O2 Sensor 1/1 Slow During Catalytic Monitor
2004-2008 Chrysler Crossfire 3.2L V6
Description
The PCM has detected that the upstream oxygen sensor on Bank 1 is responding too slowly during the catalytic converter efficiency monitor. The sensor switching rate is below the threshold needed for accurate catalyst monitoring.
Symptoms
- Check Engine Light
- Failed emissions test
- Slightly reduced fuel economy
- Possible rough idle
Common Causes
- Aging or contaminated upstream O2 sensor
- Exhaust leak near the O2 sensor
- Wiring issue causing signal delay
- Fuel contamination affecting sensor response
- Catalytic converter deterioration affecting sensor readings
Diagnostic Steps
- Monitor O2 sensor switching frequency on scan tool (should switch rapidly at steady cruise)
- Inspect O2 sensor wiring for damage or high resistance
- Check for exhaust leaks near sensor location
- Compare sensor response time to specification
- Inspect catalytic converter condition
Repair Notes
Replace the upstream O2 sensor Bank 1 if response time exceeds specification.
