Check engine and anti-slip light on

Today, for the third time in two months, my check engine and VSC lights came on. The two times prior the code has been P04556 (minor emissions leak). I replaced the gas cap, but still comes on. I haven't figured out how the VSC light plays into this. Anyone have any insight into possible causes? I'm getting tired of going to O'reilly's to get the code verified and reset. The dealership wants $125 to hook it up and diagnose the problem. I can only imagine the cost to repair. Help!

 

Well if it’s any consolation my VSC light has been on for 7 years

 

When the code is reset does the VSC light go out? Should be normal for the 2 to come on together.

Kind of anal about not having fault lights on my instruments cluster.

 

It's extremely common for multiple lights to come on for a simple code, you have some sort of vacuum leak somewhere past finding someone with a smoke machine going to be a little hard to find

 

Need a new clock spring mechanism... free from dealer thanks to TSB ...

 

Maybe find an independent mechanic? He won't charge you to diagnose if you have him fix it. Disconnecting the battery will also reset the light, but you’ll still have to actually fix it.

 

When they are reset, both lights go out. Thanks Sandman for the link. I did a search, but didn't come up with that thread. So, should I take it to have it diagnosed, then get my own parts?

 

I had the clock spring replaced already under TSB, P. Steve.

 

Me, too. Edit: I am growing quite fond of the light; knowing it’ll be waiting for me

 

Then pay what it takes to get some answers from someone who makes a living fixing evap problems

 

Code reader from Autozone for 79.99 well worth it for the same problem.

 

Did you put a new FACTORY cap on it or one from like Autozone.

 

Started my Tacoma and same lights came you spoke of came on? I drove it down the road pulled over, turned off truck, restarted, and lights did not come back on. Go figure????
