What are the possible causes of a p0306 code?
P0306 Possible Causes. Faulty spark plug 6. Clogged or faulty fuel injector 6. Faulty ignition coil 6. Fuel injector 6 harness is open or shorted. Fuel injector 6 circuit poor electrical connection. Ignition coil 6 harness is open or shorted. Ignition coil 6 circuit poor electrical connection.
What does the p0306 code on a Honda Accord mean?
The P0306 code means that the cylinder 6 is misfiring or is randomly misfiring. Start by checking for intake leaks and if no leaks are found the next step is to replace the spark plugs on cylinder 6. If the problem persists more tests needs to be done to diagnose problem, see “Possible Causes”.
What to do if your p0306 cylinder 6 is reset?
Now, clear the codes and see if the P0306 is reset during a lengthy test drive. If the code is reset, use your vehicle information source to search technical service bulletins (TSB) which pertain to the symptoms and code (s) in question.
How much does it cost to repair a car p0306?
The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0306 code detected? Engine Cylinder 6 is Misfiring. P0306 Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light) Lack/loss of power Hard start Engine hesitation
Is the PCM able to set fuel injector troubles codes?
NOTE: On 1998 model year and newer, the PCM is able set specific fuel injector troubles codes (when they fail). Unfortunately, this rarely happens in real life. What you’ll usually see will be a misfire trouble code instead of a bad fuel injector code.

What should fuel injector resistance be in GM 3.8L?
The fuel injector resistance should be around 11.4 to 12.6 Ohms (although on your specific GM 3.8L car, this value might be a little different). Repeat test steps 1 through 4 on the remaining 5 fuel injectors.
Can a bad fuel injector cause a check engine light to come on?
A bad fuel injector can cause your 3.8L Buick (or Chevrolet, or Pontiac, or Oldsmobile) to idle rough, miss, and make the check engine light come on (if the vehicle is ODB II equipped, you could see misfire codes: P0300, P0301, P0302, P303, P0304, P0305, P0306). The good news is that testing for a bad fuel injector is super easy on the 3.8L GM V6.
How do you test the resistance of a fuel injector?
Probe the male spade terminals of the fuel injector with the multimeter test leads to get an Ohms measurement. It doesn’t matter what color test lead you use to test either of the two fuel injector male spade terminals, the polarity of the leads is not important when testing the resistance (Ohms) of the fuel injectors.
