Had it for months but car runs find. Went to a mechanic and he said it was
the gas cap that wasn't screwed on tight and charged the wife $150 but the
check engine light came back a few weeks afterward. I finally purchase a
OBD2 reader and found the P0402 message. How do I fix this myself? Is it the
same problem components as P0401?

Both codes point to the EGR (exhaust gas recirculating) system. You will
have to determine what component(s) are bad.

P0402 Exhaust Gas Recirculation Excessive Flow Detected is the opposite
problem from P0401, which is Exhaust Gas Recirculation Insufficient Flow
Detected but they both relate to the EGR valve.

You can try removing the EGR valve and tube and see if there is a lot of
carbon buildup inside that is preventing the valve from closing. You may be
able to dig out some of the carbon and get it working again.

Another possibility is that the vacuum control system for the EGR valve is
not working properly, and yet another possibility is that the there is a
problem with the EGR valve position sensor. If cleaning out the valve
doesn't work, you can access the factory manuals at techinfo.toyota.com for
$10/day to do the diagnosis.

Good luck!

This seems to be a common code! We see it all the time.

I removed and replaced the vacuum hoses on my '95 Tercel and the code
went away...after 2 years!

I kind of think that the EGR is jammed open, but the OP didn't complain
about rough idling, which might accompany an EGR that is not closing.
