Nissan Altima: Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or blinks while the engine is running, it may indicate a potential emission control malfunction.
The Malfunction Indicator Light may also come on steady if the fuel-filler cap is loose or missing, or if the vehicle runs out of fuel. Check to make sure the fuel-filler cap is installed and closed tightly, and that the vehicle has at least 3 gallons (11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20 seconds and then blinks for 10 seconds when the engine is not running, it indicates that the vehicle is not ready for an emission control system inspection/maintenance test. See “Readiness for inspection/maintenance (I/M) test” in the “Technical and consumer information” section of this manual.
Operation
The Malfunction Indicator Light will come on in one of two ways:
● Malfunction Indicator Light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap if
the LOOSE FUEL CAP warning appears in
the vehicle information display. If the fuelfiller
cap is loose or missing, tighten or install
the cap and continue to drive the vehicle.
The light should turn off after a
few
driving trips. If the
light does
not turn
off after a few driving trips, have the vehicle
inspected by a NISSAN dealer. You do not
need to have your vehicle towed to the
dealer.
● Malfunction Indicator Light blinking — An engine misfire has been detected which may damage the emission control system. To reduce or avoid emission control system damage:
– do not drive at speeds above 45 MPH
(72 km/h).
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo
being hauled or towed.
The Malfunction Indicator Light may stop blinking and come on steady. Have the vehicle inspected by a NISSAN dealer. You do not need to have your vehicle towed to the dealer.
CAUTION
Continued vehicle operation without having the emission control system checked and repaired as necessary could lead to poor driveability, reduced fuel economy, and possible damage to the emission control system.
