At Meta Mechanics, we recently handled a Range Rover Velar with the Check Engine Light illuminated. This is a common issue that can be caused by a variety of factors, and our team of expert technicians thoroughly diagnosed the problem to pinpoint the underlying issues. Here’s a breakdown of the problems we discovered and the solutions we implemented:
Issues Found During the Check Engine Light Diagnosis:
- Faulty Oxygen Sensors
The vehicle’s oxygen sensors were malfunctioning, which caused incorrect fuel-to-air ratio readings, leading to poor fuel efficiency and increased emissions.
Solution:
We replaced the faulty oxygen sensors with OEM-grade parts to restore accurate readings and optimize the vehicle’s fuel efficiency and emissions. - Loose or Damaged Gas Cap
A common but often overlooked issue, the gas cap was found to be either loose or damaged, triggering the Check Engine Light due to the disruption in the fuel system’s pressure.
Solution:
We replaced the damaged gas cap and ensured it was securely tightened to prevent further fuel vapor leaks, allowing the vehicle’s fuel system to function properly. - Dirty Mass Air Flow (MAF) Sensor
The MAF sensor was clogged with debris and dirt, causing inaccurate readings of the amount of air entering the engine, leading to poor acceleration and engine performance.
Solution:
We cleaned the MAF sensor thoroughly and tested it for proper functionality. We also advised regular cleaning and maintenance to avoid similar issues in the future. - Worn Spark Plugs
The spark plugs showed signs of wear and fouling, which were causing misfires, rough idling, and reduced engine performance, triggering the Check Engine Light.
Solution:
We replaced the worn-out spark plugs with high-quality replacements, ensuring smooth ignition and efficient engine operation. Regular spark plug inspections were recommended for long-term engine health. - Exhaust Gas Recirculation (EGR) Valve Malfunction
The EGR valve was malfunctioning, leading to poor engine combustion and increased emissions. This can also contribute to knocking or hesitation during acceleration.
Solution:
We cleaned and reconditioned the EGR valve to restore proper functionality. If necessary, we replaced it to ensure optimal engine performance and reduced emissions.
