I stalled my manual 2008 base model fit trying to start up a really steep hill. The car stalled and a strong smell of gas occurred. The check engine light went on and my car wouldn't start for about 3 minutes. Afterward the engine light stay on for a bit before turning off on its own.

My curiosity got the best off me so i bought a BAFX OBD2 reader. Using the torque app i get the code P0339. Not sure if the code happened because of the the stall or something already wrong with it.

Right now it idle pretty rough in the morning, Seem to stutter on first and second gear. Sometime it feel like the engine is trying to catch up when i press down on the gas, other time it drive just fine.

I'm changing the coil packs and spark plugs tomorrow. According to google the PCV valve is clog or something and i need to clean it out. Is that true ?

What else should i be looking at ?

 

My US market manual says its the CKP sensor Circuit intermittent interruption. CKP is the crankshaft position sensor. The sensor is located near the bottom rear of the engine on the camshaft chain case. Because it's intermittent I'd start by checking connections any more investigation requires the Honda diagnostic box to troubleshoot the health of the sensor. Replacing the sensor requires a learn procedure from the dealer's box or you can do the learn procedure yourself by following this procedure if you choose to take a chance and replace the sensor:

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator fan comes on.
2. Test drive the car in a level road. Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm down to 1,000 rpm with the A/T in 2 position, or M/T in 1st gear.
3. Repeat step 2 several times.
4. turn the ignition switch off.
5. Turn the ignition switch ON (III), and wait for 30 seconds. The CKP pattern learn procedure is complete.

From my limited experience with honda coil packs they seem to be pretty solid so I'd hold off on replacing them right away. But changing the plugs and replacing the PCV valve and tubing should be beneficial. Just be careful removing the plugs if they've never been out before. I'd make sure the engine is cold before changing the plugs.


I'd try the plugs and pcv valve first. Any other experiences with Honda coil packs out there?

 

I already bought spark plugs along with the Ignition packs. Should I just change the spark plugs and leave the ignition packs alone until it is broken ?


Do you have some sort of diagram showing where the CKP sensor is at ? can it be easily access and clean ?

 

I cleared the code and the error code went away. Now I'm wondering if changing spark plugs and coil packs is even worth it at 90000 miles.

 

If you can't return the coil packs then I say go ahead and use them along with the spark plugs. At least you'll know they are all brand new. The upside is you will have ready spare packs if you need one in a pinch. Also at the very least I'd pull and check the plugs even if you choose not to replace them (don't try to gap them).

The only thing I could find to show the CKP sensor is this:
Honda Automotive Parts

The CKP sensor looks like a magnetic pick-up type sensor that so I'm not sure if it will benefit from cleaning.

Good to hear the code is staying away, does it drive better now too?
