1) Front HO2S is mounted in exhaust pipe below exhaust
header. Rear HO2S is mounted behind catalytic converter. HO2S is
equipped with a permanent pigtail which must be protected from damage
when HO2S is removed. Ensure HO2S is free of contaminants. Avoid using
cleaning solvents of any type.
2) HO2S may be difficult to remove when engine temperature is
less than 120
F (48 C). If using original sensor, always use anti-
seize compound on threads before installation. New sensor threads are
precoated with anti-seize. Tighten HO2S to specification. See
TORQUE SPECIFICATIONS .
THROTTLE BODY
Removal
1) Relieve fuel pressure. See FUEL SYSTEM PRESSURE RELEASE.
Drain enough coolant to ensure coolant level is below throttle body.
Disconnect air intake hose.
2) Remove accelerator, cruise control and A/T throttle valve
cables (if equipped). Disconnect fuel vapor hose, electrical harness
connector, vacuum hose and coolant hoses. Remove throttle body
retaining bolts.
Disassembly
Remove throttle position sensor. Remove idle air control
motor. Remove throttle bracket and connector bracket (if equipped).
Remove idle position switch and adjusting nut (if equipped).
CAUTION: DO NOT remove throttle valve. DO NOT use cleaning solvents
on throttle position sensor, idle air control motor or idle
position switch.
Cleaning
1) Clean all parts except throttle position sensor, idle air
control motor and idle position switch in solvent.
WARNING: Safety glasses MUST be worn whenever compressed air is used
for parts cleaning.
2) Check vacuum port and passage for clogging. Clean vacuum,
vapor and fuel passages using compressed air.
Reassembly
To reassemble, reverse disassembly procedure.
Installation
To install, reverse removal procedure.
THROTTLE POSITION (TP) SENSOR
Removal & Installation
Throttle Position (TP) sensor is located on throttle body.
Disconnect TP sensor electrical connector. Remove TP sensor screws and
TP sensor. To install, reverse removal procedure. Tighten TP sensor
screws to specification. See TORQUE SPECIFICATIONS. For TP sensor
adjustment procedure, see D - ADJUSTMENTS article.
TURBOCHARGERS
Removal (Eclipse)
1) Disconnect negative battery cable. Drain engine coolant
and oil. On models equipped with A/C, remove condenser fan motor
assembly. Remove front heated oxygen sensor. Remove oil dipstick guide
and "O" ring.
Page 999 of 1501
2) Disconnect air intake hose and vacuum hoses. Remove air
hose and air outlet housing. Remove heat protectors. Disconnect
exhaust pipe. Remove power steering oil pump and bracket. Remove
engine hanger bracket. Disconnect oil inlet pipe.
3) Disconnect engine coolant hoses and tubes from
turbocharger. Remove exhaust manifold nuts and bolts. Remove exhaust
manifold and gaskets. Disconnect oil pressure and return pipes. Remove
turbocharger and exhaust manifold assembly. Separate turbocharger from
exhaust manifold.
Removal (3000GT - Front)
1) Disconnect negative battery cable. Drain engine oil and
coolant. Remove radiator. Disconnect exhaust pipe. Remove air intake
hose, air hoses and air pipe. Remove generator and belt. Remove oil
dipstick guide.
2) Remove heat protector. Disconnect front heated oxygen
sensor connector. Remove oil return pipe. Remove turbocharger support
bracket, and remove turbocharger from exhaust manifold.
Removal (3000GT - Rear)
1) Disconnect battery cables, and remove battery. Drain
engine oil and cooling system. Remove accelerator cable. Remove air
hose, air pipe and heat protectors. Disconnect clutch booster vacuum
hose. Remove air intake hoses and EGR pipe. Disconnect heated oxygen
sensor connectors.
2) Remove oil pipe and EGR valve. Disconnect exhaust fitting,
and remove rear heat protector. Remove oil return pipe. Remove
turbocharger assembly.
Inspection (All Models)
Check turbine and compressor wheels for cracking and other
damage. Ensure turbine and compressor wheels turn smoothly. Check for
oil leakage from turbocharger assembly. Check for proper wastegate
valve operation. See I - SYSTEM/COMPONENT TESTS article.
CAUTION: Apply light coat of oil to inner surface of flared area on
water pipe (flare nut fitting) before connecting to engine.
Installation (All Models)
1) To install, reverse removal procedure. Before oil pipe
flare nut (above turbocharger) is installed, pour clean engine oil
into turbocharger oil pipe installation hole. Ensure oil and air hoses
are properly installed and securely clamped.
2) Use NEW gaskets. Adjust accelerator cable (if necessary).\
Refill engine oil and coolant. Check for oil and coolant leaks.
Tighten all bolts to specification. See TORQUE SPECIFICATIONS.
