P0405 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) sensor has went below its specification range. A short to ground of the sensor input to the ECM.
What does fault code P0405 mean?
Exhaust Gas Recirculation Sensor A Circuit
What does OBD-II fault code P0405 mean? OBD-II Code P0405 is defined as a Exhaust Gas Recirculation Sensor A Circuit Low. NOx gases, which are a leading cause of acid rain and in some people, respiratory problems, are formed when the engine combustion temperatures become too high (2500° F).
What does exhaust gas recirculation sensor A circuit low mean?
Diagnostic trouble code (DTC) P0405 stands for “Exhaust Gas Recirculation Sensor A Circuit Low.” It denotes that the readings coming from the EGR valve position sensor show lower voltage levels than normal. As its name implies, the EGR position sensor detects the position of the EGR valve.
Where is the exhaust gas recirculation sensor?
The EGR temperature sensor is usually mounted in the exhaust manifold or mounted near the EGR valve.
How do you fix an exhaust gas recirculation sensor A circuit high?
Zitat von Youtube: First carefully remove the egr valve from your car. Turn the egr valve upside down and fill it up with the wd-40. Cleaner. Let it soak for five hours for the solvent to get rid of all the carbon.
How do I fix error code P0405?
What repairs can fix the P0405 code?
- Replacing the EGR position sensor after the wiring is checked to be okay.
- Repairing the wiring short to the EGR position sensor or connector signal return.
- Repairing an open in the voltage reference to the EGR sensor.
How do you fix an exhaust gas recirculation circuit malfunction?

How much does it cost to replace the EGR sensor?
The average cost of replacing the EGR valve in your vehicle is anywhere from $250 to $350 on average, depending on your vehicle’s year, make, and model as well as the type of system it has. The cost of parts will be somewhere around $190 to $270, while the cost of labor will be anywhere from $60 to $80.
Which of these engine concerns may be caused by a stuck open exhaust gas recirculation valve?
If the EGR valve is stuck in the open position, the vehicle will experience a rough idle or frequently stall. If the valve is not completely stuck open but never achieves a tight seal when it closes, the engine can “miss” or shudder because of the improper mixture of the combustion elements.
