OPERATION 
The Oxygen (02) sensor is a device which pro- 
duces an electrical voltage when exposed to the oxy- 
gen present in the exhaust gases. The sensor is 
mounted in the exhaust system, usually in the mani- 
fold or a boss located on the down pipe before the 
catalyst. The oxygen sensors used on some models 
are electrically heated internally for faster switching 
when the engine is started cold. The oxygen sensor 
produces a voltage within 0 and 1 volt. When there is 
a large amount of oxygen present (lean mixture), the 
sensor produces a low voltage (less than 0.4~). When 
there is a lesser amount present (rich mixture) it pro- 
duces a higher voltage (0.6-I .Ov). The stoichiometric 
or correct fuel to air ratio will read between 0.4 and 
0.6~. By monitoring the oxygen content and convert- 
ing it to electrical voltage, the sensor acts as a rich- 
lean switch. The voltage is transmitted to the PCM. 
Some models have two sensors, one before the 
catalyst and one after. This is done for a catalyst eff i- 
ciency monitor that is a part of the OBD-II engine 
controls. The one before the catalyst measures the 
exhaust emissions right out of the engine, and sends 
the signal to the PCM about the state of the mixture 
as previously talked about. The second sensor re- 
ports the difference in the emissions after the exhaust 
gases have gone through the catalyst. This sensor re- 
ports to the PCM the amount of emissions reduction 
the catalyst is performing. 
The oxygen sensor will not work until a predeter- 
mined temperature is reached, until this time the 
PCM is running in what as known as OPEN LOOP 
operation. OPEN LOOP means that the PCM has not 
yet begun to correct the air-to-fuel ratio by reading the oxygen sensor. After the engine comes to operat- 
ing temperature, the PCM will monitor the oxygen 
sensor and correct the air/fuel ratio from the sensor’s 
readings. This is what is known as CLOSED LOOP 
operation. 
A Heated Oxygen Sensor (H02S) has a heating el- 
ement that keeps the sensor at proper operatmg tem- 
perature during all operating modes. Maintaining 
correct sensor temperature at all times allows the 
system to enter into CLOSED LOOP operation 
sooner. 
In CLOSED LOOP operation, the PCM monitors 
the sensor input (along with other inputs) and adjusts 
the injector pulse width accordingly. During OPEN 
LOOP operation, the PCM ignores the sensor input 
and adjusts the injector pulse to a preprogrammed 
value based on other inputs. 
TESTING 
# See Figure 37 
93154p36 Fig. 37 The HD2S can be monitored with an 
appropriate and Data-stream capable scan 
tool 
Do not pierce the wires when testing this 
sensor; this can lead to wiring harness dam- 
age. Backprobe the connector to properly 
read the voltage of the HD2S. 
1. Disconnect the H02S. 
2. Measure the resistance between PWR and 
GND terminals of the sensor. Resistance should be 
approximately 6 ohms at 68°F (20°C) If resistance is 
not within specification, the sensor’s heater element 
is faulty. 
3. With the H02S connected and engine running, 
measure the voltage with a Digital Volt-Ohmmeter 
(DVOM) between terminals 
HD2S and SIG RTN (GND) of the oxygen sensor connector. Voltage 
should fluctuate between 0.01-l .O volts. If voltage 
fluctuation is slow or voltage is not within specifica- 
tion, the sensor may be faulty.

2. Raise and support the vehicle safely.

CHASSIS ELECTRICAL 6-7 
When working on any electrical component on the 
vehicle, it is always a good idea to disconnect the 
negative (-) battery cable. This will prevent potential 
damage to many sensitive electrical components 
such as the Powertrain Control Module (PCM), radio, 
alternator, etc. 
*Any time you disengage the battery cables, 
it is recommended that you disconnect the negative (-) battery cable first. This will pre- 
vent your accidentally grounding the positive 
(+) terminal to the body of the vehicle when 
disconnecting it, thereby preventing damage 
to the above mentioned components. 
Before you disconnect the cable(s), first turn the 
ignition to the OFF position. This will prevent a draw 
on the battery which could cause arcing (electricity 
trying to ground itself to the body of a vehicle, just 
like a spark plug jumping the gap) and, of course, damaging some components such as the alternator 
diodes. 
When the battery cable(s) are reconnected (nega- 
tive cable last), be sure to check that your lights, 
windshield wipers and other electrically operated 
safety components are all working correctly. If your 
vehicle contains an Electronically Tuned Radio (ETR), 
don’t forget to also reset your radio stations. Ditto for 
the clock.

cautions in the beginning of this section. 
2. Position the front wheels in the straight-ahead 
position and place the key in the LOCK position. Re- 
move the key from the ignition lock cylinder. 
3. Disconnect the negative battery cable and in- 
sulate the cable end with high-quality electrical tape 
or similar non-conductive wrapping. 
4. Wait at least one minute before working on the 
vehicle. The air baa svstem is desianed to retain 
enough voltage to deploy the air bag for a short pe- 
riod of time after the battery has been disconnected.
