1C-6 Engine Electrical Devices:
Installation
Reverse removal procedure noting the following.
• Tighten heated oxygen sensor (1) to specified torque.
Tightening torque
Heated oxygen sensor (a): 45 N·m (4.5 kg-m, 32.5
lb-ft)
• Install exhaust manifold referring to “Exhaust Manifold
Removal and Installation: in Section 1K”, if removed.
• Connect connector of heated oxygen sensor (1) and
clamp wire harness securely.
• After installing heated oxygen sensor, start engine
and check that no exhaust gas leakage exists.
Camshaft Position (CMP) Sensor Removal and
Installation
S4RS0A1306013
Removal
1) Disconnect negative cable at battery.
2) Disconnect connector from CMP sensor.
3) Remove camshaft position sensor from cylinder
head.
Installation
1) Install camshaft position sensor to cylinder head.
Tightening torque
CMP sensor bolt (a): 10 N·m (1.0 kg-m, 7.5 lb-ft)
2) Connect connector to CMP sensor securely.
3) Connect negative cable to battery.
Camshaft Position (CMP) Sensor Inspection
S4RS0A1306014
Visual check
• Check that O-ring is free from damage.
• Check that end face of sensor and signal rotor tooth
are free from any metal particles and damage.
Performance check
1) Remove metal particles on end face of CMP sensor,
if any.
2) Arrange 12 V battery (1) and connect its positive
terminal to “Vin” terminal (2) and negative terminal to
“Ground” terminal (3) of sensor. Then using
ohmmeter, measure resistance between “Vout”
terminal (4) of sensor and negative terminal of
battery by passing magnetic substance (iron) (5)
while keeping approximately 1 mm (0.03 in.) gap
with respect to end face of CMP sensor.
If resistance does not vary as specified below,
replace CMP sensor.
CMP sensor resistance
Resistance varies from less than 220
:
(ON) to
infinity (OFF) or from infinity (OFF) to less than 220
:
(ON)
[A]: HO2S-1
[B]: HO2S-2
