Doubting the MAF. Performance is still very good. Maybe....better????

Could not join the reader to the OBDII port in the car. Very strange!

...and that's why i take my car to the dealership...but i've heard that the motronic system is fairly sophisticated and that there are many "layers" (for lack of a better term) that the deraler boxes can read and interpret that the handhelds cannot...in other word...you may get emissions system reading from your handheld where a dealer box might tellyou exactly where to go within that system...

...for $100 bucks, you didn't waste your money, at the very least, you have the direction of the fault when you walk into your dealer...

...goodluck on the magnitude!

Cheers,

Well I guess I was being too gentle with the plug in. Forced it in and viola. Codes were there to be read.
So the codes I got are.

P 1130
P 1128
P 0446
The first two are Porsche specific. The third has something to do with emmissions I think.

Any and all help is appreciated.

Thanks

Hi,

Here you go...

P1130 - Oxygen sensing adaptation, idle range, Cyl. 4-6

P1128 - Oxygen sensing adaptation, idle range, Cyl. 1-3

P0446 - EVAP Cannister Shut-off Valve (function) - Sort to ground, blow lower limit, lean mixture threshold

I believe these still point to the MAF sensor. Could also be O² Sensors given the mileage. Hope this helps...

Happy Motoring!... Jim'99

Since I got the $99.00 code reader to work, I figured that I'll clear the codes and see what could come up again.

I revved and idled in the garage this afternoon and the codes did not come back.

Could you post the Canadian Tire part number for that code reader?

And if you have time, could you either describe it or better yet, post a picture of it?

I'm in Asia right now but I'll get the P/N and post a pic once i get back to Canada
