Low flow Egr check engine light

Here is the info on how to do drive cycle successfully...


How to Perform Basic Drive Cycle

run the fault codes to ensure that the EGR valve is faulty. Engine lights to not always come on unless there is something drastic going on with the engine /gearbox so that you can stop the car before damage is done.

EGR - low flow , check passages . EGR reduces NOx.
Exhaust gas recirculation

PO402--EGR Flow Excessive Detected

There are other components besides the
egr valve in that sytem,so you got things to
diagnose there you skipped over

PO443---Evap Control System Canister Purge

Valve Circuit Malfunction


PO1409--EGR Vacuum Regulator Solenoid
Circuit Malfuntion


PO420 & PO430--Catalyst System Efficiency
Below Threshold---Basically worn out exhaust
converters you will need to replace


Advice--take to a repair shop & go thru the entire
car & resolve ALL Issues

Check all vacuum lines to the EGR valve, the EGR valve is between the intake and the exhaust, EGR stands for Exhaust Gas Recirulator valve. It must be able to flow properly in order to pass emissions anyway if they do a smog test.

You've probably fixed this by now. I had the same problem and it wouldn't pass the smog check. I thought I'd have to replace the EGR valve but now know that would have not solved the problem.
The solution was to remove the EGR valve, plug the rear hole and use some carb cleaner down the other hole. I'd get two cans. I sprayed a bunch of liquid in the hole but it just filled up. Had my wife come out and rev the engine for a bit. Finally, the liquid got sucked into the port and I sprayed an entire can in while she kept the engine RPM up. Bolted the EGR valve back on, took it to the Smog check place and it passed with flying colors.

you should just sell it

the 5vzfe engine it does not have an EGR

You block it off before the valve on the metal pipe that runs to the EGR valve. The problem is that when you go to get it smogged you have to replace the EGR or it will not pass smog

well nanifold is part of the emission and the egr repair both and save time re e testing it! you want it to go through first time with the above wrong it wont pass!!
