How to fix Scania EMO fault code 273?

  1. Rectify any other fault codes for the temperature sensor in the intake manifold.
  2. Check the temperature sensor in the intake manifold, its harness-to-component connectors and cable harness.
  3. Check that the temperature sensor in the intake manifold is fitted correctly.
  4. Renew the temperature sensor in the intake manifold.
  5. Note: Always carry out a default setting of the adaptation values for mass flow sensor T126 if the mass flow sensor has been renewed, or if leakage in the engine intake system has been rectified.
