I got another code last week. Took it to Autozone and came up with P0442 Evap Emission System Leak (small). So the guy looks up a A/C evaporator core and says they don't carry it...is it me or was he a little I'm thinking possibly vapor canister in the fuel system..if the Rodeo is equipped with one. Can someone shed some information? I searched but no info came up on the code.

Also, unrelated, I've been having a noise coming from the right side of the engine bay intermittently when I apply the brake normally. Sounds like a fast clicking sound or fluttering sound for about a second. I've already had the ABS module replaced under warranty a few years ago. ABS light is not on....any ideas? I searched and found a post where a guy found a replacement on Ebay...I may do that if I can confirm that it's bad. TIA.

You got a real winner at AutoZone. I'm surprised he didn't try to sell you an O2 sensor. Next time you get a CEL, get the code read and go here. You can get troule code info at AllData.com if you have a DIY account.

An easy thing to try is to tighten your gas cap. A loose gas cap (could also be caused by the vapor canister or fuel tank pressure sensor) is the usual cause of the Evap Leak code.

yup, 99% of the time it is the gas cap.

Checked the gas cap and could see several cracks around the seal. I tightened it up and the CEL is gone. I'll pick up a new one this week.


Any thoughts on the ABS? Hoping someone had this same issue.
