Common Misdiagnosis Causes:
Exhaust cross-interference causes abnormal readings and drift
Aftertreatment system failures show as false sensor faults
Loose wiring and connectors lead to intermittent faults
Insufficient working temperature results in warm-up timeout error
Gradual sensor aging, not sudden damage
Wrong model, lost calibration or software incompatibility
Maintenance Diagnosis Tips：
High downstream NOx: Check urea, catalyst and ammonia slip first
Low reading & DPF clog: Probe covered by carbon, poor airflow
Fault when hot, normal when cold: Loose wiring or corroded connector
New sensor still errors: Wrong model, lost calibration or system fault
Warm-up error in, short trips: Insufficient temperature, not sensor damage
