Yes, throttle was unresponsive because the DME goes into limp mode when it's getting conflicting input from sensors, i.e. air getting in around the maf, or air leaking out after the turbos. I figured a lot my codes were caused by the after effects of the air leak.

 

Guys take your y pipe and clean your throttle body out with throttle cleaner its oily which causes this issue. I had this same issue and codes. Make sure you do the throttle adaption after ohh take off the electrical plug on the throttle body before cleaning it and moving it.

 

A post MAF leak could make some sense, the airflow doesn't match expectations and it thinks the position is wrong, easy enough to check. I'd still suspect the throttle first as e-throttle seem to be pretty picky.

 

Those codes are straight to the throttle. Computer can't pass the spring test.

 

E-throttle does it mean the throttle position sensor?

 

 

My 2000 Boxster roadster with 2.7 is in limp mode. I have a P1502 code

My generic scanner say is it is "fuel pump relay end stage.
I have read where it is a "jacking spring"
Clear the code, the engine smooths out and runs correctly
I have removed the throttle body, cleaned it and reinstalled. Problem remains
I was about ready to order another throttle body and thought I would ask for help from group.

is the throttle body the problem?
If not, where should I look?

If the TB is bad, is it OK to try a used one or an aftermarket TB

Thank you

Thank everyone for the posts

I have read everyone's posts and am a bit confused which discussion topics pertain to my Boxster. MY generic scanner only shows code P1502

I cleaned the throttle body a few days ago. It was not very dirty before it was cleaned. I also cleaned the MAF

I will check for air leaks tomorrow.

Is a dirty fuel filter a possible cause?
