These fault codes are stored if the measured value of the intake air temperature sensor (component B2/5b1) is implausible.
During the plausibility of intake air temperature procedure the actual value of intake air temperature (component B2/5b1) and coolant temperature
(component B11/4) is compared at engine cold start. A fault code will be stored when these two temperature values are not close enough to each other.
Please check component B11/4 (coolant temperature sensor) for proper operation.
Note:
Fault Code 1101, 1102, 1103, 1104, 1599, 1600, 2069, 2070 are related to the Ambient temperature display temperature sensor (component B14).
