Code C1562 GMC Description
The C1562 diagnostic trouble code (DTC) for GMC vehicles indicates a malfunction in the Device Voltage Reference Output 2 circuit. This code is typically triggered when the powertrain control module (PCM) detects an issue with the voltage reference signal being sent to a specific component or system within the vehicle. The voltage reference signal is crucial for ensuring proper operation of various sensors and electronic components in the vehicle.
Common Causes of C1562 GMC
- Faulty voltage reference output sensor
- Wiring or connector issues in the voltage reference circuit
- PCM malfunction
- Electrical system issues
- Corrosion or damage to the circuit components
Symptoms of C1562 GMC
- Rough idling or engine stalling
- Hesitation or lack of power during acceleration
- Poor fuel efficiency
- Inability to start the vehicle
- Illumination of the check engine light
How to Fix C1562 GMC
- Begin by using a diagnostic scanner to retrieve the specific trouble code and further diagnose the issue.
- Inspect the voltage reference output sensor, wiring, and connectors for any signs of damage, corrosion, or loose connections.
- Test the voltage reference output circuit using a multimeter to ensure proper voltage levels are being sent to the component.
- Replace the faulty voltage reference output sensor if necessary, and repair any damaged wiring or connectors.
- Clear the DTC from the PCM's memory and perform a test drive to verify that the issue has been resolved.
