Product Description
Used for NOx detection in diesel vehicle exhaust. Misdiagnosis may occur due to
exhaust interference, aftertreatment faults, loose wiring, temperature conditions,
calibration compatibility and cross-sensitivity.
We focus on premium material selection and strict production quality control. Every component is precisely matched to ensure stable signal transmission, high detection accuracy and excellent compatibility with original vehicles.
Effectively resist high temperature, corrosion and harsh exhaust environment, greatly extending the service life. Our NOx sensors feature outstanding durability, reliable long-term performance and lower failure rates, providing you with long-lasting and cost-effective replacement solutions.

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
