Fuel Pressure Sensor
WARNING:
Observe the following precautions when working on fuel systems: No sparks, open flames or smoking. Avoid inhaling and swallowing fuel. Avoid eye and skin contact with fuel. Pour fuels only into suitable and appropriately marked containers. Wear protective clothing. Failure to observe these precautions may result in fire, explosion, property damage, and serious or fatal injury.
WARNING:
High-pressure fuel lines deliver fuel under extreme pressure from the injection pump to the injectors. This maybe as high as 1350 bar (19,580 psi). Use extreme caution when inspecting for high-pressure fuel leaks. Inspect high-pressure fuel leaks with a sheet of cardboard. Wear safety goggles and adequate protective clothing when servicing fuel system. Fuel under this amount of pressure can penetrate skin causing serious or fatal injury.
NOTE:
To avoid leakage problems, the rail pressure sensor should not be removed unless it is to be replaced.
- Disconnect negative battery cable.
- Remove engine cover.
- Unplug electrical connector at fuel rail pressure sensor.
- Remove the right fuel rail.
- Position the fuel rail in a soft jawed vise.
- Remove rail pressure sensor.
