The difference between the current measurement and the most recent measurement of the exhaust gas temperature from component B19 (Catalytic converter temperature sensor) is too great.


Possible cause:

- B19 (Catalytic converter temperature sensor)
Affected functions:

- Power generation

-------------------------------------------------

Test 1: Check component B19 (TWC temperature sensor).

1. Check component B19 (TWC temperature sensor).
Plausibility check of component 'B19 (Catalytic converter temperature sensor)'
Test sequence :In the following test, the engine speed is raised to check the temperature sensor.Specified value

- The temperature difference between components B19/11 (Temperature sensor upstream of turbocharger), B19 (TWC temperature sensor) and B19/9 (Temperature sensor upstream of diesel particulate filter) must not be greater than 60° C.
Start engine.Continue with button F2

Warning!Communication with ECU required.
