Check engine light is on, Help
 

My wifes 2002 Boxster has 75k on the odometer and this morning the check engine light came on. The car is running fine and has had a recent service (oil,filters,etc) any idea? Thanks lennySmileWavy

Without reading the code(s), it is impossible to offer any assistance………….

JFP, I did purchase an odm reader but have not used it at all yet. When I get home I will connect it, what should I be looking for and how to I decifer the codes?

The codes will begin with a "P", followed by four digits; P0306 for example is the code for a misfire in cylinder #6. Remember that there are often multiple codes and that the digits are very specific, so read them carefully and write them down.

You will find some of them quickly by doing a search here or at other Porsche specific sites. Let us know what you find……….

CEL solid, read the codes and post them.

Blinking, flatbed to an expert Porsche mechanic.

Check light is solid and reads P1130.

Also it should be noted I put one of those blue no oil reusable after market filter in about two months ago. Could this have caused the problem?

P1130 indicates that the O2 sensor on the even numbered cylinder bank (4-6) has reached its enrichment limit. This is typically caused by air leaks in the intake system, low fuel pressure or volume, injector problems or similar fuel delivery issues.

I’d start by looking at the intake system as you just changed the filter………….

Thanks Jfp, I will start tomorrow and post the out come. On my way home from work I stopped at Champion Porsche and picked up a new air filter and will replace it either way. Clean the MAF and maybe the Pelum. I once had a KN oil type filter that gooed up the MAF, you would think I would learn.

While you are changing the filter, check all the intake connections and vacuum lines, odds are you disturbed something and now have an air leak..............

Ok, changed the air filter, removed MAF sensor and cleaned with CRC maf cleaner, checked for vac. leaks, none found, checked boots for cracks. Put all back together and reset my engine light. Light is off but too early to tell. Car is running great, we shall see!

Yes, I have a feeling it might have been related to that air filter. I personally like to stick with the stock ones. The reusable ones can dirty up the MAF if you're not very careful.
