Hey Scotty, I got a 2007 Lexus RX350 2WD. Got a check engine light. Scanner tool shows P0560, along with p0300 on all 6 cylinders. I looked up the P0560 and it says it could be a voltage issue to the PCM. Is this a possible alternator problem? What are your thoughts? Car runs fine for the most part, with the A/C on the idle gets a little low and shaky but that's about it. 210,000 miles on it. I'm guessing all original coils, spark plugs look good. Alternator changed a couple years ago but it does click a bit here and there which I thought was just the pulley.
Just seems weird to me that it would code misfire on all 6 cylinders and the voltage at the same time?
Makes perfect sense. When system voltage drops, it affects ALL cylinders not just one or two.
Do a load test on the battery and alternator. When did you last clean the 15 year old fuel injectors?
I think I ran some fuel injector cleaner through there a few times. Just seems weird to me that it would code misfire on all 6 cylinders and the voltage at the same time?
Do the load test.
