Car Question

The car had this engine malfunction code today:
P2097, which is Post Catalyst Fuel Trim System High Limit.

Soooooo.... what does that mean exactly? Google is not helping me in the matter....

Make/Model/engine?

White PT Cruiser. Looks like a hobbits car. She still needs a ladder to get in. [img]/LDPforum/ubbthreads/images/%%GRAEMLIN_URL%%/smile.gif[/img]

HAH You think you're so funny.... I'll have you know this is the red cruiser, and not the white one. SO there. And it has running boards. So I don't need a ladder.

hey wait - you stalking me dude?

The one time I saw you, you were in the white one. I was just hoping I'd hit on the right one. [img]/LDPforum/ubbthreads/images/%%GRAEMLIN_URL%%/smile.gif[/img]

Ahhh ok. That's ok then - a lot less creepy when you put it that way. That day I was in the white cruiser - that's basically the one I drive most.

The one with the gauge light on is the newer one (Cruiser #3 lol). Perfect car for hobbit sized people.

Oxygen sensor. There should be two on your exhaust system. One pre-cat and one post-cat.

What might be happening is that your pre-cat is malfunctioning, causing your post-cat to throw a code due to an enriched atmosphere.

Thanks - I couldn't find anything of that sort online. Shouldn't be too painful on the wallet to correct.

Those oxygen sensors can be pricey. A guy I used to work with had to replace 2 on a minivan a couple years ago and it was over $600.
