Lambda Probe Gas Mixture Control - Inlet (MHK500840A)

This is the inlet lambda probe for mixture control, made by Autotec. It measures the oxygen in the exhaust gases so that the engine control unit can adjust the air and fuel mixture. It is usually replaced when it fails, causing a warning light or higher consumption.
