i just replaced the timing belt, and asked the garage to look at the transmission for me because i thought i was experiencing some subtle shifting problems. they told me the transmission looked fine, but i needed a new filter and fluid. the engine light didnt turn on til a couple weeks later tho. does this sound like a new filter and fluid would fix this problem?

The sensor is located on the left hand rear side of the block (near the bell housing). It is held in place by a 10mm bolt. It's to the right of the exhaust manifold (LH - radiator side) on the V6. Once you purchase the new sensor you'll be able to identify it on the engine. The connector to this sensor is located in the illustration.
A word to the wise... replace the O2 snsr as well.

I am having the exact same problem with my 2001 Hyundai Elantra. I was told that the engine code that comes up when the sensor is on is called "Absolute Pressure In The Manifold". I was told by a "Hyundai Specialist" that when that code comes up it usually means that the seal on the manifold is Fuct. When my mechanic checked that out for me he had noticed that my manifold had 4 cracks in it(can varify cause he showed me). He replaced the manifold and gasket. The car ran fine for about 2-3 days and since then the problem has since come back and my check engine light will no longer go on/off it only stays on. Because of the check engine light always staying on I have noticed that on many occasions my car will hiccup many times in a row. The only way to stop the hiccup I have noticed is to take my foot right of the gas for approx. 2-3 sec then car will continue without hiccup(till it happends all over again). All in all I have been having this problem now for approx. 1 year and if there is somehow someway it could be repaired I would appretiate it.

Most of the time they mean:
p0441 = Evaporative Emission System Incorrect Purge Flow
p0422 = Evaporative Emission Control System Leak Detected (small leak)
