(b) Images are difficult to discern even in normal
conditions if:
(1) Camera screen is frosted over (the image
immediately after turning the ignition switch to
the on position may be blurred or darker than
normal).
(2) A strong beam of light, such as a sunbeam or
headlight, hits the camera.
(3) It is too dark around the camera (at night, etc.).
(4) The ambient temperature around the camera is
either too high or too low.
HINT:
When a strong light, such as a sunbeam
reflected off the vehicle's body, hits the camera,
the image may be blurred. This is called the
"SMEAR" phenomenon, peculiar to the CCD
camera.

DESCRIPTION
The exhaust camshaft's Variable Valve Timing (VVT) sensor consists of a magnet and MRE (Magneto
Resistance Element).
The exhaust camshaft has a sensor plate with 3 teeth on its outer circumference.
When the exhaust camshaft rotates, changes occur in the air gaps between the 3 teeth and MRE, which
affects the magnet. As a result, the resistance of the MRE material fluctuates. The VVT sensor converts
the exhaust camshaft rotation data to pulse signals, uses the pulse signals to determine the camshaft
angle, and sends it to the ECM.
MONITOR DESCRIPTION
If no signal is transmitted by the VVT (for exhaust camshaft) sensor despite the engine revolving, or the
rotations of the exhaust camshaft and the crankshaft are not synchronized, the ECM interprets this as a
malfunction of the sensor.

MONITOR DESCRIPTION
The ECM uses the sensors mounted in front of and behind the three-way catalyst (TWC) to monitor its
efficiency. The first sensor, an Air Fuel ratio (A/F) sensor, sends pre-catalyst A/F ratio information to the
ECM. The second sensor, a heated oxygen sensor (O2S), sends post-catalyst information to the ECM.
The ECM compares these 2 signals to judge the efficiency of the catalyst and the catalyst's ability to store
oxygen. During normal operation, the TWC stores and releases oxygen as needed. The capacity to store
oxygen results in a low variation in the post-TWC exhaust stream.
If the catalyst is functioning normally, the waveform of the heated oxygen sensor slowly switches between
RICH and LEAN. If the catalyst is deteriorated, the waveform will alternate frequently between RICH and
LEAN. As the catalyst efficiency degrades, its ability to store oxygen is reduced and the catalyst output
becomes more variable. When running the monitor, the ECM compares sensor 1 signals (A/F sensor)
over a specific amount of time to determine catalyst efficiency. The ECM begins by calculating the signal
length for both sensors (for the rear oxygen sensor, the ECM uses the output voltage signal length). If the
oxygen sensor output voltage signal length is greater than the threshold (threshold is calculated based on
the A/F sensor signal length), the ECM concludes that the catalyst is malfunctioning. The ECM will turn on
the MIL and a DTC will be set.

• Bank 2 refers to the bank that does not include cylinder No. 1.
