Photo of EGR carnage

Overheated it somehow I guess, yikes! Any thoughts on $$$ to repair?!

 

[rc51kid]

Yes, remove it!

What is the electrical fire hazard behind it on the firewall?

 

[Funner]

That melted mess is the modulator for the EGR. The EGR is the metal spaceship to the right of the melted plastic.

Is that the engine that was replaced for you about a year ago ? Modulator looks like It was torched.!? I thought the one that blew was a S/C engine you may have same avatar. Sorry If I'm mistaken..!

 

[beachcomberspi]

This is the same engine that was rebuilt a year ago

Not uncommon

Although, yours is the worst I've seen

Melted EGR Vacuum Modulator

 

[Output Shaft]

The EGR modulator can melt if it's internal diaphragm develops a leak. When that happens, blazing hot exhaust gas is constantly leaking through the plastic modulator. A new modulator won't melt.

according to Beno, the EGR modulator is 85$ in a quote he sent me while I am diagnosing my EGR faults

 

[DARKNESS]

That's impressive. How did you notice it? Did the car start acting weird or did it explode while you were driving?

I usually get my parts here. EGR MODULATOR | Genuine Toyota | 25870-46010

They're showing $78 shipped to me in Denver. Pick up a foot (or meter) of vacuum hose as well.

Eh spend the extra $7 and support a guy that works hard for our community.

It was like I had a parachute out the back. And then sputtering, jerky behavior to get her home. Wouldn't go over 40

New modulator didn't change a thing. I got it over to Toyota and they think it's the ECU not "accepting the SCharger. I told him it"s run great generally for three full years. What say ye?

How much is an ECU?

Frustrated in Austin!

 

[beachcomberspi]

I forgot to say the OBD2 port won't accept a reader. It's just blank.

 

[Rivman1243]

Check your fuses

 

[beachcomberspi]

So the ECU didn't fix it but it read an error code from the MAF. One MAF later it runs like a champ! Unfortunately it wasn't my MAF so I guess I'll post in the parts needed thread.

What did you do to get your obd2 port working?
