Hey Everyone,

I recently purchased a new 2007 s2000...

Yesterday I made some modifications to the car and now my CEL is on constantly.

I added AEM Prototype CAI, Megan Headers, Megan Test Pipe, T1R Sparrow 70mm Dual Exhaust, 4.57R Richmond Gears.


I went in and had the codes pulled but the guy that pulled the codes didn't speak the best of English =/ .... So, I've looked the codes up on the Forums but I don't know what it means really or how to fix it =P

P0113 - Intake air temperature circuit high input
P0108 - Map Sensor Voltage High
P0420 - Converter Efficiency

I know that P0420 is because I have no cat on the car....
I've tried the spark plug foul adapter jimmy rig but lol couldn't get it to work.
I'm working on getting an o2 simulator now.

Can any of you tell me more about p0113 & p0108 like what exactly they are caused by and how I can fix them and get my CEL off please?

Thanks,

Adam

 

You probably disconnected the sensor on the intake to install the AEM, thats what the P0113 is ... You just need to clear that one.

The P0113 and P0108 could have been caused by unplugging the sensors with the key on.

The P0420 is from the test pipe.

Reinstalling the Catalytic converter seems to be a pretty good fix for a 06 and later car.

 

Did you install the spark plug anti-fouler rig properly? you install 2:

The one that goes into the TP is not modified. The second one, that goes into the one that is already in the TP, has to be drilled out to make sure the hole can accomodate the tip of O2 sensor, since the tip of the O2 sensor might be too long for the anti-fouler:

|=| is the hexagonal part
=== shaft, and - is the tip with the little hole.

O2 sensor -> |=|===- -> |=|===- -> TestPipe O2 Bung

I installed it just as you said.

I'm wondering if I may need to reset my ECU?

On the page with the instructions of how to make the spark plug anti-fouler o2 simulator it said that if my CEL had not previously been on that I did NOT need to reset my ECU.

I'm wondering if that could have been a piece of miss information?

The majority of people that said that this fix worked were people that already had a test pipe installed and reset there ECU.

Do you think that would be the next option for me to try?

I also noticed that a few people said they drilled holes in both spark plug anti-fouler and that that worked for them.

If I keep having a problem with just one drilled out I may try that out.

Thank you guys for the help.

 

No, don't drill out the second one. It needs that small hole in it, that way less exhaust gas gets to the sensor. That way the sensor thinks it's getting less hydrocarbon emissions compared to the one in front of it, just like it would if you still had your cat on. The anti-foulers need to go on the secondary, the one closer to tail-end of the car sensor.

Make sure you got your radio security code.

Then reset the ECU: pull off the neg batt cable.

Go inside, remove the side fuse kickpanel.

remove the 7.5 'backup' fuse, stick it back in, put the cover on, put batt cable on, close hood.

Go for a drive. At this point you should have no CEL.

If you do, it's a problem that apparently still hasn't been resolved. Pull the code(s) again.

 

I went and had my ECU flashed....

No CEL's anymore.... =

=D
