My 2006 acura tl engine emission indicator gauge came on today and when in park or idling the car is vibrating slightly.

Any suggestions and possible cost before I take into dealership. Hate to walk in with no clue since extended warranty ended April this year :-(

I did get gas yesterday and went out last night and screwed the gas cap on until it click.

Fyi the light went off earlier today and did not come back on.

Thank you

I googled and found the 61-1 is related to battery except I got a new battery 3/13

I looked up the codes given, but can someone tell me what they "really" mean? I'm a woman and don't want the dealership to take FULL advantage of the situation

The EGR one, if it comes back is an easy fix.

Most likely it'd just mean cleaning the EGR valve and checking the passage, which means like a $5 can of berryman's B12 Chemtool carb cleaner (best stuff I've ever used to clean deposits) and about 30 minutes worth of work. There's only 2 bolts holding it on.

Does your car exhibit any other problems? If the EGR were stuck shut I'd imagine that light would come on but you wouldn't really have any performance problems, people block it off all of the time.

If it were stuck open then you'd have a really rough idle, I had that code on my car just a few weeks ago and did a thread here:

The pressure switches are also inexpensive and an easy fix. Here's a thread on that as well:

I'd think if one of them was faulty it'd probably set the P0700 code along with it since there's a problem with the trans (one of the switches), that's my guess though.

I'd try fixing those two problems, resetting the computer by disconnecting the battery for about 30 minutes, then reconnect it and start the car. Let it idle for 10-15 minutes with the AC, Radio, etc all off and see if your check engine light comes back on.

The EGR valve itself could go bad as well, I've never seen one fail though they usually just get dirty and stick. There are some tests to verify if the valve itself is bad, just requires a digital multimeter .. more than likely its just dirty though.

Did your check engine light come back on after it went away?

Therapyacura

No it did not. Also, I did hit a plate in the road about 2 hours before filling my gas.

Noticed after filling tank the car vibrated a bit while in park and idling.

Not sure if related, but once I screwed my gas cap on the light went away and no more vibration??
