Using GeekOBD APP, you can perform a scan to identify the P0368 code and any related codes. Monitor live data for the camshaft position sensor to see if its readings are within the expected range.

What vehicles are most commonly affected by P0368?

P0368 is frequently reported in vehicles like the 2015-2018 Honda Civic, Ford Focus, and Nissan Altima. It's beneficial to check for recalls or technical service bulletins (TSBs) related to your specific model.

How can I prevent P0368 from happening again?

Regular maintenance, including timely oil changes and inspections of the camshaft position sensor and wiring, can help prevent issues related to P0368.

What is P0368?

DTC P0368 is a diagnostic trouble code that indicates an issue with the camshaft position sensor circuit. This trouble code is relevant for vehicles equipped with variable valve timing (VVT) systems, such as the 2015-2018 Honda Civic and various models from Ford, Toyota, and Nissan. The camshaft position sensor plays a crucial role in engine timing, allowing the engine control module (ECM) to adjust valve timing for optimal performance and fuel efficiency. When the ECM detects a malfunction in the camshaft position sensor circuit, it triggers the P0368 code. Common symptoms include a check engine light, rough idling, and reduced engine performance. In severe cases, it may lead to stalling or difficulty starting the engine. If you ignore this code, it can result in further damage to the engine or emission components, leading to costly repairs. Therefore, addressing DTC P0368 promptly is essential for maintaining your vehicle's performance and longevity.

Symptoms

Common symptoms when P0368 is present:

  • The check engine light remains illuminated, indicating a fault detected by the ECM.
  • Engine hesitates during acceleration, leading to a sluggish response and potential stalling.
  • Fuel economy decreases significantly, typically by 10-15%, indicating inefficient engine performance.
  • Rough idling occurs, with the engine vibrating more than usual at a standstill.
  • Difficulties starting the engine can arise, particularly after the vehicle has been parked for an extended period.

Possible Causes

Most common causes of P0368 (ordered by frequency):

  1. The most common cause is a faulty camshaft position sensor, which occurs in approximately 60% of cases. This sensor can fail due to wear and tear over time or exposure to extreme temperatures.
  2. Another common cause is damaged wiring or connectors in the camshaft position sensor circuit. This issue can lead to poor electrical signals reaching the ECM, resulting in a malfunction.
  3. A third potential cause is oil sludge buildup in the engine, which can interfere with the sensor's operation. Regular oil changes can help prevent this issue.
  4. Less commonly, a failing ECM can lead to false readings from the camshaft position sensor, affecting the entire engine management system.
  5. In rare cases, physical damage to the camshaft or timing chain can affect the sensor's readings, leading to code P0368.
