Egr Temp Sensor: Check Engine Light Cel

[dfila]

I just got a CEL and my local mechanic said it coded to a possible EGR temp sensor. He said they really aren't needed. but my problem is to get the check engine light off. The car runs good. Is there any way to bypass the

computer code?

Maybe the contacts are dirty. Where is the EGR temp sensor? Easy to replace? costly?

Do I have to resort to taking it to a Lexus Dealer or can I do some things myself?

Thanks,

Don ;)

I had the same light and just changed my temp sensor this past weekend.

No dice. It did not fix it.

So, there are a couple of other things that need to be tested.

But, you probably need to test yours first to see if it will help.

How mechanical are you? Do you know what an EGR valve looks like?

If not, I can take a picture and guide you through testing yours.

Do you have an ohm meter?

Hi Tom,

Sorry for the delay, but summer was a busy time and since my car was running well I didn't do much with it.

At any rate, here is the new information. I took it to the Lexus dealership and the EGR was plugged. They cleaned it out and the car did run (even better). However, the EGR code 71 (temp sensor code came on.)

They said my EGR had no temp sensor so I would need to spend 225 for a new EGR valve and 177 for a new temp sensor which is attached to the EGR valve.

Here's what I think. Early in the summer I had to have new Computer installed. I think this new computer is looking for a temp sesor, but my car does not have one so therefore I get the code 71.

Now, Is there any way for the computer to be fooled so that it thinks that my car has a temp sensor?

Could I buy a kit and block the EGR altogether and then fool the computer?

I think I am going to post a new thread and try to get multilpe ideas with regards to this problem.

Thanks,

Don
