CLAAS 7772h – Claas Eng A15 Engine Module: Intake Air Temperature of the Turbocharger Excessively High

The intake air temperature of the turbocharger is excessively high, causing the engine power to be reduced by 20% per minute until it reaches 50% of its nominal power. The power is recovered at a rate of 20% per minute once the issue is resolved.

1. 1

   Inspect the intake air temperature sensor (B1)

   Verify that the sensor is properly connected and functioning. Check for any signs of damage or contamination.

2. 2

   Check the air filter

   Ensure the air filter is clean and not clogged, as a restricted air filter can cause increased intake air temperature.

3. 3

   Examine the engine fan

   Confirm that the engine fan is operating correctly and providing adequate cooling to the engine and turbocharger.

4. 4

   Inspect the supercharging air circuit

   Look for any leaks, blockages, or damage in the supercharging air circuit that could affect the intake air temperature.
