Typical HO2S response rate entry conditions : Minimum Maximum
Short Term Fuel Trim Range 90% 110%
Engine Coolant Temp 150 oF 240 oF
Intake Air Temp 140 oF
Engine Load 20% 50%
Vehicle Speed 37 mph 55 mph
Engine RPM 1500 rpm 3000 rpm
Time since entering closed loop fuel 10 seconds

Typical HO2S response rate malfunction thresholds:
Voltage amplitude: < 0.4 volts

HO2S response rate temporary disablement conditions ( other than entry requirements ) :
Disabled if a lack of switching fault is present, also sensors noted in “Sensors OK” section.


Rear HO2S Signal.

A functional test of the rear HO2S sensors is done dur ing normal vehicle operation. The peak rich and lean
voltages are continuously monitored. Voltages that exceed the calibratable rich and lean thresholds
indicate a functional sensor. If the voltages have not ex ceeded the thresholds after a long period of vehicle
operation, the air/fuel ratio may be forced rich or lean in an attempt to get the rear sensor to switch. This
situation normally occurs only with a green catalyst (< 500 miles). If the sensor does not exceed the rich
and lean peak thresholds, a malfunction is indicated.

Rear HO2S Check Operation:
DTCs Bank 1 - P0136, Bank 2 - P0156
Monitor execution once per driving cycle
Monitor Sequence after 'Upstream Response' test
Monitoring Duration 20sec for excursion

Typical Rear HO2S check entry conditions : Minimum Maximum
Inferred exhaust temperature range 400 oF 1600 oF
Rear HO2S heater-on time 120 seconds
Throttle position part throttle
Engine RPM (forced excursion only) 1000 rpm none

Typical Rear HO2S check malfunction thresholds:
Does not exceed rich and lean threshold envelope: Rich < 0.25 volts
Lean > 0.65 volts

Rear HO2S temporary disablement conditions (other than entry requirements) :
None.

HO2S Heaters, front and rear.

The HO2S heaters are monitored for circuit continuity. A HO2S heater fault is determined by turning the
heater on and off and looking for corresponding voltage or current change in the heater output driver
circuit in the PCM.

HO2S Heater Monitor Operation:
DTCs Bank 1 - P0135 Front, P0141 Rear
Bank 2 - P0155 Front, P0161 Rear
Monitor execution Change of Heater state (at least once per drive cycle).
Monitor Sequence none
Monitoring Duration < 5 seconds

Typical HO2S heater check malfunction thresholds:
Indicated voltage or current does not match commanded state.

HO2S heater temporary disablement conditions (other than entry requirements) :
None.
