Engine Matrix supercharger in a Corolla?

Matrix supercharger in a Corolla?

I just found out something. I kept all the documentation and packaging from the supercharger I had installed in my 03 Corolla and noticed that on the box, it said that it was a 1.8L Matrix Supercharger. It even had the same part number for the Matrix s/c and not the Corolla.

So basically, I have the Matrix supercharger in my Corolla now and wondering if that is why my Check Engine light keep coming on this whole time. Maybe it is because the Matrix TRD ECU is conflicting with the stock Corolla ECU. Is that possible? If so, Toyota screwed up really bad. I'm going to call TRD USA directly during the week to double check on that. I'll be really frustrated if that's the problem. I have to get this resolved.

did you install the supercharger? Is there anytyhing loose?

There's nothing wrong with your package. The Matrix is officially a Corolla Matrix (as in the official name used in Toyota documents). Both vehicles use the same engines, same ECUs, same transmissions (with the exception of the AWD Corolla Matrix), and have the same unibody chassis. The only differences across S/C packages is auto./manual transmissions and 03/04 model year. If you have a 2004 model Corolla, the fuel mappings are different and the 03 piggyback unit will not function properly, leading to pre-detonation, which can only be corrected by acquring the 04 piggy back or swapping it for a UniChip and having it tuned for 04. If you are indeed on an 03, then there is something wrong with your installation, because even though TRD lists separate part #s for S/C packages for Corollas and Corolla Matrices, the only difference is in the title of the installation manuals.

I had Toyota install it for me, so I am a bit relieved that if anything happens, they have to loook at it. Ever since I had the supercharger installed, this kind of stuff never happened. It's an 03 and still new, so there is something wrong with the supercharger setup or the ECU is not responding properly. Maybe the car is running leaner, but the stock ECU is not making adjustments. I had the ECU reset like 3 times already by the dealer and still coming on.

If the supercharger for the 03 Matrix is ok and the same for the 03 Corolla, shouldn't their supercharger part number be the sameas the Corolla? Why still have separate part numbers?

Matrix and Corolla has the same part number 00602-17620-101 or 102..

as for you checking light,
1) do you have anything like Cold air intake installed? if so, try to put the stock air box back, and clean the MAF senser

2) have them check your 02 senser and your Cat-converter to see if they are ok.. (my check engine light went on right after my cat-conveter died)

3) what kind of gas are you using? 87, 89, or 91? and what brand are you using? my tech told me not to use ARCO and Shell, cuz it will cause my engine to ping and might cause the light to come on.

4) if non of the above is the problem... then you might want them to check/change the TRD Piggyback, the light went on might be due to the false wiring or bad piggyback. stock ECU souldn't have anything to do with your check light because TRD piggyback should have change the signal that came out of the stock ECU to the right seting.

As for my gas, I was running on 87 Octane but that was before the supercharger was put in. I had about half tank of the lower octane. So right after I had it installed, i went to Arco to put in some 91 octane. Arco is no good huh? What do you think about Chevron or anyother gas stations you recommend?

I don't have an intake kit anymore. I had to revert back to stock in order for the technicians to install the supercharger. I know that can't be the issue. I've only had the intake for about a week so there can't be that much oil on the MAF to cause any kind of abnormal damage. The TRD filter has oil too so it should be ok as long as I didn't over oil it.

Isn't it strange how an O2 sensor can fail so prematurely? After all, the car is only an 03. I wonder if there is a way to permanaently disable the Check engine light and clear it for good no matter what happends, besides disabling the light in the back. I hate that thing. It's always a big nuisance, especially when it comes time to have it smogged.

arco is nooooooo good, thats like the worst gas around, i was told to use 76 gas station by a TRD tech.. because it's better for boosted car and it actully fix some of the problems i had before.

how many miles do you have on your car?? i know my sister's Acura CL-S has about 30,000 miles and her O2 Sensor died and cause the Check engine light to came on..

also, i remember Toyota has a device that can plug into our ECU and find out why is the light coming on, they should be able to read the code and correct/disable it, i wonder why your dealer doesn't do that.

The TRD S/C part # is the same for both Corolla and Matrix. The difference in part #s is for the TRD piggy back unit. The fuel mappings of the 2004 Corollas are different than 2003. This has been a big headache for hooolala since the 03 TRD piggy back would not work properly and caused pre-detonation. He's since switched out to a UniChip and had it retuned for 04 fuel mappings.

TRD has thus decided to separate, very clearly, each model year, vehicle model, and transmission type to prevent any confusion over parts. In truth however, the 03 piggy back units are the same (with the exception of manual/auto tranny).

EDIT: You can get the OBD-II compliant ECU reader for about $1,000 USD. It'll give you the error code and you can match that up with an online database of error codes.

or pop in to most any part shop and use theirs, free.

Re: Matrix supercharger in a Corolla?

Tom,

Like everyone here has said, Matrix-Corolla S/C are the same. Mine said the same thing. Arco is also the dirtiest gas when you compare "dirt" ppm. To give you an example, about 2 years ago, Arco had 2000 ppm, while Chevron and Mobil were in the low hundreds. I've been using Shell and haven't had problems. One thing though I do remember in the Carson install, there was a hose loose under the engine cover that came out of the throttle body. I noticed it only because I was anal and checked the installation instructions to make sure everything was in place. Maybe a hose is misplaced?
