Sorento are known to have electrical promblem and short sensor, and parts. It could be your main fuse box that may need to be replaced. I had a 07 sorento, and i'm glad I got rid of it. Changed my mass airflow sensor 3 times within 7 months that also caused a check engine light to come on. Took it to dealer, and they had to replace the main fuse box. After that, i've already spend to much money, and who knows, with many others complaining about other eletrical promblems. It was best indeed to get rid of it. So my opinion is to take it to a dealship and have them take a look at it and tell them you replaced it already, and see what they tell you. Fix it and get rid of it.

2004 Sorento began with code P0305, cyl #5 misfire. Inspected and replaced plugs, wires, and coil pack on cyl #2. Repair shop told me cyl #5 injector bad so they replaced. Still has misfire.I suggeste


If you had code P0305, I don't know why they would have done anything to the #2 cylinder but if they have already replaced the plugs, wires and injector; here are a few more items to check:
1) Check connections from ECM. Look for any corrosions or bent/broken pins.
2) Check the fuel line pressure
3) Check the engine compression
4) And if the above are good, then you will probably have a defective ECM

2005 jeep liberty engine misfire cylinder 5


A code P0305 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer


If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

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, and have a nice day.

Check engine light is on with a code p01399 and p0301 - p0305


P1399 - Acura Random/Multiple Cylinder Misfire Detected.

P0301 and P0305 is refer at cyl #1 and #5 misfiring.

On most Honda's when you get a misfire happening across the whole engine like that there are a few likely issues. the ignition coil if it's a single coil style or the connector at the distributor. They also have some issues with EGR's and plugged ports which can mess with the fuel trim numbers. It's important to check the fuel pressure and if possible a timing offset spec from the scanner whenever you're dealing with misfires on any vehicles Honda or not and determine correct pressure and flow whenever possible.

A code P0301 and P0305 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
