What is P0368 : Engine Error Code Causes Explained
Is your check engine light on showing the P0368 code? Don’t panic! This code refers to the Camshaft Position Sensor “B” Circuit Low – Bank 1. It means the ECM/PCM has detected a low voltage signal from the secondary camshaft position sensor on Bank 1.
📘 In this video, you’ll learn:
✅ What P0368 means — the camshaft sensor “B” on Bank 1 is not sending the correct voltage signal, which affects how the engine control module times fuel injection and ignition.
✅ Common causes include:
Faulty camshaft position sensor (Sensor B, Bank 1)
Damaged, loose, or corroded wiring/connectors in the sensor circuit
Timing chain or belt issues causing incorrect camshaft alignment
Faulty crankshaft position sensor (can cause false camshaft sensor errors)
Faulty ECM/PCM (rare)
✅ Vehicle symptoms may include:
Check engine light on
Hard starting or no-start condition
Engine misfires
Poor acceleration or hesitation
Rough idle
🎯 This code is especially common in engines with dual camshaft sensors (A and B). Sensor “B” usually refers to the exhaust camshaft on Bank 1, which is critical for variable valve timing systems.
👉 Quick Tip: Always check the wiring harness and timing components before replacing the camshaft sensor — many times, stretched timing chains or worn gears can trigger this code.
