The actual value is not o.k.Possible cause and remedy
- Check lines from component B11/4 (Coolant temperature sensor) to component N3/10 (ME-SFI [ME] control unit).
End of test
1.3. Check internal resistance of component B11/4 (Coolant temperature sensor).
Test prerequisite
- The actual value is not o.k.
Test sequence
- Switch off ignition.
- Disconnect connector at component B11/4 (Coolant temperature sensor).
- Measure resistance with multimeter between pins ( B11/4 ) 1 and ( B11/4 ) 2

- Resistor(40锟斤拷 C): [1275...1375]ohms
- Resistor(50锟斤拷 C): [850...950]ohms
- Resistor(60锟斤拷 C): [600...650]ohms
- Resistor(70锟斤拷 C): [420...460]ohms
- Resistor(80锟斤拷 C): [305...335]ohms
- Resistor(90锟斤拷 C): [220...240]ohms
- Resistor(100锟斤拷 C): [160...180]ohms
- Resistor(110锟斤拷 C): [120...140]ohms
Question

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).
