Detailed Description of Error P0368

OBDII error code P0368 is a generic trouble code that indicates a problem with the Camshaft Position (CMP) sensor B, bank 1, circuit high input. The CMP sensor is responsible for monitoring the rotation of the camshaft and providing the engine control module (ECM) with information about the camshaft''s position and speed. The ECM uses this information to determine when to inject fuel, ignite the spark plugs, and control the variable valve timing (VVT) system.

The CMP sensor B, bank 1, is located on the engine''s cylinder head and is specific to the bank 1 cylinders (cylinders 1-3 on most engines). The sensor is connected to the ECM via a wiring harness and provides a 5-volt signal that varies in frequency and amplitude based on the camshaft''s position and speed.

When the ECM detects a high input voltage from the CMP sensor B, bank 1, it sets the P0368 code and illuminates the check engine light. This code indicates that the ECM is receiving an abnormally high voltage signal from the sensor, which can cause the engine to run rough, misfire, or stall.

Possible Causes of Error P0368

  • Short circuit in the CMP sensor B, bank 1, wiring harness
  • Failed or faulty CMP sensor B, bank 1
  • Corrosion or water damage in the CMP sensor B, bank 1, connector
  • ECM malfunction or software issue
  • Wiring harness damage or chafing
  • Camshaft position sensor B, bank 1, circuit open or shorted to ground
  • Engine mechanical issues, such as a worn or damaged camshaft or valve train
  • Aftermarket accessories or modifications that interfere with the CMP sensor signal

Possible Fixes for Error P0368

  1. Check the CMP sensor B, bank 1, wiring harness for signs of damage, corrosion, or chafing, and repair or replace as needed
  2. Replace the CMP sensor B, bank 1, if it''s found to be faulty or failed
  3. Check the ECM for software updates or reflashing
  4. Inspect the camshaft and valve train for signs of wear or damage, and repair or replace as needed
  5. Check for aftermarket accessories or modifications that may be interfering with the CMP sensor signal and remove or modify as needed
  6. Use a scan tool to monitor the CMP sensor B, bank 1, signal and voltage to help diagnose the issue
  7. Consult a professional mechanic or the vehicle''s repair manual for further diagnosis and repair
