Inspection
1. | Connect the GDS on the Data Link Connector (DLC).
2. | Measure the output voltage of the RPS at idle and various engine speed.
Condition | Output Voltage (V)
Idle | Approx. 1.2
1,500 rpm | 2.2 ~ 2.5
6,300 rpm | Approx. 3.0
Removal
1. | Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2. | Release the residual pressure in fuel line (Refer to “Release Residual Pressure in Fuel Line” in this group).
When removing the fuel pump relay, a Diagnostic Trouble Code (DTC) may occur. Delete the code with the GDS after completion of “Release Residual Pressure in Fuel Line” work.
3. | Remove the intake manifold (Refer to “Intake And Exhaust System” in EM group).
4. | Disconnect the rail pressure sensor connector (A), and then remove the sensor (B) from the delivery pipe.
Installation
• | Install the component with the specified torques.
• | Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.
1. | Installation is reverse of removal.
Rail Pressure Sensor Installation: 29.4 ~ 34.3 N.m (3.0 ~ 3.5 kgf.m, 21.7 ~ 25.3 lb-ft)
