Engine code.
Monday, July 10, 2006 12:06 PM
2000 pontiac sunfire 2dr. 2.2L 5spd.

The code from my reader: P0440

What that code is in the OBDII list....

Evaporative Emission (EVAP) System

Anyone have experience with this? From my emission test results about 4 weeks ago, the car runs EXTREMELY clean. Basically 0 readings for all categories.

Something to worry about? I'm used to OBDI

Usually just a loose or bad gas cap.

Thanks.

Thats what I figured. Odd that it passed the pressure test for the emission test though. Ohwell, I cleared the code.

Now for my other question, how do I check ABS codes?

With a Tech 2 diagnostic tool.... about $5000, or go see a GM dealer. Or any shop with a Snap-On diagnostic tool.

You need something that can see the individual sensors. Most simple scanners only read Powertrain codes.

My scan tool keeps saying no codes. Ohwell.

probably didnt tighten your gas cap properly after filling up one day. It probably went away after you filled up again and tightened it properly then cycled the car on and off a few times.
