Test TC-192A: Slow O2S 1/1 During Catalyst Monitor
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
- For O2 sensor/model identification see O2 SENSOR 1/1 IDENTIFICATION table. This trouble code will set when upstream O2S signal voltage is switching from less than .39 volt to more than .60 volt and back fewer times than required. Possible causes are: exhaust leak, fuel contamination, weak upstream O2S with deteriorated catalyst, dirty or wet O2S 1/1 connector or engine mechanical failure. Go to next step.O2 SENSOR 1/1 IDENTIFICATION
Application Location Avenger, Sebring Coupe & Talon 4-Cylinder Upstream O2S V6 Rear Bank Upstream O2S Breeze, Cirrus, Neon, Sebring Conv. & Stratus 4-Cylinder Upstream O2S V6 Upstream O2S - Start engine. Inspect exhaust system for leaks between engine and catalytic converter(s). If exhaust leaks are not present, go to next step. If exhaust leaks are present, repair or replace exhaust system as necessary. Perform TEST VER-5A .
- Inspect exhaust system for excessive smoke caused by oil or coolant consumption. If an oil or coolant consumption condition is not present, go to next step. If an oil or coolant consumption condition is present, repair engine as necessary and replace O2S 1/1. Perform TEST VER-5A .
- Turn ignition off. Disconnect O2S 1/1 connector. Inspect O2S 1/1 connector for pushed out terminals or damage. Repair connector as necessary. Perform TEST VER-5A . If connector is okay, go to next step.
- Using an ohmmeter, check resistance between O2S 1/1 sensor ground circuit and chassis ground at O2S 1/1 connector (harness side). See O2S 1/1 CONNECTOR WIRE IDENTIFICATION (HARNESS SIDE) table. If resistance is 5 ohms or more, repair open O2S 1/1 sensor ground circuit. Perform TEST VER-5A . If resistance is less than 5 ohms, go to next step.
- Disconnect Powertrain Control Module (PCM) connector. Inspect PCM connector for pushed out terminals or damage. Repair connector as necessary. Perform TEST VER-5A . If connector is okay, replace O2S 1/1. Perform TEST VER-5A .

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
