Lambda Probe (7/15, 7/82, 7/104, 7/167, 7/285) [2019-2022]: Variants

Gasoline 

The lambda probe in the rear position in a 2-probe system is used as a lambda probe, middle, in a 3-probe system. See list below.

VEP4 

1. Lambda probe, front (7/15):

   Lambda probe, 1 (7/15). The oxygen sensor in the lambda probe, front, uses current regulation and its signal characteristic is linear. Normal operating temperature is 700 - 900 °C. The sensor does not work below 700 °C. The heating period for the lambda probe is approximately 30 - 40 s.

2. Lambda probe, middle (7/82, 7/284, 7/285):

   The oxygen sensor in the lambda probe, middle, is used while the lambda probe becomes sufficiently hot. Normal operating temperature is 300 - 900 °C. The sensor does not work below 300 °C. The heating period for the lambda probe is approximately 30 - 40 s.

3. Lambda probe, rear (7/104, 7/104, 7/167, 7/215, 7/285):

   The oxygen sensor in the lambda probe, rear, is used to regulate the catalytic converter and is voltage controlled. The sensor has a fine tuning and barely measurable effect on the regulation of the mixing ratio of air and fuel. Normal operating temperature is 300 - 900 °C. The sensor does not work below 300 °C. The heating period for the lambda probe is approximately 60 - 120 s.

2. Lambda probe, middle (7/82):

   The oxygen sensor in the lambda probe middle, is used while the lambda probe becomes sufficiently hot. Normal operating temperature is 300 - 900 °C. The sensor does not work below 300 °C. The heating period for the lambda probe is approximately 30 - 40 s.

3. Lambda probe, rear (7/82, 7/104, 7/167, 7/285):

   The oxygen sensor in the lambda probe, rear, is used to regulate the catalytic converter and is voltage controlled. The sensor has a fine tuning and barely measurable effect on the regulation of the mixing ratio of air and fuel. Normal operating temperature is 300 - 900 °C. The sensor does not work below 300 °C. The heating period for the lambda probe is approximately 60 - 120 s.

Diesel 

1. Lambda probe, front (7/15):

   Normal operating temperature is between 700 - 900 °C. The sensor does not work below 700 °C. The heating period for lambda probe 1 is approximately 30 to 40 s.

2. Lambda probe, rear (7/82):

   Normal operating temperature is between 300 - 900 °C. The sensor does not work below 300 °C. The heating period for the lambda probe 2 is approximately 30 - 40 s.
