I used jumper wires on my control module to give me error codes on my car and it said there was something wrong with my Egr sensor lift (code 12) . After that i replaced the old egr with a new one and I still have the engine check light on. What is the problem? I check the error codes and it still said that i have a egr sensor lift problem.

 

you have to reset the EDU to clear the codes

 

 

ohhh i forgot to tell you how to reset the ECU

Next time you have a problem don't bother messing with all the jumper wires and stuff. Most Autozone's and Advance Auto Parts now have a FREE engine code scanning service and have the auto x-ray machine to do it with. Thats where I take my car because they can scan it with the machine and then clear the codes and I can then buy the parts I need all at the same time !!

 

i have my own snap on scanner.

 

Is there any other way to clear the codes? like removing the ecu and putting it back on?

 

Unplug the battery. Don't forget to write down your preset stations in your radio. If you have a 5th gen, you can pull the 7.5 amp fuse in the underhood fuse box (easier, but you will still lose your station presets).

i did do that and i still have the engine check light on. What is wrong?

 

Well, here is the thing. Code 12 represents several possible problems:

-EGR valve lift insufficient detected, probable causes: EGR valve, EGR valve lift sensor circuit, EGR control solenoid valve, EGR control solenoid valve circuit, EGR line, bad ecu.

-EGR valve lift sensor high voltage, probable causes: EGR valve, EGR valve lift sensor circuit, bad ecu.

By just running out and replacing the EGR valve, you kind of jumped the gun. The Helm manual has like 4-5 pages of troubleshooting steps to narrow down the root cause of the problem.

 

Yeah i did jump the gun on getting the egr valve, but now i don't know how to check my egr system. I have a chilton prelude manual, but it is not so descriptive on some of the procedures. I guess i have to try it out to see. THanks shark.

 

Man, I had a chilton manual... those things are bad ***... 10 years worht of 2 different cars (prelude and accord) in about 100 pages... WHAT A CROCK OF ****... I finally got some sense in me... KINDA... The policeman wasnt thrilled about the fire in th middle of the road though .... He warned me thank god, but hell... IT HAD TO BURN...

 

Where can i get a helm manual for my car? THe only manual i have and can find is the chilton's manual.

is it the training manuals or what?
cause the training ones seem to be broken down into mad specific parts, is there a general one in there, and under what.....?

 

go to a honda dealership and get the Prelude Shop manual for like $45-$60

 

No, you just want the service manual. Some dealerships carry the Helm or will order it for you. Others will just direct you to the Helm website to order it yourself.
