Experiencing Obd2 Code P0017 after recently having timing components replaced can be frustrating. This code, specifically P0017 Crankshaft Position – Camshaft Position Correlation (Bank 1 Sensor B), indicates a mismatch between the crankshaft and camshaft positions in your engine. While your 2013 Kia Rio had its timing chain, tensioners, and actuators replaced, the recurrence of code P0017 suggests the underlying issue might not be fully resolved, or a new problem has emerged.
The P0017 code essentially means that your engine’s computer (PCM or ECM) is detecting that the crankshaft and camshaft are not properly synchronized. This synchronization is crucial for the correct timing of valve opening and closing in relation to piston movement. When these components are out of sync, even slightly, it can lead to noticeable engine performance issues.

Several factors can contribute to a P0017 code reappearing after timing work. While the timing components themselves were addressed, potential causes can include:
- Incorrect Timing Components Installation: Even a slight error during the installation of the new timing chain, tensioners, or actuators can lead to timing misalignment and trigger P0017.
- Faulty Camshaft or Crankshaft Position Sensors: The sensors themselves could be malfunctioning or providing inaccurate readings to the engine computer, even if they were not replaced during the initial repair.
- Wiring or Connector Issues: Problems with the wiring harness or connectors leading to the camshaft or crankshaft position sensors can interrupt the signal and cause a false P0017 reading.
- Oil Pressure Problems: Proper oil pressure is vital for the correct functioning of variable valve timing (VVT) systems, which rely on the camshaft actuators. Low oil pressure can affect actuator performance and lead to timing discrepancies.
- Underlying Mechanical Issues: In rare cases, other mechanical problems within the engine could indirectly affect timing and trigger P0017.
The symptoms you described, such as rough idling, weak acceleration, and a flashing check engine light, are consistent with a P0017 code and timing-related issues. The flashing check engine light often indicates a more severe misfire or engine problem that could potentially damage the catalytic converter if ignored.
To properly diagnose the recurrence of P0017, and address the rough idling, a systematic approach is needed. Here are some steps to consider:
- Retrieve Diagnostic Trouble Codes: Even if the check engine light is currently off, a professional scan tool can retrieve any stored or pending codes, which might offer more insight than just P0017.
- Inspect Camshaft and Crankshaft Position Sensors: Check the sensors and their wiring for any signs of damage, corrosion, or loose connections. Testing the sensors’ resistance and signal output can also be beneficial.
- Verify Timing Components Installation: It might be necessary to re-examine the timing components to ensure they were installed correctly and are functioning as intended.
- Check Oil Pressure: Assess the engine’s oil pressure to rule out oil pressure issues affecting the VVT system.
Regarding the horn and door lock issues, while they might seem unrelated, electrical problems can sometimes manifest in various seemingly disparate systems in modern vehicles. It’s possible there’s a broader electrical fault affecting multiple components. A thorough electrical system diagnosis might be necessary to address these issues alongside the engine code P0017.
In conclusion, while timing component replacement is a common fix for P0017, its reappearance indicates a need for further investigation. Given the complexity and potential for engine damage, seeking professional diagnosis from a qualified mechanic is highly recommended. They can accurately pinpoint the root cause of the recurring P0017 code and ensure proper repairs are carried out, addressing both the engine timing and any related electrical concerns in your Kia Rio.
