2009 Camry 2.4 P0300, P0302, P0303 P
My wife 2009 Camry 2.4 runs great 99% of the time, but sometime it barely runs. I seems like that when it is shut off and restarted it runs fine. It sets the following codes. P0300, P0302, P0303P. I have installed new spark plugs. I switched coil pack #2 & #1 and #3 & #4. It still sets the same codes. I have a hard time thinking the #2 and #3 fuel injectors started acting up at the same time. It is hard to test when it runs good 99% of the time.
What else could be causing those codes? I appreciate any help. |
Does the check engine light flash during misfire?
Can you post the freeze frame data for the error codes? |
The check engine light was flashing when my wife was trying to get home. I have drove it on short drives only to get the light to turn on. The light has turned on for me but it has not flashed. My code reader is a basic one and only gives the codes. I have a better one(I hope) ordered and should be here Monday.
Thanks |
Check light flashing means a severe misfire that could damage the emissions converter.
Any issues of overheating or coolant loss? |
There is no coolant loss. It has not overheated. I drove it home last night (1 mile) and it misfired when I started it and set the same code. Then it ran fine.
|
Just to be clear, it sets P0300/0302/0303 correct?
No other codes? |
Yes just those codes. Could a PCV valve cause the misfire on just #2 and #3 cylinders? I put some Seafoam in the gas tank in case the fuel injectors are sticking.
Thanks for the reply |
Don't have an answer for you on the PCV.
Maybe when you get the scan tool and start looking at engine parameters it will tell us more. Question: when you examine the plugs from misfiring cylinder do they appear much different from the other plugs? Can you reproduce the misfire by wiggling/tapping the coil or injector connector/wiring? Have you disconnected/reconnected injector connector on the off chance doesn't have a good fit? |
The old spark plugs looked good, but the #3 plug had a small brown spot on the white electrode. Other than the small brown spot it looked good.
The connectors on the coils are good. I have not unplugged the injectors but I made sure they were connected. Last night It missed at starting and it ran fine after that. It did not set a code. Thanks |
This is the test results I got from my new scanner.
