Oxygen Heater Sensor Diagnostic Routine

US Patent:
53926439, Feb 28, 1995
Filed:
Nov 22, 1993
Appl. No.:
8/155673
Inventors:
Maura P. O'Kennedy - Livonia MI
Min Sway-Tin - Troy MI
Martin G. Yagley - Sterling Heights MI
Anson Lee - St. Clair MI
Assignee:
Chrysler Corporation - Highland Park MI
International Classification:
G01M 1500
US Classification:
731181
Abstract:
A diagnostic method is provided for sensing whether an oxygen sensor is still suitable for use in measuring the fuel-air mixture in the exhaust gases of an internal combustion engine. The method involves turning off a heater of an oxygen sensor when the engine is turned off and allowing the sensor to cool. While the sensor cools, the sensor resistance is measured by means of a large pull-up resistor and a small pull-up resistor, with the small resistor being switched into the circuit at regular intervals for a short period of time. The use of the small pull-up resistor not only increases the reliability of the measurements, but also aids in quickly determining when the sensor resistance has increased above a threshold value indicating the sensor is cool. When the sensor is sufficiently cool, the heater is turned on and the sensor is monitored for a decrease in resistance, indicating that the heater is functioning properly.
