Hey there, new member here looking for help. I have an '09 base model that's been giving me trouble in recent months.
Started out six months ago, it jumped whenever I'd accelerate. The code came back 340, camshaft position sensor. Got that changed, it was fine for a couple months, then on the freeway one day, decided to start jumping again. Pulled it over to check codes (340 again), and it wouldn't start without a battery disconnect and some cajoling. Cleaned the sensor, still wouldn't start, let it sit for a couple weeks and drove a different car. Started right up again and drove around town for a few days without problems, so I took it on a road trip, only to have the same lurching once again. Limped home and it wouldn't let me hit 60 without serious jumps...it was a long ride! That was last night, and today it won't start again. Google suggests this is a spark plug issue, those have been replaced within the year. Not sure if this is related, but I've also had an ongoing problem with the idle during humid weather. After sitting for a minute or two, it kicks into high idle and the AC blows hot. I live in humid Houston, this is not an issue when I drive to Colorado, even in the summer, so it's just in humid weather. Once, it was totally fine until we hit Dallas, and sure enough, it was humid in Dallas. Been trying to figure that one out for a long time. Anyway, I know this is a long post, to review: -code 340 (CPS) -camshaft position sensor replaced less than 6 months ago -lurches on acceleration and at 60 mph -occasionally will not start -new spark plugs within the year -idles hot in humid weather |

Was the sensor an oe or aftermarket, some aftermarket sensors act up and was the magnet changed. Other than that that's all I got. Sure someone may have some ideas.

I have to go with what robh said. AC is not my strong suit.

Clean the connectors for the camshaft sensor on sensor itself, and the harness. You may have a bad crank sensor since others have suggested that with a p0340 on these forums. As for overheating, does fan run when ac is on? Should be on low with AC on. Also, it should be at full speed when car reaches about 205 degrees |
