Rail Pressure Sensor (RPS) is installed on the delivery pipe
and measures the instantaneous fuel pressure in the delivery pipe. The
sensing element (Semiconductor element) built in the sensor converts the
pressure to voltage signal. By using this signal, the ECM can control
correct injection amount and timing and adjusts the fuel pressure with
the fuel pressure regulator valve if the target pressure and the actual
pressure calculated by the RPS output signal are different.
Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the HO2S connector.
3.
Measure resistance between the HO2S terminals 3 and 4.
4.
Check that the resistance is within the speci ...
Description
Continuous Variable Valve Timing (CVVT) system advances or
retards the valve timing of the intake and exhaust valve in accordance
with the ECM control signal which is calculated by the engine speed and
load.
By controlling CVVT, the valve over-lap or under-lap occurs,
which m ...
