Hi I just recently purchased this 04 chrysler sebring when I bout it I had a friend of mind that works on cars come with me to check it out. the lady I bough it off said the only thing wrong with it is that it needs a o2 sensor so I replace the o2 sensors as well as the plugs and wires an reset the battery and drove around all day.. the next day I went to start the car it came up with a code P2431 Secondary Air Injection System Air Flow Pressure Sensor Circuit Range/Performance Bank1 as well as another code U110C Network so after that I was confused I thought it was the o2 sensor but my test scanner gave me those 2 codes and the lady most of though it was the o2 sensor cause of it saying bank1 I cant seem to figure out what is generating this code any help would be appreciated

 

can anyone tell me the location of where the secondary air system sensor is located?

 

Does anyone knows if this model Sebring has a mass air flow system?

 

chrysler does not use a mass air flow system

 

Alright thanks can u tell me what takes the place of the mass air flow sensor?

 

a long drawn out mathematical algorithm in the computer.
Uses sensors such as cam crank TPS map air intake temp coolant temp outside air temp. battery temp and BARO. sooo thats what does it. FYI the chrysler computers are like APPLE to Windows is. Apple is a far better system but PC is more widely used as far as developers.

 

thanks for that info I already replaced the map sensor my guess is that its the air intake temp sensor gonna replace that next don't know what is giving off this P2431 code Secondary Air Injection System Flow Pressure Circuit Bank 1 I just can't figure it out

 

that would be a pump only used in northern part of the US it adds extra air into the exhaust to heat the cat up faster.

 

that maybe right I have just removed the connectors from the pump an it was full of water which caused corrosion an rust don't if there is a air pump relay or the location of where it may be I didn't see anything in the relay box or the owner manual on the location of the air pump relay or if there is even on for my model if this helps the vend number has a J in it

 

here are some pics of the connectors I still don't know if there is a air pump relay for my model if it may help my vend number has a j going by the link is a bit confusing for me http://www.moparpartsoverstock.com/s...modelYear=2004 also is there anyway to test the pump or the wiring don't wanna have to get a new one if not need
