Hi all!
A mechanic told me (for free) that my 00 Mirage has these 2 codes:
Quote:
P0100 OBD-II Trouble Code
Mass Air Flow (MAF) Circuit Malfunction
A code P0100 may mean that one or more of the following has happened:
The MAF may be disconnected, or a wiring connection may be bad
The MAF sensor may be faulty
|
Quote:
P0421 OBD-II Trouble Code
Warm Up Catalyst Efficiency Below Threshold (Bank 1)
A code P0421 may mean that one or more of the following has happened:
The catalytic converter is no longer functioning properly
An oxygen sensor is not reading (functioning) properly
A sparkplug is fouled up
|
Do these 2 codes in combination mean the catalytic convertor will probably need replacement?
Thanks for any insight
