What is CID 162:
CID 162 refers to an issue with the vehicle's air intake system, specifically the air mass flow (MAF) sensor. The ECM detects that the sensor is malfunctioning or providing incorrect data, affecting the air-fuel mixture and causing engine performance issues, poor acceleration, or reduced fuel efficiency.
Why This Happens:
- Faulty air mass flow sensor.
- Shorted or damaged wiring in the sensor circuit.
- Loose or corroded connectors.
- Blockages or contamination in the air intake system.
- ECM misinterpreting the sensor’s data.
How to Fix It:
- Inspect the air mass flow sensor for damage or malfunction.
- Test the sensor’s voltage and resistance to ensure proper operation.
- Check wiring and connectors for visible damage or corrosion.
- Replace the faulty sensor if necessary.
- Inspect the air intake system for blockages or contamination.
How to Avoid It Before It Happens:
- Regularly inspect the air mass flow sensor and wiring.
- Perform routine air intake system maintenance.
- Keep connectors clean and corrosion-free.
- Perform diagnostic checks to monitor sensor performance.
- Clue’s equipment maintenance services help monitor air intake systems and prevent sensor issues before they affect engine performance.
