P0365 on Kia by model: symptoms, diagnosis and fix
The CKP sensor on the Forte becomes heat-sensitive as it ages: the signal drops out once the engine bay is hot, so the engine stalls when coming to a stop or at idle, then refuses to restart until it cools for 10-20 minutes. Owners describe the car cranking normally with no spark/injection event and eventually setting P0335 (Crankshaft Position Sensor A Circuit). It is often misdiagnosed as a fuel pump or battery issue because the symptom is intermittent and disappears when the car is cold. Reported across the TD, Koup 2.4 Theta II, and YD/Forte5 cars.
Common Symptoms
- Engine stalls when slowing to a stop, especially when warmed up
- Cranks but will not start until it cools down
- Long crank time
- Tachometer drops erratically or reads zero while cranking
- Check engine light
How to Fix
Confirm before replacing: watch RPM in live data while the engine stalls or during a hot no-start crank - RPM dropping to zero while cranking points at the CKP. Check the sensor connector and harness for oil contamination and chafing, and verify the tone-ring/flexplate teeth are not damaged. Replace with a genuine Kia sensor rather than a cheap aftermarket unit, as owners report repeat failures with off-brand parts. The sensor is inexpensive; most of the cost is access labor. If P0365/camshaft codes appear alongside it, inspect the CVVT circuit and harness rather than blindly replacing both sensors.

Frequently asked questions
What does P0365 mean on a Kia?
P0365 stands for "Camshaft Position Sensor "B" Circuit (Bank 1)." This code means the engine computer detected a problem in the circuit for the 'B' camshaft position sensor on Bank 1 (typically the exhaust camshaft, or the second cam sensor on that bank). This sensor reports camshaft position so the PCM can correctly time fuel injection, ignition, and variable valve timing. A circuit fault here can cause hard starting, rough running, reduced power, or affect variable valve timing. While usually not an immediate breakdown risk, it should be addressed to avoid driveability and timing-related issues. On Kia it is documented across 1 model: Forte.
What are the most common causes of P0365?
The most common causes of P0365 are: Faulty camshaft position sensor (Bank 1, sensor B), Damaged wiring or connector at the sensor, Open or short in the sensor circuit, Corroded or loose connector pins, Reluctor/tone ring damage on the camshaft, Failing PCM (less common). The specific cause varies by vehicle.
How much does it cost to fix P0365 on a Kia?
Published repair estimates on Kia range from $120 to $400 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
