Test 2 - 5:

SYMPTOM
P1195-O2 SENSOR 1/1 SLOW DURING CATALYST MONITOR

WHEN MONITORED
With the engine running, coolant greater than 170 °F, open throttle, steady to slightly increasing vehicle speed greater than 18 mph but less than 55 mph, with a light load on the engine, for a period no less than 5 minutes.

SET CONDITION
The oxygen sensor signal voltage is switching from below 0.39 of a volt to above 0.6 of a volt and back fewer times than required.

POSSIBLE CAUSES
- Good trip equal to zero
- Exhaust leak
- Resistance in the O2 sensor signal circuit
- Resistance in the (K4) O2 sensor ground circuit
- O2 sensor
