Mode 5

Output of oxygen sensor data.

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: 

$81 Oxygen sensing actual value 

Output of the oxygen sensing actual value.

Display between 0 and 1.99.

In the case of decimal output, conversion factor = 0.00781

Decimal value displayed multiplied by 0.00781 gives the oxygen sensing actual value.

$82 Oxygen sensing nominal value 

Output of the oxygen sensing nominal value.

Display between 0 and 1.99.

In the case of decimal output, conversion factor = 0.00781

Decimal value displayed multiplied by 0.00781 gives the oxygen sensing nominal value.

$83 Dynamic value of the oxygen sensor 

Output of the dynamic value.

Display between 0 and 5.0.

In the case of decimal output, conversion factor = 0.0195

Decimal value displayed multiplied by 0.0195 gives the dynamic value.

$84 Oxygen sensing displacement 

Oxygen sensing displacement (current share) due to pilot control.

Display between -0.05 and 0.05.

In the case of decimal output, conversion factor = 0.00039

Offset = -128

Decimal value displayed multiplied by 0.00039 minus 128 gives the oxygen sensing displacement.

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

$01 Rich-lean threshold voltage 

Programmed fixed value: e.g. 0.575 V.

In the case of decimal output, conversion factor = 0.005

Decimal value displayed multiplied by 0.005 gives the threshold voltage.

$02 Lean-rich threshold voltage 

Programmed fixed value: e.g. 0.575 V.

In the case of decimal output, conversion factor = 0.005

Decimal value displayed multiplied by 0.005 gives the threshold voltage.

$07 Minimum voltage of oxygen sensor during the test 

Minimum: e.g. 0.000 V

Maximum: e.g. 0.480 V

Test value: e.g. 0.280 V

In the case of decimal output, conversion factor = 0.005

Decimal value displayed multiplied by 0.005 gives the threshold voltage.

$08 Maximum voltage of oxygen sensor during the test 

Minimum: e.g. 0.480 V

Maximum: e.g. 1.245 V

Test value: e.g. 0.685 V

In the case of decimal output, conversion factor = 0.005

Decimal value displayed multiplied by 0.005 gives the threshold voltage.
