PO340 CODE FLASHED ONCE WHAT SHOULD I DO - 2003 Kia Sedona

Appears there was a recall on that sensor over 10 years ago. Many complaints that the dealers just flashed the cpu instead of replacing the part. Many complaints about Duralast replacement parts for this sensor. Replace the sensor should solve your problem if it has rough running or not.

Hi. It could be the cam adjuster or the Timing chain stretched.

Trouble Code: P0340

Camshaft Position (CMP) Sensor Circuit

Possible Causes:

The following conditions may cause this DTC to set:


Incorrect harness routing near secondary ignition componentsIgnition coil arcing to wiring harness or ignition control (IC) module--Inspect the ignition coils for cracks, carbon tracking, or other signs of damage.Camshaft reluctor wheel damageThe sensor coming in contact with the reluctor wheelForeign material passing between the sensor and the reluctor wheelExcessive camshaft end-play

Trouble Code: P0340

Camshaft Position (CMP) Sensor Circuit

Possible Causes:


Inspect the 16-way engine harness to fuel injector harness connector, the CMP sensor connector, and the ECM connector for corrosion.With a DTC set, the engine may crank for an extended period of time at start-up.

The code is for a problem with the cam sensor for bank one.
The sensor and circuit would need to be tested.

Camshaft positioning sensor needs to be replaced. im not sure if there is more than one on the vehicle but that can be quickly diagnosed at a repair shop.

any electrical noise in the system may trip the p0340. check plug wires for arcing. the most likely culprit is the alternator. unplug the alternator, and i bet the code can be cleared. had this happen to me once.

you can do 1of two things 1pull the cam sensor out and clean it up and reinstall it to see if that works or you can replace it with a New one, this is what the code po340 means that you have a problem with the cam sensor

Hi

Ah! you posted P0304!

I assume the two bad wires were the problem?

Very best regards
