Code P208C Buick Description
The P208C Buick diagnostic trouble code (DTC) refers to the reductant pump control circuit registering low voltage. This code is typically associated with vehicles equipped with a diesel engine and a selective catalytic reduction (SCR) system. The reductant pump is responsible for supplying the necessary diesel exhaust fluid (DEF), also known as AdBlue, to the SCR system. The SCR system uses DEF to reduce harmful nitrogen oxide emissions into nitrogen and water, which helps vehicles comply with emissions standards.
Common Causes of P208C Buick
- Faulty reductant pump
- Damaged wiring or connectors in the control circuit
- Blown fuse related to the reductant pump
- Malfunctioning powertrain control module (PCM)
Symptoms of P208C Buick
- Illuminated check engine light
- Reduced fuel efficiency
- Engine misfires or hesitation
- Increased emissions
- Reduced engine performance
How to Fix P208C Buick
- Begin by performing a visual inspection of the reductant pump, wiring, and connectors to check for any visible damage or corrosion.
- Use a multimeter to test the voltage output of the reductant pump control circuit to determine if it is within the manufacturer's specified range.
- Check and replace any blown fuses related to the reductant pump.
- If necessary, replace the reductant pump or repair damaged wiring/connectors to restore proper voltage to the pump.
- Clear the DTC and reset the check engine light after completing the repair to ensure the issue has been resolved.
