Legend
B16 (Right temperature sensor upstream of NOx storage catalytic converter)
B16/1 (Left temperature sensor upstream of NOx storage catalytic converter)
Test prerequisite
The actual value is not OK.
Test procedure
Ignition OFF
Measure direct voltage with multimeter between socket [F.23] 119 of the 126-pole socket box tester and socket [F.35] 5 of the 35-pole socket box tester.
Ignition ON
Status of associated actual value
Observation Exhaust temperature in right NOx storage catalytic converter: communication with ECU required.
Specified values





Question
Are the measured values OK?
