The egr valve is located on top of the engine. It is close to the firewall, mounted close to the center from side to side.
The egr valve is located on the top rear of the engine. It bolts on and is easily removed.
I just replaced the EGR on my 1997 Toyota Camry 4cl and it was about $300, the downside is that I purchased a part with only a 6mo warranty and at 7 mo it went out again...
No but if there is still an EGR valve problem then its the EGR Valve switch located at the back of the motor. I replaced my EGR valve 2 times before I figured out it was the electrical switch, which had burnt up, for the egr valve. I havent had a problem with the EGR since then..
Remove it, and throttle body carbon cleaner. Make sure that the valve can be moved easily.

EGR stands for Exhaust Gas Recirculation. The purpose of the EGR system is to lower the amount of oxides of nitrogen the engine produces. The parts of the system are the vacuum actuated EGR control valve, the vacuum switching valve, and the EGR vacuum modulator assembly.
P0401 indicates problems with EGR system... It might a simple one, for instance, you just need to clean EGR pipe and valve. Or it can be more expansive one like faulty EGR valve or EGR sensor. Which one you have impossible to answer without testing the car. And you can use the professional Toyota tool to repair it, I think the Toyota it2 is a good tool for it.
according to the emissions label it does not have an EGR valve.

Contact your Toyota dealer for EGR servicing;it's easier! The EGR valve is on the lower back side of the approx. centre of the engine. You cannot see it from above. Placing your left hand between the firewall and the rear of the engine you can feel for the EGR valve. Follow the vacuum hoses down the back side of the engine until you feel the EGR valve. Forget about sight from the top view. The Toyota service manuals give the Toyota mechanics proper dignosis. Other mechanics made have other sources, I got my info from a Toyota mechanic.
If you're corolla is a 92' model then it doesn't have one. If engine ping is you're problem then good luck.
You need to replace the EGR valve. Make sure to replace the plugs too after that.
