Diagnostic Procedures

WARNING: This page is about a different car, the 2003 Mazda B4000, 2003 Mazda B3000, and 2003 Mazda B2300. However, it is still accessible from the selected car via links, so may be relevant.

If QUICK TEST was not performed, go to QUICK TEST  under SELF-DIAGNOSTIC SYSTEM. If QUICK TEST was performed and any other DTC is present, go to appropriate trouble shooting for that DTC first. Refer to DIAGNOSTIC TROUBLE CODE DEFINITIONS  . If only DTC P0451 and/or P0461 are present, see INTERMITTENT  testing under SYSTEM TESTS.
