Do you have an odd smell in the interior compartment? This could be due to the egr being damaged from debris from the road. Hire a professional to do it or go to a car parts store and get the motors repair manual or similar.

Code p0405


You need to diagnose the EGR System
Not replace parts in hope of getting it right
Codes only indicate an Emissions Malfunction
or Fault, thus the code
Codes & trouble charts are used to then component test
Google the code & study the problem
There are many EGR Codes--- study yours ,as it pertains
to your vehicle & engine package

Getting P0405 , P0300 , P2670 code what is that


P0405 means Exhaust Gas Recirculation Sensor A Circuit Low. It may caused by Short to ground in EGR signal or Reference circuits or voltage in EGR ground or signal circuits;Bad EGR valve; or Bad PCM wiring issues due to chafing or loose terminals.
P0300 is Random/Multiple Cylinder Misfire Detected. It may be something wrong with spark plugs or wires,coil,oxygen sensor,fuel injector,etc.
As for P2670, it seems for the Actuator Supply Voltage "B" Circuit Low.

2005 Chevrolet Equinox These are the codes that show up when we place the Scanner P0068, P0108, P0300, P0405, P0443 Can someone please help me with this? Thanks in advance.


P0108....Manifold Absolute Pressure/Barometric Pressure Circuit High Input


P0300....Random/Multiple Cylinder Misfire Detected


P0400....Exhaust Gas Recirculation Flow


P0433....Heated Catalyst Efficiency Below Threshold (Bank 2)

Do not have a listing for the 0068 reading as it doesnt exist in my list ,looking at this i would block off the EGR valve with a nice home made coca cola can gasket and this should cure your problems

My Cavalier shows error code P0405, what could the problem be


P0405 - Exhaust Gas Recirculation (EGR) Position Sensor Circuit Low Voltage

You may have to replace the EGR sensor, but remove it and clean it up good to try it again first. Sometimes the pipe feeding exhaust gas up to them gets plugged.

My 2005 chevy equinox is displaying the P0405 code. I know its the egr valve. How do I fix it?


Erase the code and see if it returns. If it does, replace the valve. What engine do you have? If it is a 3.4 it should be right on top. One plug and two bolts.
