Before you go spending a whole lot of money on a cat, you might want to swing into your local dealer and see if the PCM's calibration is up to date. Classification: EC10-014 Reference: NTB10-083 Date: July 8, 2010 2005 - 2006 ALTIMA WITH QR25DE ENGINE AND 50 STATE EMISSIONS; MIL ON WITH DTC P0420 APPLIED VEHICLE: 2005-2006 Altima (L31) APPLIED ENGINE: QR25DE* Engine Only * 50 State emission specification ONLY IF YOU CONFIRM:DTC P0420 (Catalyst System Efficiency Below Threshold) is stored in the ECM. ACTION: Determine if this bulletin applies by checking the ECM Part Number.^ You will do this by performing Step A in the SERVICE PROCEDURE. If this bulletin applies, reprogram the ECM and perform P0420 DTC Confirmation. ^ You will perform Step B and C in the SERVICE PROCEDURE. If this bulletin does not apply, refer back to ASIST and the Electronic Service Manual (ESM) for further diagnostic and repair information. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
