EGR problem = causes the limp mode.

Basically this means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system. Symptoms You will likely not notice any drivability problems, although there may be symptoms such as a rough/hard idle when cold. Causes A code P0431 may mean that one or more of the following has happened: The catalytic converter is no longer functioning properly An oxygen sensor is not reading (functioning) properly There is an exhaust leak Possible Solutions Inspect for exhaust leaks. Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen O2 sensor while you're at it. One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into. Good Luck =)

Check the fuel pressure and compression and O2 sensors

Are they all out or just one? If there all out it's probably just a fuse, check the fuse panel..If it's just one the pull the cluster out and replace the bulb check for a loose wire

I'll have to do some research and get back with you, may have to send away for the information.

Hi June, I'm glad to help! June if it were me and if its summer time where you are I would simply bypass the heater core with a hose and fittings and worry about it before winter time. BUT, if it is in fact winter time where you are, then this is a big JOB, the entire dash will need to be removed and the A'C Housing will need to be removed. NOTE: I have never worked on one of these vehicles so I want you to understand that sometimes there is an easy access panel that can be removed and pull the heater core out which only takes a few minutes. NOTE: I'm not saying your vehicle has an access panel but just want you to be aware that some vehicles has it. Hope this helps and have an awesome day June! NOTE: I will do some research and if I find that your vehicle does have the access panel I will post it. BUT, if I do not post anything about it then that means you do not have the access panel. Have a good day!

You will need an ODB code reader, which will connect to the receptacle under the driver side of the dashboard, usually just below where the steering column is.
