Testing steps:

  • Remove the vacuum hose on the top of the EGR valve and plug it.
  • Connect a short hose to the EGR valve.
  • Start the car.
  • Now **** on the hose, or use an appropriate tool to apply suction to the line
  • this will open the EGR valve the engine should stumble and try to die.
    If it does the EGR valve is working.
There is an "Exhaust gas manifold pressure sensor" that measures the exhaust gas flow to the EGR valve. The problem is the sensor itself becomes clogged with exhaust carbon and gives the computer a fixed false reading, the computer in turn sends too much vacuum to the EGR valve and the engine runs rough, surges and may die.

Fuel cal-pak incorrect or missing


52 is a faulty knock sensor signal. The connection there may be loose or broken. 71 is an EGR temperature signal fault. Again the connection may be loose, or the EGR temp sensor faulty, or the EGR vacuum switching valve faulty.

P0171 code problems


That is trouble in the Exhaust Gas Recirculation system (EGR). It could be

- faulty EGR gas temp sensor
- faulty vacuum valve or circuit
- faulty EGR valve
- disconnected or blocked EGR hose

Details here, p390

No vacuum


That would indicate a likely failure in the EGR vacuum modulator, or the EGR vacuum service valve (VSV). The latter is electrically operated by a solenoid, and can be tested that way. When they fail in Toyotas they sometimes fail when hot, but test OK when cold. See here, p152

94 camry engine light on, code 71, how do i fix it


Go to Autozone and have your current EGR Valve, removed from the car, tested and they will determine if it is defective. They tested 2 for me, and neither was a replace, just a clean and they worked great. If they don't have a brand that suits your wants, just test it, then buy the new somewhere else, no commitment to buy.
The most common problem with these EGR valves is they get plugged up from carbon build up. Best way to test it is with a little hand held vacuum pump. Hook it up to the EGR valve and with the engine running at idle and squeeze the vacc pump handle a couple times to open the EGR valve. That should kill the engine. If it dosent, the EGR valve is probably plugged up. At that point you'll have to take it off and clean the carbon out. Even if you have your mechanic check into it, it shouldnt be that expensive to remove it and clean it out or replace it.

Good Luck and hope this helps: Oh and I think theres two EGR.. check the one on the bottom of the engine to. I am not sure but i think there are two EGR valves on your camery.

2000 toyota camry v6 code p0402


The egr valve on that motor has a egr positioning sensor mounted on top. The sensor goes bad and the ecu can't determine the how far the valve is opening so it opens it too much. This causes surging of the engine under light throttle application. Also as stated above the egr can stick causing rough idle. Either way if you get the valve from the dealer it will come with the sensor solving both your problems.
