Yeah its worth a try, sometimes cleaning it works, sometimes it doesnt. In the 5 years i've owned my car i've had to clean the EGR twice.Mustang5L5 said:Forgot to add that i already had tried to clean it and lube it up but still had the code. That's when i decided to just replace it
Oops your right, i just checked my records and its a 34 i've had a few times, sorry.Zee said:Code 32 means the sensor voltage is lower than expected for a closed valve (less than 0.29 volts). A dirty EGR valve will not cause this code.
It could be a mechanical problem with the way the sensor is connected to the valve, but is most likely caused by a bad sensor.
A dirty EGR valve will not seat fully, causing sensor voltage to increase. This will generate a code 34.
Not having vacuum applied to the valve is probably what is causing the code. When the eec trys to open the valve, it expects a higher reading to indicate that the valve opened successfully. If no opening, you get the error code. The sensor is there to monitor the function of the EGR valve. If it isn't functioning (no vacuum), you will get error codes.C.
