Hyundai elantra 2007 once in a while the check engine light goes on and inspection failed due to codes P0700 and P0760. On occasion the car jerks while driving but rarely. What does this mean?

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?

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.

Did you use a aftermarket O2 sensor or a genuine Hyundai one? If it's an aftermarket one it may be bad or not as good as the OEM one. See here for more details and other potential causes: P0133

SOURCE: Check Engine Light on, codes P0605 and P0700

P0700 IS A CODE SAYING THAT THERE IS FAULT IN TRANS CONTROLLER..P0605 IS AN INTERNAL ERROR IN TRANS CONTROLLER..ACCORDING TO TEST,TRANS CONTROLLER MUST BE REPLACED
