EXHAUST MANIFOLD AND TURBOCHARGER
14. Loosen exhaust manifold mounting nuts in the reverse order
specified in the figure.
15. Rotate the exhaust manifold and turbocharger assembly so that
the rear side (EGR cooler mounting side) faces upward. And
then pull out the assembly from between the engine and the air
conditioning piping.
CAUTION:
Be careful not to deform each turbocharger piping when
pulling out the assembly.
INSTALLATION
●When a stud bolt is pulled out, tighten it to the following torque:
●Tighten the exhaust manifold mounting nuts in the following procedure:
1. Tighten the nuts in the order specified in the figure.
2. Re-tighten the nuts 1 to 4.
3. Install the gasket so that the alignment protrusion faces the No.
4 port.
4. Install in reverse order of removal.
INSPECTION AFTER INSTALLATION
Start engine and raise engine speed to check no exhaust emission leaks.

INSTALLATION
Before installation, remove old liquid gasket from mating surface of all liquid gasket applied parts.
1. Install cylinder head gasket.
●Cylinder head gasket to be installed is selected by its thick-
ness through the following procedure.
–When replacing gasket alone
• Install a gasket with same thickness as that of the one
removed.
• Identify the thickness of gasket by the number of cut-outs on
the RH side.
*: Measured with head bolts tightened
• Gasket thickness can be identified at the location shown in
the figure by the numbers of cut-outs before removal.
–When the following parts have been repaired/replaced:
●With cylinder block upper surface and/or crankshaft pin jour-
nal ground
●With cylinder block, pistons, connecting rods, and/or crank-
shaft replaced
a. Set piston at a point close to TDC.
b. Set a dial gauge at the location as shown in the figure. Turning
crankshaft gradually, set the gauge scale to “0” where the piston
protrusion is maximized.
c. Move the dial gauge stand so that the tip of dial gauge can con-
tact the cylinder block. Read the difference.
d. Measure at two locations per cylinder, that is eight locations for four cylinders. Select gasket based on the
maximum protrusion of eight measurements.

DTC P0335 CRANKSHAFT POSISTION SENSOR (TDC)PFP:23731
DescriptionEBS004RQ
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with 23 protrusions)
installed to the fly wheel. The datum signal output is detected 15°
signal and sent to the ECM. The sensor signal is used for fuel injec-
tion control and fuel injection timing control.
CONSULT-II Reference Value in Data Monitor ModeEBS004RR
Specification data are reference values.
ECM Terminals and Reference ValueEBS004RS
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

paint. If it gets on a painted surface, wipe it off immediately and wash with water.
●Do not bend or twist the brake hose sharply, or strongly pull it.
●Cover brake fluid line connections to prevent dust and other foreign material from entering.
1. Connect a vinyl tube to the air bleeder.
2. Drain brake fluid gradually from the air bleeder of each wheel while depressing the brake pedal.
3. Using a flare nut wrench, remove brake tube flare nuts and dis-
connect brake tube from the brake hose.
4. Remove union bolts and disconnect caliper assembly from the
brake hose.
5. First remove lock spring from brake tube and strut mounting
positions. Then remove brake hose.
INSTALLATION
CAUTION:
●Refill with new brake fluid “DOT 3” or “DOT4”.
●Never reuse drained brake fluid.
1. Connect brake hose to caliper assembly and tighten union bolts to the specified torque.
CAUTION:
●Securely connect brake hose to the protrusions on the cylinder body.
●Do not reuse the copper washer for union bolts.
2. Connect brake hose to the strut and fix with lock spring.
3. Connect brake hose to brake tube. Temporarily tighten flare nuts by hand as far as they will go. Secure
them with the lock spring.
4. Using a flare nut torque wrench, tighten to the specified torque.
