Test power consumption of component 'G3/3 (Left oxygen sensor upstream of catalytic converter)'.
Test prerequisite

- The actual value is not OK.

Test procedure

- Measure direct current with multimeter between sockets [F.4] 100 and [M.73] 73 of the 126-pole socket box tester.

Note

- Perform the measurement only for a short time so that component 'G3/3 (Left oxygen sensor upstream of catalytic converter)' does not overheat.

Measured values
Enter the measured current value.
