Turn the ignition switch on and check that the fuel pump operates for a few seconds.
If the fuel pump motor does not make operating sound, inspect the fuel pump circuit connections or inspect the fuel pump relay and to sensor. Refer to “fuel pump relay inspection” and “dtc “c23” (p1651- h/l): to sensor circuit malfunction” in section 1a .
If the fuel pump relay, to sensor and fuel pump circuit connections are ok, the fuel pump may be faulty, replace the fuel pump with a new one. Refer to “fuel pump disassembly and assembly” .
Fuel pressure inspection
Fuel discharge amount inspectionAir bleeding from brake fluid circuit
Air trapped in the brake fluid circuit acts like a cushion to
absorb a large proportion of the pressure developed by
the master cylinder and thus interferes with the full
braking performance of the brake caliper. The presence
of air is indicated by “sponginess” of the brake lever and
also by la ...

Exhaust control system operation
The excs is operated by the signal supplied from the ecm. The open/close
operation of the excv is performed by
the excva which is controlled by the ecm by changing the current direction of
the actuator motor. The position
sensor (incorporated in the excva) detects the excva movement by measuri ...
