whats up guys....so my CEL has been on for years...car has run fine.. i took it to a mechanic in november and he said a rear o2 sensor needed to be replaced along with the ERG valve. i never did the repairs at that point.

well now i need the CEL off ASAP to pass emissions. i took the car to autozone today to check the CEL....it didnt throw any codes at all...the autozone person said the CEL light must be on by mistake or the CEL light is malfuctioning...

does this sound right? should i take the car to a different autozone and check again??

never seen a CEL on and it not throw any codes, because that means it has a code stored when it is on. Did autozone reset the cel and it come back on?

did you check to see that the gas cap is on correctly?

I didn't think about the gas cap since the OP said it had been on for awhile and figured he had already put gas in the vehicle and taken the cap off and back on a few times but yes the cap can definitely cause the CEL to come on and may not throw a code

i would definitely reset the ecu and wait and see if the CEL comes back on and then try to get another reading

JORTS

its not the gas cap...how do you reset the ECU? unhook the battery? how long does it take for the check engine light take to come back on if there is a problem after you reset the ECU?

thanks guys

Autozone should have been able to do that while you were there. With my scanner you just press and hold a button in to reset it. Unhooking the battery for a certain amount of time may do it as well. I think within 30 miles it should come back on with most CEL (at least if they are going to inspect it, they want you to drive it 30 miles after a reset) some may not take as long as others and some may take longer. I don't think there is a predetermined amount of time before it comes back on

definitely reset the ECU and see if it comes back

so i went to a different autozone today and they got it to throw codes immeadately.

as always, need your help guys
P1298: electric load detector (ELD) circuit high input probably cause/ poor electrical connection/ failed ELD

P0138: Secondary H02s12 (heated oxygen sensor- bank 1 sensor 3) circuit high voltage; short circuit condition/ fuel system faulty- rich condition/ faulty sensor

P1491
ERG Left insufficient detected probably cause/ poor electrical connection/ failed ERG valve

my best friends mom works for an auto parts distributer...so i am going to go ahead and order a new ERG valve and 02 sensor (i had a mechanic tell me to replace both of these back in November so i know they are bad)

however, i dont know what to do with the first code:P1298
do you guys know what this is?

The ELD is essentially a current transformer that monitors the amount of current draw the car is pulling from the battery. This amount varies from time to time depending on what you have turned on (various electrical devices). The ELD will output .1 - 4.8 volts to the ECU. This reference voltage is what tells the ECU to increase or decrease the field strength in the alternator, which in turn bumps up the output of the alternator.

Thanks. I read up on it on google. But I want to know if anyone with a CL has had this code and if so how did you get it off? Did u have to replace this ELD itself? I saw some trouble shooting guides and will have a mechanic try that I guess

JORTS

The car is at the mechanic now getting the ERG and O2 sensor changed. I am hoping the ELD code takes car of itself when we reset the CEL.

Quick question; I had a amp and sub in the car for a long time. I took the amp and sub out about 2 yes ago. The CEL has been on for over 2 yrs. Could the amp have caused the ELD code from when it was connected years ago? I am hoping this was the problem and once we reset the CEL it will be back off for good

In just from my own understanding, sounds like you either have a bad wire, connection is probably loose, or something is giving it resistance on the ground side of that detector. Could be wrong, but that's just how I'm understanding it.
