When to not do idle and volume relearn?
Do not perform the relearn if the service engine soon light is on and codes related to the mass airflow sensor, manifold absolute pressure, or incorrect idle speed are found. If everything is in order, we can begin. First, bring the engine to normal operating temperature, 160-203°F or 70-95°C.
What is the idle relearn procedure for a Nissan?
Once the throttle body has been cleaned, reinstall on the intake manifold using a new gasket and proper torqueing procedures. Then perform an idle relearn procedure. This is a three step process; Accelerator pedal released learning, then a throttle valve closed position relearning, and finally an idle air volume learning step.
