it. Im pretty sure it is the black box causing the the 0136 code. I just wanted the best of both worlds with no CEL's at all. I might go with the pony express or the ILP fix then.

Before the CEL box fix i only had the 0420 and now i have the 0136 also, so it must be the box causing it. I just dont feel like pulling the box to see that the code is just the 0420 code again.

Thnaks for all the help.

lstepnio · 10-09-2002, 01:32 AM

I'm curious when you say "the best of both worlds" what do you mean? I have yet to see any data supporting the unpopular opinion that the rear O2 sensor is used for anything other than monitoring the cats.

It would seem to me that if there was any truth to the opinion that the rear O2 was used to adjust fuel there would be data hinting towards it if not clearly supporting it.

I don't think the Scoobysport fix is doing anything special and until we see some data hinting otherwise I don't think you should worry yourself.

ILP Performance.com · 10-09-2002, 01:39 AM

yes our fix is availble in wire in and plug in.

wire in is currently selling for $19.00
plug in is 57.75 (comes complete with the harness to replace the stock unit)

guarenteed 100% p0420 free operation

Thanks for your time

Austin · 10-09-2002, 02:28 AM

As I said in your PM, your 0136 code is due to the scoobysport fix-it box. You can send it back to scoobysport for another fix-it box, but you may get the same error code again.

When I was running on the stock ECU, my CEL fix was very simple - a piece of black electrical tape over the Check Engine light.

MudBoogers · 10-09-2002, 08:56 AM

i'm in the exact same boat as you wrt SS CEL fix black box potentially being the cause of the P0136 CEL code... I have sent at least three or four emails to Ken C. and NEVER received even one response on this, which is why I think I'll go w/ponyexpress or ILP fix, as well, and hopefully resolve this annoyance...

WHTWRX · 10-09-2002, 01:41 PM

So if catless up-pipes like to burn out your EGT sensor, is this a really bad thing? What happens to the car if the sensor fails? I just added a PDE pipe, I need to know what to do at this point. I do have a cel, and I'll get the code pulled soon to see what it is.

corallo99 · 10-09-2002, 10:30 PM

lstepnio, when i say the best of both worlds i mean no 0420 code and no 0136 code. At this point i might just pull the ****ing bulb form the check engine light. Anyway i guess the next step is to talk to ilp performance.

WHTWRX as of now the EGT sensor is fine. We are mostly talking baout the second o2 sensor.

Thanks everyone
