2002-2003 Altima And Sentra Qr25De Engine Exhaust Pipe Hanger Pin And Pre-Catalyst
download
Note: for 2003 and 2004 applied vehicles: when you perform procedure c (ecm reprogramming), go to ntb06-051a for reprogramming information. You will still need to perform all other parts of this bulletin on 2003 and 2004 applied vehicles. Introduction nissan has determined that some 2002-2003 model year altima and 2002-2004 model year sentra vehicles equipped with the 2.5 liter engine have defects that relate to motor vehicle safety. For 2002-2003 model year altimas, there is a possibility that the exhaust pipe hanger pin may catch debris from the road that could be ignited by contact with the catalytic converter and cause a fire. In addition, for 2002-2003 model year altimas and 2002-2004 model year sentras, there is a possibility that certain engine operating conditions may cause damage to the pre-catalyst. Material from inside a damaged pre-catalyst could enter the engine and result in increased oil consumption. If the engine oil level is not checked on a periodic basis and drops below the low level, and the driver continues to operate the vehicle ignoring noticeable engine noise, engine damage may occur which could result in a fire.

Identification number
nissan has assigned identification number
r3007/r3014/r3015/r3016/r3017 to this campaign. These numbers must
appear on all communications and documentation of any nature dealing
with this campaign. Overview of repair exhaust pipe hanger pin: • the exhaust pipe hanger pin is shortened on 2002-03 altima,
except those that were already repaired. This repair is not necessary
on sentra vehicles. (this repair may be needed only if the pnc code is
r3007.) ecm reprogramming / pre-catalyst / exhaust heat shields:
• ecm reprogramming is required to prevent future damage to the
pre-catalyst. A special reprogramming card is available that contains
ecm reprogramming data for all models/engine/transmission configurations
affected by this campaign. • the exhaust pre-catalyst will be tested to determine if the pre-catalyst needs to be replaced. • the exhaust
pre-catalyst will be inspected to determine if more extensive repairs
are needed, that, for a limited number of vehicles, may include engine replacement. • installation of new heat shields on the exhaust system
for vehicles with pnc code r3007, r3014 and r3016. Note: for vehicles
with pnc code r3015 and r3017 new heat shields are not required. Do not
use a visual inspection to determine the need for new heat shields, use
the pnc code. Use the “repair flow chart” in the service procedure to
determine the complete repair procedures for a specific vehicle.
