Returnless Type
1. OVERVIEW
The fuel system is a returnless type that the fuel pressure regulator is mounted inside the fuel tank.
The engine ECU controls the fuel injection in each injector electronically.
According to the engine loads, the engine ECU draws or cuts off the evaporated gas in canister into the
combustion chamber. The fuel system consists of fuel tank, fuel lines, fuel pump and fuel pressure
regulator.

4. INPUT/OUTPUT DEVICES
The engine ECU calculates the accelerator pedal based on the input signals from various sensors, and
controls the overall operation of the vehicle.
The ECU receives the signals from various sensor through data line, and performs effective airfuel ratio
control based on these signals.

1. OVERVIEW
The ignition system is to supply high voltage generated from the ignition coil to the spark plug. The
G20DF engine is equipped with the independent type direct ignition system that the ignition coil is
installed in each cylinder.
The basic ignition timing in each cylinder is determined by the signals from camshaft position sensor and
crankshaft position sensor.
This ignition system controls the electronic ignition timing received from the engine ECU. To control the
ignition timing precisely, the ECU use the information below:
Engine load
Coolant temperature
Intake air temperature
Engine rpm
Camshaft position sensor (CPS)
Crankshaft position sensor (CKS) -
-
-
-
-
-
If the signal from the camshaft position sensor is not delivered to the engine ECU, the ignition coil and
fuel system cannot be operated.
