Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

You can get around using the "special tool", which is a Porsche specific pin out box, but it is going to be a lot more time consuming as you would need a digital multimeter and the car's wiring diagrams to test the circuits.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I got a check engine light yesterday on my 1999 C2 and as it turns out, my durametric (clone) cable just gives me a red light so I can't connect it. But I picked up a code reader from Harbor Freight today. I get the following codes: P0102 P0446 Any idea on where to start? Anyone experienced these? The car starts and runs like it always did leave car or drive car while figuring this out?

First of all, when asking this type of question, always include the year and model of the car as it can make a difference in which is the correct answer. Assuming it is a 1999 car: P0102 - Mass airflow sensor below lower limit; likely faults: break in the wiring, short to ground. P0446 - EVAP canister shut off valve below limit; likely faults: purge air line blocked, flow blockage in the EVAP canister

POST 3 / ORIGINAL POSTEROriginal post

Hi, thanks. Yes, 1999 C2. I see the codes, and I found what the OBD manual says about it. Is there any thing I should check before that? Is this commonly caused by something? Someone also asked me if I had occasional trouble starting the car, and yes I do. If takes a few extra cranks to start it, I think. And a few times I tried starting it but it didn't, I had to wait a minute and try again. Here's the OBD manual steps. Just start going through them then? I don't have the Special Tool, can I get around not using it? P0102 P0446

POST 5 / ORIGINAL POSTEROriginal post

I cleaned the MAF. The air filter and inside of the air box was fairly "dirty" for a filter I replaced in July. Cleared the codes. Let's see how that goes. Live OBD data.

This is a source reference. Confirm exact model applicability in the original material.
