Grand Cherokee P0700 Code Definition If you are scanning your vehicle right now, you should be looking for a second code that tells you what is actually wrong. Think about it like this.

• The Next Code(s) Say- "I'm the actual problem going on with the transmission. I'm what you're looking for."

Do you have a check engine light on and flashing? Have you run the OBD2 fault code test?

You need to have PCM / ECM - engine computer checked for DTC'S - diagnostic trouble codes an go from there ! there are hundreds of codes these newer vehicles can set ! I hope these people who changed the sensors an catalytic converter checked codes first ! You never ever just replace parts !!!!!!!! A DTC will lead in a diagnostic direction !

2008 jeep cherokee (hemi) engine light its on i brought to fix they change 4 sensor and the converter. After 5 days engine light comes on again, what else can be? im depress about it, after paying almost 2 grand to fix this issue.

The OBD is not that simple.

All it is saying is that it does not like the air/fuel mixture.
That can be from fouled spark plugs, an open gas cap or other intake leak, a bad O2 sensor, PVC foam on the air mass sensor, throttle position sensor, etc.
It is just like any carb engine when the mixture is bad.
You can't just read a number and know what to replace.
You have to have a feel for the symptoms.
And if there are no other symptoms, it could be the code is simply the only thing wrong.

Personally my best guess would the air mass sensor.
Look the inside of the oil cap. If there is foam there, then there is likely foam in the air mass sensor as well. PVC systems always throw foam into the sensor, and the only solution is to splice longer hoses into the system and into a condenser of some sort. This is worse in northern climates, in the winter. Most cars in cold conditions have this happening all the time. But as long as the light goes off eventually, don't worry about it.

without a dtc to help,the only thing you can do is check all the connections at the transmission,and unhook the battery for awhile or get check code cleared and see if it reapperars

Does it turn over? If not, try disconnecting the battery and reconnecting it. This has worked for my Jeep before.

Problem is a faulty Steering Angle Sensor (part of Steering Module) located in steering column ...replacement part $600.00.

The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.
