Fuel Pressure Sensor: Installation
- When replacing the fuel injector assembly with a new one (2.0 L model)CAUTION: When replacing the fuel injector assembly, select the assembly with the same flow rate stratification number.NOTE: The flow rate stratification numbers of all 4 cylinders are identical.
(A) Flow rate stratification number (B) QR code - When reusing the fuel injector
- Prepare the fuel injector assembly using the following new parts. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>FUEL INJECTOR>REPLACEMENT .
- Fuel injector seal
- Slider washer
- Back-up ring
- O-ring seal
- Stopper ring
- Prepare the fuel injector assembly using the following new parts. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>FUEL INJECTOR>REPLACEMENT .
- Install the fuel injector holder.CAUTION: Always use a new fuel injector holder
- 2.0 L model
- 2.5 L model
- Align the protrusion of the fuel injector holder to the anti-rotation slot of the fuel injector pipe RH, and install the fuel injector straight to the fuel injector pipe RH.CAUTION:
- Always use a new fuel injector pipe RH .
- Degrease inside of the fuel injector insertion hole of the fuel injector pipe .
- Check the inside of the fuel injector insertion hole of the fuel injector pipe for foreign materials or damage .
- Be careful not to allow gasoline to contact with the fuel injector seal and the inside of the mounting hole .
- Apply liquid paraffin to the O-ring seal and install it .
- Be careful not to twist the O-ring seal .
- To prevent damage to the O-ring seal, insert the part straight along the fuel injector insertion axis without tilting it and avoid removing and inserting the part again .
- To prevent the tip of the fuel injector from bending, do not apply force to the fuel injector tip .
- Check that the tip of the fuel injector has no bend or damage .
- Make sure there is no gap between the fuel injector pipe and the fuel injector holder .
- Make sure there is no gap between the fuel injector and the fuel injector holder .
- 2.0 L model
(A) Protrusion portion (B) Anti-rotation slot (C) No gap allowed . - 2.5 L model
(A) Protrusion portion (B) Anti-rotation slot (C) No gap allowed . - Insert the fuel injector pipe RH and fuel injector as a single unit into the cylinder head, and align their positions. Then, evenly press the sections (A) and (B).CAUTION:
- When installing, apply liquid paraffin to the fuel injector seal .
- In order to prevent damaging the O-ring seal, do not install the fuel injector pipe and fuel injector by tilting them toward the cylinder head .
- Tighten the bolts which hold the fuel injector pipe RH.
Tightening torque :
19 N.m (1.9 kgf-m, 14.0 ft-lb)
- Temporarily tighten the fuel pressure sensor to the fuel injector pipe RH until it cannot be turned by hand.CAUTION: Always use a new fuel pressure sensor.
- Tighten the fuel pressure sensor.CAUTION:
- Be careful not to spill oil on the screw sections of the fuel pressure sensor and the fuel injector pipe RH .
- Be careful not to let foreign matter enter into the fuel pressure sensor during installation .
- The sensor should be installed perpendicularly to the fuel pressure sensor's threaded hole of the fuel injector pipe RH, and tightened to the specified torque .
- Do not recheck the tightening torque after tightening the fuel pressure sensor with specified torque .
Tightening torque :
46 N.m (4.7 kgf-m, 33.9 ft-lb)
- Connect the connector (A) and connector (B).
- Install the high-pressure fuel delivery pipe assembly. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DO)>HIGH PRESSURE FUEL DELIVERY PIPE>INSTALLATION>HIGH-PRESSURE FUEL DELIVERY PIPE ASSEMBLY .
- Install the air intake boot. Ref. to INTAKE (INDUCTION) (H4DO)>AIR INTAKE BOOT>INSTALLATION .
- Connect the ground terminal to battery sensor. Ref. to REPAIR CONTENTS>NOTE>BATTERY .
