Mazda CX-5 Service & Repair Manual: Fuel System
Purpose, Outline
-
A multiple hole type fuel injector has been adopted which provides higher fuel injection accuracy for improved fuel efficiency and output.
-
Piston movement-compression by the 4-head cam inside the high pressure fuel pump heightens the fuel pressure, achieving improved fuel efficiency and output.

Fuel Gauge Sender Unit Inspection [2 Wd]
NOTE:
For the fuel gauge sender unit removal/installation, refer to the fuel pump
removal/installation because the fuel gauge sender unit is integrated with the
fuel pump..
1. Verify that the resistance at fuel gauge sender unit terminals D and C is
as indicated in the table ac ...
Rocking the Vehicle
WARNING
Do not spin the wheels at more than 56 km/h (35 mph), and do not allow anyone
to stand behind a wheel when pushing the vehicle: When the vehicle is stuck, spinning
the wheels at high speed is dangerous. The spinning tire could overheat and explode.
This could cause serious injuries.
