Battery did not help. I did find this though and I’m going to order the sensor.
Just bought a new Plum Crazy Challenger Hellcat automatic. On the way home the Malfunction Indicator (MIL) Light came on along with the Electronic Throttle Control (ETC) light. Can not get them to turn off. Checking the diagnostics, it shows code: P00FB. Any idea what this code is? Thanks, Phil
