Maintenance
  • Inspect for physical damage or clogging
  • Check for error codes P0420 or P0430
  • Ensure proper oxygen sensor functionality
  • Replace catalytic converter if sensor indicates failure

Exhaust Gas Recirculation (EGR) System

The EGR system reduces nitrogen oxide emissions by recirculating a portion of exhaust gases back into the engine. This section covers its sensors and maintenance.

EGR Valve Sensor

  • Detects carbon buildup in the valve
  • Sends feedback to the ECU
  • Common error code: P0401 (insufficient flow)
Cleaning and Replacement
  • Clean EGR valve with carburetor cleaner
  • Inspect for vacuum leaks
  • Replace EGR valve if stuck or unresponsive
  • Reset ECU after maintenance
