ATM 3RZFE EGR Modulator for a MTM

[desertegal7]

Dear Friends,

Recently i suffers from slightly high idle about 950rpm warmed and weeks later got code P0401 egr insufficient flow.
After here and there i discovered that my factory egr modulator is faulty.

Im having a MTM 3RZ, however i only found the one from ATM 3RZ and installed it.

My question is: Shall it cause any inefficiency?

I cleared the code and now DTC showing EGR test is passed after putting the new one in.

Origanal pn for MTM 25870-75040.
What i put is from an ATM 25870-75030

BTW: my warm idle rpm still high from time to time and im suspting vaccum leak.

Regards,
Samir

Is there always a loaded rifle in your passenger foot well, aimed towards the driver? :AK47:

He's from Yemen. I'd carry a rifle too. Although I'd probably lean it the other way lol.

You should be fine. The EGR valve is just supposed to open during certain circumstances. Not very many people on here have experience with EGR systems since most North American 4Runners do not have them. If it were a drastically different part where it directed airflow differently you'd still have the check engine light. In my experience with EGR's they normally fail due to carbon buildup.
