WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Diagnosis for this DTC will occur when engine coolant temperature is below 50 to 60°C (122 to 140°F). Therefore, it will be better to turn ignition switch ON (start engine) at the engine coolant temperature below 30°C (86°F) when starting DTC confirmation procedure.
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.

TESTING CONDITION:

Always perform the test at a temperature above -- 10°C (14°F).
Engine coolant temperature and EGR temperature must be verified in "DATA MONITOR" mode with CONSULT-II before starting DTC WORK SUPPORT test. If it is out of range below, the test cannot be conducted.
1. COOLAN TEMP/S :--10 to 50°C (14 to 122°F) ^*
2. EGR TEMP SEN :Less than 4.8V
If the values are out of the ranges indicated above, park the vehicle in a cool place and allow the engine temperature to stabilize. Do not attempt to reduce the engine coolant temperature or EGR temperature with a fan or means other than ambient air. Doing so may produce an inaccurate diagnostic result.

_* : Although CONSULT-II screen displays "-- 10 to 40°C (14 to 104°F)" as a range of engine coolant temperature, ignore it.
