Code P1192 2014 Chevrolet Silverado Description
The P1192 code on a 2014 Chevrolet Silverado indicates a problem with the O2 low reference circuit for NOx Sensor 1. This sensor is responsible for monitoring the levels of nitrogen oxide (NOx) in the exhaust gases to ensure compliance with emissions standards. The O2 low reference circuit provides a baseline voltage for the sensor to compare the oxygen levels in the exhaust gases accurately. When this circuit malfunctions, it can lead to inaccurate readings and affect the vehicle's performance.
Common Causes of P1192 2014 Chevrolet Silverado
- Faulty NOx sensor
- Damaged wiring or connectors
- Corrosion in the electrical connections
- ECM software issues
- Exhaust leaks near the sensor
