20201208· Definition: P0405 Code: Exhaust Gas Recirculation (EGR) Sensor Circuit A Low. Modern vehicles also use an EGR position sensor that monitors the open and closed position of the EGR valve. The information from the EGR position sensor is sent to the PCM, which then decides on the exhaust gas flow rate depending on how much the EGR valve opens. If the calculation of the PCM does not …

20200514· The sensor can be connected both ways in the circuit since the windings on the two sides are identical. When the gas concentration rises, so does the mutual inductance between the windings of the sensor. An increased alternating voltage will be observed in the secondary winding of the coil, which must be rectified by D1 and smoothed by C3. The sensitivity for this is set by P1. D2 is used to ...

The sensor needs a loadresistor at the output to ground. Its value could be from 2kOhm to 47kOhm. The lower the value, the less sensitive is the sensor. The higher the value, the less accurate is sensor for higher concentrations of gas. If only one specific gas is measured, the loadresistor can be calibrated by applying a known concentration of that gas. If the sensor is used to measure any ...
