Code P116E 2017 GMC Sierra Description
The P116E diagnostic trouble code (DTC) for a 2017 GMC Sierra specifically relates to the O2 Pump Current Control Circuit Low Voltage in relation to the NOx Sensor 1. This code indicates an issue with the operation of the O2 pump current control circuit, which is responsible for regulating and controlling the flow of current to the NOx sensor. The NOx sensor is a crucial component in the vehicle's emissions control system, as it monitors the levels of nitrogen oxide (NOx) in the exhaust gases.
Common Causes of P116E 2017 GMC Sierra
- Faulty O2 Pump Current Control Circuit: The most common cause of this code is a malfunction in the O2 pump current control circuit itself.
- Wiring Issues: Poor electrical connections or damaged wiring to the O2 pump current control circuit can also trigger this code.
- Sensor Malfunction: A malfunctioning NOx sensor can also lead to this code being triggered.
- Software or Calibration Errors: Issues with the vehicle's software or calibration can also cause the O2 pump current control circuit to operate improperly.
- Environmental Factors: Extreme temperatures or environmental conditions can also impact the operation of the O2 pump current control circuit.
Symptoms of P116E 2017 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
