Hi

I have poor fuel economy and performance with my Mazda MX5. It is a 2001 Mk2. It is too old to have OBDII DLC connector sadly. However, it an underbonnet Diagnostics socket. Using an LED, I have uncovered the following fault codes: 11, 13, 14, and 15. I have a list of Mk1 codes but can't find the Mk 2 codes anywhere. Can anybody help? Cross-matching the codes to the Mk1 list gives the following results:

11 Code does not exist

13 Code does not exist

14 Pressure sensor fault

15 Oxygen sensor fault

Can anyone help with codes 11 and 13?

Thanks, Peter
