94toy4x4fever

I have a 94 toy pickup with the famous 22re. I put a new engine in it less that 3 months ago and have been having problems ever since. I drove it for the break in process (500 miles) and it threw a check engine light. So I got the code and it was the EGR code. I took it to the toyota dealer here in town and they told me that the EGR is good it just doesent want to close. What sould I do? Also the truck has been pinging with the timing at 5* with the jumper. Even with high octane gas. Old owner cut the cat out and installed a flowmaster. Any Ideas on what is going on here. All info will help a bunch. Thanks guys

Mabye fuel injectors?
EGR?
o2 sensors?

Im running ngk R plugs dont know if there to hot or what?

how can it be good if it doesnt want to close?

TOYOTA 1

lol thats what i was thinking!

LTrunner

if your egr won't close than it bad

94toy4x4fever

well thoes guys at toyota must not know what there talkin about. They told me that it would open but not close. Kinda seems weird that they wernt like hey you need a new one. Being that toyota loves to rape people lol So you guys thing I should bust ot the cash for a new egr?

94toy4x4fever

or could it be the egr temp sensor?

I don't think it would be the sensor!

It sounds like the egr is bad since it is not closing,

It could be the sensor, but i thought the sensor was more for having the egr open.

Does the EGR close at all, even when the truck is off? Or is it stuck open?

yo lewiston what about hitting a junkyard!
can you test the egr witha multimeter???
do you have the link to the fsm?? its at teh top of the 86-95 truck section

dont get used sensors...waste of money i know...just get a new one.. i bet it fixes the problem
and yes the egr should open and close freely..it depends on how much vacume the enigne makes...the higher the rmps the more vacume,the more egr opens..so if it's stuck all the way open it's not following the correct amount of exhaust gas at lower rpms

Im new to the whole egr stuff! Im not sure how to test it. A guy at the toyota dealership just told me thats what the problem. So tell me how I can check this thing out!

904_runner

One way to test it is to pull a vacuum hose off near the egr. One that has suction. Then take the top hose off the egr and stick the other vaccuum hose on it. If its working, the vaccuum from the line will make the egr open and the engine should stumble.

here' how you fix it...right down your VIN #...go to toyota and tell them u need a new egr for this truck, give them the VIN, then instaull siad new egr

So I should buy a new egr and the gas temp sensor and the modulater

here is a link to the factory service manual... its gonna be your friend..

yeah it might not be the best to buy used sensors...

904_runner

Its up to you!

Yea i made the mistake of buying a used sensor(didn't work) till i figured out how to bypass the sensor!

I ended up going to NAPA and getting an actual TOYOTA Egr valve for $75 bucks. It turned out i didn't need it.

You could buy an egr valve, reset the code and drive it around and if the CEL doesn't come back on then the egr was the problem, if it does come back on, then you could replace the sensor, and repeat the process.

That is of course, if you have money to spend

Im going to try the vacuum line thing right now to see what happens! SO I just need to fid one that has vaccum and put it on the one coming out of the egr?

904_runner

Yup, That will let you know if the Egr is working if it stumbles, if it does not stumble then its the EGR most likely.

94toy4x4fever

ok so I just went out and put a vaccum line that had vaccum and put it on the top of the egr and it did nothing! those guys at toyota suck

94toy4x4fever

you can here a thumping sound when you take the hoes off that has vaccum
