    As the title says, the truck has 450 miles on it and the check engine light, in conjunction with the slip indicator light, are now on. I don't have a code machine to check the codes but I have an appointment with the dealership tomorrow morning.

    The only thing I can think of is something went wrong with either the TRD cold air intake I installed over the weekend, or the wicked flow muffler I had welden on late last week.

    So frustrating. No one wants to take in a new vehicle for any reason :(

    Think I am on the right track with the light? After some searching on the web, it seems that when the CEL comes on, the slip indicator light also comes on regardless of the cause. Is this correct?

    its probably your gas cap. Did you Oil your filter? It could be that oil is on the MAF (or does that only affect us 1st gen guys?)

    I haven't gotten gas recently, but I am near the end of the tank. I will check it though to be sure.

    Also, the air filter comes preoiled so I would assume it was done correctly. I guess you can never really know for sure. I do not remember it looking or feeling too oily though

    I would check all of the connections as well, especially if you were under the hood putting in a CAI. My dad's '07 has the CE light come on when he went to pick it up from the dealer. After 2 days of diagnostics it turned out to be a loose VCT solenoid plug. He hasn't had a problem since. I would guess that if the traction control light is on as well you might have bumped something on the traction control unit since it is located near the CAI.

    That is correct. I believe it happens on all 2000+ Toyotas. If the check engine light comes on, the traction control is disabled. In some vehicles, like the Rav4, the 4wd will also be disabled.

    My 2010 (w/900 miles) is at the dealer right now for the CEL on.. apparently one of the emissions sensors (charcol filter?) went out- the CEL and the slip lights were both on and yes, that's standard when the CEL goes on.

    I'd take my truck straight to the dealer, I've only got 2500 on mine and I wouldn't even open the hood to check at this point. It's under warranty. They can spend their day checking it and fixing it.

    The dealer finally called me back. Apparently the code they got, I did not get the actual number(stupid me), said sensor out of range error, which the service guy was not expecting at all from our conversation earlier when I dropped it off.

    They cleaned the sensor anyway just to make sure it was not related to oil from the TRD oiled filter and then reset the system. Everything is fine now, I guess we will see how it goes.

    Sensor out of range does not make any sense to me and like I said, the service guy was perplexed as well.

    Just got home and while on the way home th CEL came back on.

    On the paperwork I got from the dealer the two codes listed are:
    P0101 and C1201

    Any ideas on what these might mean?

    Ugh...just spoke to the dealership and they want to try putting the stock airbox back on, clearing the CEL and running the truck to see if it returns.

    If it does not return they will contact Toyota and ask them to determine why the hell the Toyota approved factory part is causing these errors. If it returns with the stock box on, then they will start by replaceing the MAF sensor and going from there.

    Yeah, this is how I wanted to spend the first month with my new truck. :(

    I hate it when a new vehicle leaves a bad taste in your mouth.:mad:
