Plausibility error between signal of temperature sensor in intake pipe and signal of outside temperature sensor (P0071)

Possible cause:

- Ambient temperature values are implausible.

Affected functions:

- Engine diagnosis

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

Test 1: Ambient temperature

1. Ambient temperature

Test 1.1: Check component B14 (Ambient temperature display temperature sensor).

Test 1.2: Check component B2/5b1 (Intake air temperature sensor).

1.1. Check component B14 (Ambient temperature display temperature sensor).

Test prerequisites

- The power supply of component N10/1 (Driver-side SAM control unit with fuse and relay module) is OK.

- Fault code 9063 is current, and (or) at least one of the relevant actual values is not OK.

Test sequence

- Detach coupling at component B14 (Ambient temperature display temperature sensor).

- Connect resistance simulator to the connector of component B14 (Ambient temperature display temperature sensor).

- Connect resistance substitution unit between sockets (B14)1 and (B14) 2

- Adjust resistance values one after another and compare them with the actual value.
