Need help with engine error codes on 99 boxster
I have the following engine error P-codes:
P0102 (Mass air flow sensor, short to ground/below lower limit/ lean mixture threshold)
P1124 (fuel pump relay output stage, short to ground/below lower limit/lean mixture)
P1126 (oxygen sensing adaptation, lower load range, cyl. 1-3, short to B+/above upper limit/ rich mixture threshold.)
I would be immensely grateful to anyone who has ideas on where to start. Thank you soooo much!
Colby
