Hello All
I have a 2002 sport with the 4.0 Liter with the California emissions set up
I went to auto zone & got a loaner OBD2 scanner & i am pulling 6 codes
They are
P0161 02 sensor heater circuit malfunction bank 2 sensor 2
P0204 Injector Circuit, open cylinder 4
P0351 Coil A primary/secondary circuit malfunction
P0352 Coil B primary/secondary circuit malfunction
P0353 Coil C primary/secondary circuit malfunction
P0340 Camshaft sensor A bank 1 circuit malfunction
Now the question is how do i fix all this?
Thank you in advanced for any help |

What is involved with California emission setup?
One bad sensor can throw off others and cause the OBD system to think there are multiple problems.
I personally don't know exactly how to fix this particular problem, but I would start with the easiest and cheapest to replace first.
I don't like P0204 though. Are you the original owner of the vehicle? Does it have distributor? Or does it have coil packs on each plugs? And when was the last time this vehicle has been tuned up?

California emissions has 4 o2 sensors opposed to the standard 2
I am the second owner, i bought 2 years old in o4, it has the coil rail no distributor.
i try to keep up on tune ups every couple months weather it needs it or not |

I would start by unplugging and replugging the related electrical connections.
Then check grounds where things are grounded.
Was there any water damage? Did you ever wash your engine bay?
When did this start happening? What is the jeep doing other than lighting up CEL? |

It started back in January just b4 the original post.
It was bucking & stalling on my way home one day
I am in the proses of doing the rear main seal ((for a month now, time is limited)
I changed my plugs the other day, old ones looked bad so that may have been part of it.
also the vacuum line to my roll over sensor was disconnected. I am slowly finding small things that could have been part of the whole |

I am not sure if the O2 sensors on different locations are different on the 2002s, if they are the same swap their positions and see if the code follows it.

Or just move here to Hawaii and don't worry about the smog test!  |
