The ECU rely on the MAF usually because it's a more reliable way to manage an engine, but it's not the only way it can manage it, that's why you see no change when you disconnect it.

Is this possible, or is it because it's just an amazingly fun car to drive and subconsciously I think it's running better?

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi everyone, Over the last couple days I've been reviewing a number of forums and am having a tough time finding a lot of information on P0103 code. There is a lot out there about P0102 mentioning to replace the MAF, however a lot of the information on the P0103 mentioned to reseat the connector, run the car without the MAF connected, etc. In doing the above, people mention that when the MAF is disconnected their Boxster runs really rough or not at all. When I disconnected the MAF and ran my Boxster, there was no difference in how it was running. Is this normal? My question is, if my Boxster runs the same with our without the MAF connected is the problem the MAF, or something else? Thanks in advance...

POST 2Original post

If your boxster runs the same without MAF it's dead (the MAF). The ECU rely on the MAF usually because it's a more reliable way to manage an engine, but it's not the only way it can manage it, that's why you see no change when you disconnect it. It's not relying on it anymore because it is not reading anything from it. Not like when you get P1128 and P1130 codes, which mean that the MAF, MAP and O2 sensors reading aren't what they should be.

POST 3 / ORIGINAL POSTEROriginal post

Thanks...ordering a new MAF now.

POST 5 / ORIGINAL POSTEROriginal post

I did what I could and they looked pretty clean. Replaced it last night cleared the code, and ran t for a bit. Check engine light has not come back on, but I haven't really taken it out for a good run, plan to do that this weekend. Thanks

POST 6 / ORIGINAL POSTEROriginal post

quick update...replaced the MAF, and everything seems to be working fine now, if not better. The car seems more responsive. Is this possible, or is it because it's just an amazingly fun car to drive and subconsciously I think it's running better? :-)
