    Good afternoon,
    I have a question regarding my '05. My "Check Engine" light has been coming on intermittently. I scanned for the code and I have received two; one indicating the ECM, and the other indicating high voltage at the O2 sensor. I brought the truck to my garage and my mechanic wasn't sure what it could be. He said that he would have to t.s. the electrical system point to point to try and isolate what's causing it to throw the code. I was wondering if anyone else has experienced this issue or a similar one. Any feedback would be greatly appreciated! Thank you!
