Code P0401 1998 Toyota Camry

I have a 1998 Toyota Camry that had not been driven in several months. When I finally try to start it to have it inspected the battery was DEAD. Replaced battery. Took car for state inspection and it failed. Person at inspection place asked if I had had battery replaced and how much I have driven car. Told them just replaced battery and drove car to them. They told me to drive the car for about 60 miles so it can "reset itself".

When I left and drove car, check engine light came on! Took to Auto Zone and test results came back with a Code P0401. Auto Zone cleared the Check Engine Light. Five miles later it was back on!

This car has over 150,000 miles on it. It runs great!

How expensive is it to change the EGR value? I do not drive this car much at all; it sits outside. I have 15 days (8 now) to get whatever is wrong repaired. Help!

Single Woman with no mechanic skills!!!!

    The P0401 code keeps returning after I reset it. I changed the EGR valve and the EGR modulator. The light stayed out about 50 miles after I changed the egr modulator. What else should I do?

I'm assuming that it is a four cyl.The p0401 code is for insufficient egr flow.Most of the time it is the egr vsv valve (vsv means vacuum switching valve)which is what controls the vacuum to the egr valve to open it.It is kind of hard to get to as it is on the block under the head on the back side.If you follow the hose from the egr valve it goes to the vsv.I have also seen mice eat holes in the vacuum line which would also give you problems.I hope this help and let me know if you have anymore questions

The light may be , but not the starting issue. Sounds to me like this needs a complete tune up the way your describing the starting issue. The engine light usually do stay on while a car is starting, they are programmed to go off 10-15 sec after the car starts. This is simply the computer going thru all the sensors.

Ive worked in a Toyota dealership for the past 11 years and yes I have seen oil filters work there way loose and vibrated off, but you are right, not usually after 4 months of driving. It could have happend if it was loose origanally and then it finally worked its way off. idk its hard to tell- but ill tell you one thing usually when this happens it it with an aftermarket oil filter and not a genuine Toyota filter. and 08 Camry motors rarley blow and dont burn or leak oil so the filter over time had to be the only way for it to loose oil. Im not trying to take the dealers side cause i work at one- all im saying is that it is possibe.
