Customer Concern: GMC Check Engine Light On
A GMC vehicle came to our Al Quoz workshop with the check engine light illuminated. The vehicle was still driving, but the customer wisely decided to have it inspected before the problem worsened. Ignoring warning lights can lead to costly engine repairs — especially in Dubai’s demanding driving conditions.
Advanced Computer Diagnostics at AutoDoctor – Al Quoz
Our technicians connected a professional diagnostic scanner and retrieved a Diagnostic Trouble Code (DTC) related to a knock sensor malfunction.
We performed:
- Full OBD computer scan
- Fault code verification
- Wiring and connector inspection
- Sensor performance testing
- After confirming the issue, we recommended replacing the faulty knock sensor.
- Accurate diagnostics save time and prevent unnecessary parts replacement.
What Does a GMC Knock Sensor Do?
The knock sensor detects abnormal combustion (engine knocking or pinging). It sends signals to the engine control module (ECM), which adjusts ignition timing to protect the engine.
If the knock sensor fails, you may experience:
- Check engine light ON
- Reduced engine performance
- Poor fuel economy
- Sluggish acceleration
- Potential long-term engine damage
In Dubai’s hot climate, engine components must function properly to avoid overheating and performance issues.
