2000 Honda Accord VTEC error codes
My son has his check engine light on and after posting the codes on the Accord site I have discovered that the problems could be caused by several items. The car has a VTEC 4 cyclinder.
My error codes are P0401, P0450 & P0453. Here is what one poster left for me but after talking to the Honda parts dept at Classic in Round Rock, Tx I am guessing I need to take this thing somewhere.
Do you Central Texas guys know of a good mechanic or dealership to use?
P0401 Solutions:
In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
* Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
* Clean out the EGR valve and/or tubing to remove deposits
* Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
* Replace the DPFE sensor (with a good quality / OEM one)
* Replace the EGR valve
P0450 Solutions:
replacing evap sensor switch and making sure that the charcoal canister that the sensor is attached to is not damaged because that would also be a possible culprit
P0453 Solutions:
make sure the fuel cap is on tight and that it is the correct type or replace the fuel cap itself
