Response rate is the time required for the sensor to

switch from lean to rich once it is exposed to a richer
than optimum A/F mixture or vice versa. As the sen-
sor starts malfunctioning, it could take longer to
detect the changes in the oxygen content of the
exhaust gas.

The output voltage of the O2S ranges from 0 to 1

volt. A good sensor can easily generate any output
voltage in this range as it is exposed to different con-
centrations of oxygen. To detect a shift in the A/F
mixture (lean or rich), the output voltage has to
change beyond a threshold value. A malfunctioning
sensor could have difficulty changing beyond the
threshold value.

DTC 21—HEX 67, 69, 7C, and 7D—OXYGEN
SENSOR HEATER MONITOR

If there is an oxygen sensor (O2S) DTC as well as

a O2S heater DTC, the O2S fault MUST be repaired
first. After the O2S fault is repaired, verify that the
heater circuit is operating correctly.

Effective control of exhaust emissions is achieved

by an oxygen feedback system. The most important
element of the feedback system is the O2S. The O2S
is located in the exhaust path. Once it reaches oper-
ating temperature 300° to 350°C (572 °to 662°F), the
sensor generates a voltage that is inversely propor-
tional to the amount of oxygen in the exhaust. The
information obtained by the sensor is used to calcu-
late the fuel injector pulse width. This maintains a
14.7 to 1 Air Fuel (A/F) ratio. At this mixture ratio,
the catalyst works best to remove hydrocarbons (HC),
carbon monoxide (CO) and nitrogen oxide (NOx) from
the exhaust.

The voltage readings taken from the O2S are very

temperature sensitive. The readings are not accurate
below 300°C. Heating of the O2S is done to allow the
engine controller to shift to closed loop control as
soon as possible. The heating element used to heat
the O2S must be tested to ensure that it is heating
the sensor properly.

The O2S circuit is monitored for a drop in voltage.

The sensor output is used to test the heater by iso-
lating the effect of the heater element on the O2S
output voltage from the other effects.

DTC 32—HEX 2E—EGR MONITOR

The Powertrain Control Module (PCM) performs

an on-board diagnostic check of the EGR system.

The EGR system consists of two main components:

a vacuum solenoid and a vacuum operated valve with
a back pressure transducer. The EGR monitor is used
to test whether the EGR system is operating within
specifications. The diagnostic check activates only
during selected engine/driving conditions. When the
conditions are met, the EGR is turned off (solenoid
energized) and the O2S compensation control is mon-

itored. Turning off the EGR shifts the air fuel (A/F)
ratio in the lean direction. The O2S data should indi-
cate an increase in the O2 concentration in the com-
bustion chamber when the exhaust gases are no
longer recirculated. While this test does not directly
measure the operation of the EGR system, it can be
inferred from the shift in the O2S data whether the
EGR system is operating correctly. Because the O2S
is being used, the O2S test must pass its test before
the EGR test.

DTC 43—HEX 6A,6B, 6C, 6D, 6E, AE, and
AF—MISFIRE MONITOR

Excessive engine misfire results in increased cata-

lyst temperature and causes an increase in HC emis-
sions. Severe misfires could cause catalyst damage.
To prevent catalytic convertor damage, the PCM
monitors engine misfire.

The Powertrain Control Module (PCM) monitors

for misfire during most engine operating conditions
(positive torque) by looking at changes in the crank-
shaft speed. If a misfire occurs the speed of the
crankshaft will vary more than normal.

DTC 51/52—HEX 76, 77, 78, and 79—FUEL
SYSTEM MONITOR

To comply with clean air regulations, vehicles are

equipped with catalytic converters. These converters
reduce the emission of hydrocarbons, oxides of nitro-
gen and carbon monoxide. The catalyst works best
when the air fuel (A/F) ratio is at or near the opti-
mum of 14.7 to 1.

The PCM is programmed to maintain the optimum

air/fuel ratio of 14.7 to 1. This is done by making
short term corrections in the fuel injector pulse width
based on the O2S output. The programmed memory
acts as a self calibration tool that the engine control-
ler uses to compensate for variations in engine spec-
ifications, sensor tolerances and engine fatigue over
the life span of the engine. By monitoring the actual
air-fuel ratio with the O2S (short term) and multiply-
ing that with the program long-term (adaptive) mem-
ory and comparing that to the limit, it can be
determined whether it will pass an emissions test. If
a malfunction occurs such that the PCM cannot
maintain the optimum A/F ratio, then the MIL will
be illuminated.

DTC 64—HEX 70, and B4—CATALYST
MONITOR

To comply with clean air regulations, vehicles are

equipped with catalytic converters. These converters
reduce the emission of hydrocarbons, oxides of nitro-
gen and carbon monoxide.

Normal vehicle miles or engine misfire can cause a

catalyst to decay. A meltdown of the ceramic core can
cause a reduction of the exhaust passage. This can
