Hello,

My Camry '97 just failed inspection. It is code P0401. 'Exhaust Gas
Recirculation Flow Insufficient Detected.' Would you please give me your
recommendations.

Thanks,

How many miles are on the car? With the engine idling, apply vacuum to the
EGR valve and see if the engine starts to idle roughly or start to die. If
that happens, check the EGR position sensor. If the engine does not start
to die, check the EGR tube for blockage. Most likely, the EGR tube is
blocked with carbon buildup. If that is the case, you can try to dig out
some of the carbon or replace the EGR valve and tube.

Follow Ray's advice and check the EGR, but also, I had a Tercel with this
same problem and had to replace a couple hoses...

The car has 130,000 miles. Is the EGR tube the metal tube?

inspectors should be able to tell him what the prob usually is

At 130,000 miles, there is a fairly good possibility that the EGR tube is
blocked, especially if the car has mostly city miles. The EGR tube is the
metal tube that is attached to the EGR valve.

In New Jersey, for one example, it is as Mark says exactly.

I am in Texas. The inspection report failed, because of code P0401. And,
the 'Check Engine Light' has been on for some time. I should not have taken
the car for inspection before taking care of the Engine Light. How is the
tube detached in order to clean it? Are they other parts to clean? If it
is a blocked tube, how deep down do I need to go, while clearing it?
Thanks.
