Hyundai Elantra engine issues with code P0269, suspected crankshaft sensor failure when hot on Hyundai Elantra

Some Hyundai Elantra owners report experiencing engine issues related to diagnostic trouble code P0269, which indicates a Cylinder 3 Contribution/Balance Fault. These owners have noted symptoms such as reduced engine performance, power loss, rough idling, and engine misfires. Specific reports from 2015 Elantra 1.8 liter owners include hard starting, random stalling at stop lights, and intermittent tachometer problems alongside code P0335. The P0269 code can stem from various causes, including a faulty or clogged fuel injector on cylinder 3, low compression in that cylinder, or instability in engine performance due to injector issues. During the diagnostic process, these owners emphasize the importance of inspecting the crankshaft sensor, fuel injectors, and cylinder 3 components, recommending the use of OEM sensors for replacements. Overall, addressing suspected crankshaft sensor failures and other potential causes is crucial for proper diagnosis and resolution of these engine problems.
