Component DescriptionNLEC1490The heated oxygen sensor 2 (rear), after three way catalyst, moni-
tors the oxygen level in the exhaust gas.
Even if switching characteristics of the heated oxygen sensor 1
(front) are shifted, the air fuel ratio is controlled to stoichiometric,
by the signal from the heated oxygen sensor 2 (rear).
This sensor is made of ceramic zirconia. The zirconia generates
voltage from approximately 1V in richer conditions to 0V in leaner
conditions.
Under normal conditions the heated oxygen sensor 2 (rear) is not
used for engine control operation.

CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-

On Board Diagnosis LogicNLEC1493The heated oxygen sensor 2 (rear) has a much longer switching
time between rich and lean than the heated oxygen sensor 1
(front). The oxygen storage capacity before the three way catalyst
causes the longer switching time. To judge the malfunctions of
heated oxygen sensor 2 (rear), ECM monitors whether or not the
voltage is too high during various driving conditions such as fuel-
cut.

Component DescriptionNLEC1761The camshaft position sensor is a basic component of the engine
control system. It monitors engine speed and piston position.
These input signals to the engine control system are used to con-
trol fuel injection, ignition timing and other functions.
The camshaft position sensor has a rotor plate and a wave-form-
ing circuit. The rotor plate has 360 slits for a 1É (POS) signal and
4 slits for a 180É (REF) signal. The wave-forming circuit consists
of Light Emitting Diodes (LED) and photo diodes.
The rotor plate is positioned between the LED and the photo diode.
The LED transmits light to the photo diode. As the rotor plate turns,
the slits cut the light to generate rough-shaped pulses. These
pulses are converted into on-off signals by the wave-forming circuit
and sent to the ECM.
The distributor is not repairable and must be replaced as an
assembly except distributor cap and rotor head.
ECM Terminals and Reference ValueNLEC1762Specification data are reference values and are measured between each terminal and ground.
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.
