Mode 5

Data Output with a Scan Tool

The output of data relevant to OBD from the control modules was stipulated by law for the USA. It is described in SAE J 1979.

Data output is subdivided into different modes.

Mode 5
Output of oxygen sensor data.

Mode 5
In Mode 5, the values of the last oxygen sensor test carried out (test identification TID) can be read out for every oxygen sensor with its nominal values.







For the oxygen sensors ahead of the TWC (bank 1/2, sensor 1), the following TIDs are supported:

$01 Rich-lean threshold voltage
Programmed fixed value. e.g. 0.430 V

$02 Lean-rich threshold voltage
Programmed fixed value. e.g. 0.430 V

$07 Minimum voltage of oxygen sensor during the test

Minimum: e.g. 0.025 V
Maximum: e.g. 0.385 V
Test value: e.g. 0.280 V

The specified range within which the voltage must lie and the actual value are displayed.

$08 Maximum voltage of oxygen sensor during the test

Minimum: e.g. 0.475 V
Maximum: e.g. 0.790 V
Test value: e.g. 0.685 V

The specified range within which the voltage must lie and the actual value are displayed.

$09 Time between two transitions

Minimum: e.g. 0.00 s
Maximum: e.g. 1.20 s
Test value: e.g. 0.36 s

The specified range within which the time must lie and the actual value are displayed.







$30 Shift in oxygen sensor characteristic towards rich

Minimum: e.g. 0.00 s
Maximum: e.g. 1.20 s
Test value: e.g. 0.10 s

The specified range within which the time must lie and the actual value are displayed.

$31 Shift in oxygen sensor characteristic towards lean

Minimum: e.g. 0.00 s
Maximum: e.g. 1.20 s
Test value: e.g. 0.10 s

The specified range within which the time must lie and the actual value are displayed.

$32 Averaged period

Minimum: e.g. 0.32 s
Maximum: e.g. 0.40 s
Test value: e.g. 0.36 s

The specified range within which the time must lie and the actual value are displayed.

NOTE: For the oxygen sensors after the TWC (bank 1/2, sensor 2), only the TIDs $01 to $08 are supported.
