    My check engine light just came on my 05 Pre Runner (75K miles) this afternoon. I scanned it and it read P0606 (PCM Processor Fault). I just want to know what this means and if it's a major deal? I've read online that it's really not a huge deal, but I would like your opinions. Should I maybe try erasing the code and see if it comes back? Any input will be appreciated. Thanks...

    i work for toyota most times it is a shorted out a/f sensor. if you can check the reading of the volts while its running one of the sensors will stand out clearly replace that one
