hi how are all of you doing, i found out the egr code it was the 401 code so what would i have to do

So did they test anything or just say there bad because of the code?You may only need one or both or a different problem all together.In all my years of working for dealerships i have learned to not trust someone elses diagnoses even from fellow techs at the dealers i worked at.They burned me more then once on there diagnoses and when they wernt there and the customer came back for the repair i was left holding the bag.

Iposted the trouble tree for code P0401 also are sure the egr port isnt clogged?That code is for egr insufficent flow if the port is clogged it will also set that code.

thanks alot i plan on goin to uti i just really wish i had my own scantool so many people try to trick ya

Your welcome thats what were here for scan tools are handy to have couldnt live without one in these days we live.

well my engine light went out after i changed the egr vacuum solenoid, i also changed the egr vsv. hopefully the light stays off. one thing about it my fuel hand is still drifting up and down from the actual level i think without the engine light on.

Glad to hear the light is off most likely is a bad fuel sending unit.You can test it with a multimeter.

ok how could i do that. i really appreciate everything when i get some bread on my card im gne give a donation. i been tinkering with cars since i was 12 and all of this was a challenge but i learned alot from it.

how am i suppose to check the fuel sending unit

First thing you need to do is see if you can locate a pig tail that connects to the gas tank?Also does the gauge drift on a regular basis so it can be easly tested when its acting up?

yea seem like when i hit a bump it go back to where it was at first but din it will slowly drift down

Find the connector and we will talk i will walk you thru it.

ok just gettin back online i gotta get a multimeter its gne b a while i dnt have no cash right now.

Alright no problem let me know when you get the metter and find thr pig tail off the gas tank.

ok i wanna ask you this are there any other things i could check that would cause my car to consume gas without the engine light on i think the idle is up a lil too high but i could be wrong before 1000 rpm theres a smaller thicker line and thats where it suppose to rest i think but i think its up just a tad bit instead of pointed straight at the line.

What does your car idle at in park rpm wise?Also how many miles per gallon are you getting?

ok im going to explain as good as possible ok zero has a line the idle hand is at the 3rd line from the zero line i could send a pic well its at the 3rd line.counting the zero line

Please post a pic that would really help.

its probly not that good of a pic but thats where the idle usually rest i think its at half of 1000 rpm dnt really know

this is a better one its on the third line below 1000 rpm

So about 800rpms?

i dntreally know i think it could be lower its not close to the onits like even between one and zero

yea i would say about 700 to 800 rpms.

Then that would be a normal idle.

ok what else could cause me to burn fuel is there anything else other than a malfunctioning sending unit?

So how are you figuring out your gas mileage?Also the sending unit isnt going to effect gas mileage.

i cnt really tell if i got gas or not cuz when i put gas in the fuel gauge seems like it doesnt go to the same level it usually would with the same amount of money. and it just seems like im burnin gas cuz it gets to E kinda fast even after puttin gas in it

Heres how you figure gas mileage fill the car up till the pump turns off.Then reset your trip odometer drive the car atleast 200 miles then fill the car back up till the pump turns off.Then divide the miles driven on the trip odometer by the gallons of gas it took to refill the tank.That will tell you overall gas mileage not using how much it cost to fill the tank the price of gas is up and down.Also you cant use a gas gauge working ir not to figure it out ethier.

oo ok i wanted to know something else too what would be the tell tell signs of an ecm on my car beginning to malfunction?

Thats a tough question because all ecms dont always fail in the same way.What i do is rule everything else out and suspect the ecm last.

ok

ok today the engine light came back on the parts i exchanged on my egr valve were from da junkyard that may be the cause but i seriously believe they gave me a bogus code im gne get a scantool for my car on the 1st of the month and get the codes myself.

Alright let me know the exact code numbers when you ge them.

yesterday evening a friend of mine that owns a shop scanned my car with a snap on scantool n he said the computer wasnt communicating with the scantool. what do you think that was? also i wanted to know what scantool i could get to scan my car

I would think something was wrong with the guys scan tool since pep boys was able to read your codes.So do you have a 16 pin connector for your scan tool to hook up?

yea i think he tried to plug it in underneath the steering column doe

So is your connector for reading codes 16 pin?

i think so i dnt know im gne check i know its underneath the steering column and i got a data link connector under the hood.

Iam not real familar with aftermarket scan tools i mostly used the Tech2 and tech1 scan tool all the gm dealers used.I have the actron obd1 and obd2 scan tool with the domestic obd1 connectors and universal obd2 connector.It only does domestic obd1 cars iam not real impressed with it But it reads codes on the engine with some live data and reads transmission codes.

yea i think its gonna have to be obd 1 and 2 i think my system is obd1 just a matter of gettin the best tool i can get for my bucks without payin alot i was thinking about harbor frieght.com
