Important Operation Notes
1.
Before installing the lambda sensor, apply a small amount of non-lead containing
antiseize compound to its threads. Do not get the compound on the sensor’s tip.
2.
Do not operate an engine for more than three minutes with the lambda sensor in the
exhaust and the control module’s power off. If the sensor is off in a running engine
for a longer period, soot and water will condense in the sensor and may reduce its
sensitivity.
3.
Do not use the lambda sensor in exhaust systems in which water is sprayed into the
exhaust. Water striking the sensor may cause permanent sensor damage.
4.
Do not put the lambda sensor in a heavily sooting or oil-burning engine.
5.
Use of the lambda sensor with leaded fuels over time may reduce the sensitivity of the
sensor.
6.
Do not use the lambda sensor in a location where the temperature is greater than 950 deg.
C (1742 deg. F) or if the pressure is not between 0.8 to 1.3 atm (23.9 to 38.9 inches Hg,
81 to 132 kPa).
7.
Route and cable-tie the wiring harness away from hot or moving objects and ignition
wires.
8.
Do not remove or attach the lambda sensor from the instrument harness when the control
module power is on.
9.
Do not drop the lambda sensor onto a hard surface.
10.
Do not expose the lambda sensor to flammable substances.
11. Do not attempt to wash the lambda sensor with any solvent or compressed air.
12. Do not use the AFM with a sensor for which it is not programmed.
