2015 NISSAN SENTRA check engine light

Operation
The MIL will come on in one of two ways:● MIL 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 fuel-filler cap is loose or miss-
ing, 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.
● MIL 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 MIL 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 hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
