2016 RDX

Recently got P0333 intermittently. Engine feels and sounds fine but the code is concerning. Thought maybe it was bad gas or loose cap but have gone through at least a tank since. Comes on, clears itself after ~100 miles, then comes back on.

Wondering if it is a knock sensor gone bad.

Anyone have thoughts?

Same day I had what I think is a door lock actuator issue which has drained my battery and not allowing the alarm to come on. Don't think its related but suspicious timing.

 

I don't think this is related, you need to look at the sensor.

 

Hey there! I seem to be having a similar issue - mine may be a little different. I get a Check Emissions System Warning whenever the gas in the RDX is just below the half tank full mark.When we fill the tank up then the warning goes away almost immediately. It's been doing this for the past few weeks. I've even tried running the gas near Empty and adding a bottle of Techron High Mileage the last two times we've filled up. It's due for an oil change and I'm going to take it in this week but I was just curious what was found related to yours.

 

Here's a discussionon P0333
