Hello all,
After doing a ton of Google searching I decided to join up this forum and ask for help.
My wife's 2008 2WD Rav4 2AZ-FE has had a history of what seems like slight hesitation from a slow rolling start (maybe this is normal).
Just yesterday we got the CEL/traction/slip light combo. Took it to Autozone and pulled code P0328 which is for the Knock sensor circuit malfunction.
Last night before bed I went ahead and re-tightened the gas cap. This morning all lights were gone and it ran fine for my trip to Autozone for the code pull. Then the warning lights came back on and limp mode started while sitting in the Chic-fil-a drive thru.
Thought maybe I got some bad gas so I bought some STP fuel system cleaner (i know its crap) and filled up with 93 octane from a DIFFERENT gas station.
Brought it home and disconnected the battery for 30 minutes then started it back up, no lights, ran great for a 20 minute drive. Brought it home cut it off, waited 5 minutes then drove it around the neighborhood and it faulted out again.
So from what I've read, it is unlikely that the knock sensor itself is actually bad. Possibly a loose wire or connector? I'm going to start tearing the intake apart tomorrow to access the sensor for inspection/testing. I just wanted to know if anyone has had or heard experiences with this issue and could maybe offer some insight.
Thank you in advance.
