SOURCE: mercury sable 2001 duratec engine DOHC I get check engine light and diagnostic code PO401". Any suggestions?

Barring any vacuum leaks, P0401 is indicative of a bad EGR valve. Hope this answers your question. Best of luck.

I have a mitsubishi diamante 01 ls im having trouble with the service engine light not wanting to go off the code is for the oxygen sensor bank 2 sensor 1 I have had two different sensors put in but none...


Hello, welcome to FixYa...your descripton indicates it's a heated 02 sensor that is setting the code...why would you not replace the correct one the first time if in fact it really does need to be repalced? ---80% of the time an 02 sensor code is set there is nothing wrong with the sensor itself, the sensor is doing it's job, it has detected a malfunction and reported it to the ECM, the ECM turned the service light on, that is what sensors do, that is how they work. I have seen motorist spend over $700 dollars on sensors and still have the same problem. On average the life of an 02 sensors is 60-80k. A good technician will know if a sensor is bad from the voltage it's drawing. You could have a dirty fuel injector or MAF sensor resulting in a rich or lean fuel mixture that caused the 02 code to be set. I hope you understand by this explanation, that even by replacing the $380 sensor there is no gurantee the problem has be repaired. A good diagnostic scan and someone that knows how to read the feedback from that scan could give you a clear cut decisive repair procedure.
I hope this helps and best of luck with the Diamante...

What size socket should I use to open the drain oil plug in a Diamante 2002 ls?


The oil drain plug on an 01 Mitsubishi Diamante LS is a 21mm. No. You can not use an adjustable wrench as the pan has a recess where the bolt goes. No it is not a 17mm. All drain plugs are on the bottom of the oil pan genius. Dont answer the questions unless you KNOW the answer.

Engine Random Misfire code PO-300


P0300 is for random miss-fire, loose or defective gas-cap, water in the fuel, damaged vacuum line, clogged fuel and/or air filter, faulty plugs and/or wires, fuel injectors. These are more common reasons, there are others but this a good start.
