Check engine light 1996 camry

Ive replaced the EGR the VSV and the modulator and i still get the egr codes. Could it possibly be the EGR silenoid? Cant think of anything else it could be.

1999 toyota RV4 code P0401 EGR is good ,   vacuum line is good , what parts could be check.


It means that the egr valve is working, the problem is a very common one, it's the egr modulator valve and to some extent the vacuum switching valve(VSV) for the egr valve, the modulator is attached to the egr valve, remove it and if air can pass from the bottom port through it is defective, in that case replace it and see if it takes care of the problem, if the valve is ok the egr
vsv should be replaced.

Need to find location of egr sensor


A 2000 Camry with a 4cyl does not have a EGR sensor. The ECU uses the readings from the MAP and AF sensors to determine if the EGR is working.
You have a EGR VSV (vacuum switching valve) and a EGR modulator but no position sensor. Only the V6 has this.

There is a vsv (vacuum switching valve) located under the intake manifold that goes bad very often causing this code. Its hard to get to. Follow the hoses from the black plastic round valve(egr modulator) you see next to the EGR valve to find the vsv.

Code on diagnostics p0401


Code on diagnostics p0401:

What is going on?
Exhaust Gas recirculation low flow detected means that: there is vacuum problem in the EGR system - between the combustion chamber, EGR valve (mechanical - blown up diaphragm or clogged airlets/hoses) , EGR Modulator Valve (mechanical - blown up diaphragm, dirty EG/air filter or clogged airlets/hoses) and Vacuum Switching Valve ((mechanical - blown up diaphragm or clogged airlets/hoses OR electrical - VSV not properly synchronizing with the ECM, for instance).

Effects?
This causes the combustion chamber temperature to increase and produce Oxides of Nitrate (NOx) that is out of an acceptable emission range. This triggers the Malfunction Light (check engine light) to stay on (after a couple of driving cycles)!
Solution: Focus on EGR airways (hoses...) and organs (EGR valve, EGR Modulator, VSV), clean, check or replace the defected one. VSV seems to be criticale as it plays electrical & mechanical function. Once the repair is done, Clear the P0401 code using an OBII scanner.
