OA case from Oleg’s practice

  • Toyota Grand Highlander 2025 Check Engine, 8 EVAP entries: P24507E, P04419C, P142100, P142300. The purge valve, canister pump and sensors are fine, but the car had been in a collision — we recommended a leak search: EVAP system sealing and vacuum lines. How it went ↗

The explanation comes from the error code reference in the AvtoElektrik PRO app.
