Question about Hyundai Motor 2004 Accent

1 Answer

What the heck does a P2096 DTC mean on a 2004 Hyundai Accent?

Got his code from AutoZone. Light came on after hitting a massive pot hole. Car seems to run fine. OBD-codes.com just freezes when I try to search.

Hi there:
DTC P2096 - Post Catalyst Fuel Trim System Too Lean (Bank 1)

Lean mixture code could be caused by a leakage in the rubber boot that is between the throttle body (similar to a carburetor) and the air cleaner housing. Following are all the tests to be done for a vehicle other than yours... HERE.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

My 2003 Hyundai Accent computer was read due to the Check Engine light coming on. The code that came up was a p2096-Post Catalyst Fuel System Too Lean. The guy said he never saw that code come up before...


Not a valid trouble code for 2003 Hyundai Accent but it is valid for 2004 Mazda RX-8. You don't replace ANYTHING until you find out why the mixture is too lean. This could be caused by at least 20 different things. If your shop doesn't know how to diagnose the root problem, find a shop that does. If you start throwing parts at this without diagnosing, you could easily drop $1,000 and still not fix the problem.

My check engine light has come on in a 2004 Hyundai Accent. There doesn't seem to be any problems, and the car only has 16,800 miles on it.


This is probably sensor or emissions related. You need to have the car scanned with diagnostic equipment in order to help pinpoint the cause of the problem. The vehicles computer will have retained a trouble code that can be picked up with a scanner.

Do not ignore it as this light is on for a reason. You can have a scan done at Autozone for free.

No tenago dinero y mi carro hyundai 2004 me esta dando problemas no coje la riversa y cambia de cantaso y le pusieren la maquina y me *** estos codigos p2o96,p0734,p0733,p1709,p2096


P0733 - Gear 3 Incorrect ratio
P0734 - Gear 4 Incorrect ratio
P1709 - Park or Neutral Position Switch out of Self-Test Range
Check out this TSB 03-40-016

Some 2000-2002 ACCENT vehicles may experience the following conditions: Diagnostic Trouble Code (DTC) P0722: No pulse generator-B signal Third-gear "Fail-Safe" condition
"Check Engine" light on

If the vehicle experiences the above symptoms: Inspect the pulse generator-B and replace if necessary.
Reprogram the TCM using the Hi-Scan Pro

VEHICLES AFFECTED: Model: 2000-2002 Accent vehicles with automatic transmissions
Affected vehicle production date range:
3 DR: Produced through October 11, 2002
4 DR: Produced through September 3, 2002

Affected vehicle identification number (VIN) range:
3 DR: Produced through KMHCF35C63U235415
4 DR: Produced through KMHCG45C03U412818

The problem is you will have to take it to the dealer to get the reprogram done.


P2096 - Fuel trim too lean. Usually means vacuum leak. Look for crushed, broken or melted off vacuum hoses near intake manifold. Or an obvious hissing noise at a normal idle. If so replace or repair clear codes your done. If not obvious take carb cleaner spray with nozzle attached car running & go over all vacuum hoses, intake manifold, EGR valve see if idle raises if so you found leak. Repair. Could also be bad oxygen sensor switching bad O2 sensor but rarely.


Hope this helps!

I have a 2006 hyundai accent it is idling high and it seems to me that the tranny is slipping when you first start the car and take off, the rmps hit about 4000 before it finally kicks, my check engine...


No one could tell me what was wrong with my 2006 hyundai . Why the check engine light kept being on. Autozone, Napa, Advance auto, their FREE diagnostic machine could not figure the problem.It kept reading p0012 and they didn't know what exactly that meant so... I had to give in and take it to the hyundai dealership and pay$99 for a real diagnostic test. That's when I was told it was my oil control valve and the problem got fixed, no more headache!
