Camshaft Position Sensor B Circuit Low Input (Bank 2)

Definition source: General OBD-II reference catalog
Definition verification: Not independently verified for display.
Time: Varies by diagnosis and vehicle | Diagnostic difficulty: Medium
Medium Severity

The camshaft position sensor reports camshaft position so the engine computer can coordinate engine timing and synchronization. This code means the computer detected a low electrical input in the Sensor B circuit for Bank 2. It identifies a circuit condition, not proof that the sensor itself has failed. Exact sensor identification and diagnostic procedures depend on the vehicle’s model, year, and engine.

⚠️ Before You Begin (Safety First)

If the engine stalls, runs very poorly, or becomes difficult to control, pull over safely and arrange diagnosis rather than continuing to drive. If the check-engine light is on but the vehicle runs normally, have the fault checked soon; monitor for worsening symptoms.

Common Symptoms

  • The check-engine light may be on because the engine computer has detected a low input in the Sensor B Bank 2 circuit.
  • The engine may be harder to start if the computer cannot reliably use the camshaft position signal for synchronization.
  • Rough running, reduced performance, or stalling may occur if engine timing or synchronization is affected.
  • There may be no noticeable symptoms, especially if the detected circuit condition does not significantly affect engine operation.

Common Causes

  • A damaged, corroded, loose, or poorly connected Sensor B Bank 2 connector can disrupt the circuit signal.
  • Wiring damage or a short to ground may pull the circuit input low.
  • A failed camshaft position sensor may produce an abnormally low signal.
  • A problem with circuit power, ground, or another connected circuit component may cause the low input.
  • A fault in the engine computer or its circuit may be possible, but should be considered only after other causes are checked.

Diagnostic Steps

  1. Record the code and any other stored codes before clearing anything; related codes and symptoms can help guide diagnosis.
  2. With the engine off and cool, visually inspect accessible wiring and the Sensor B Bank 2 connector for looseness, corrosion, chafing, or damage. Do not pull on wires or disconnect components while the engine is running.
  3. Check whether the engine has starting, running, or stalling symptoms, and note when they occur. This helps assess whether the signal problem is affecting operation.
  4. Use vehicle-specific service information to identify the correct sensor and circuit before attempting electrical checks; Sensor B and Bank 2 identification varies by engine.
  5. If the connector or wiring is not visibly damaged or the code returns, have the circuit tested with suitable equipment. Avoid guessing at parts or probing wires in a way that could damage insulation or connectors.

When to Call a Professional

Confirm the code and related codes with a scan tool, and review available freeze-frame data. Inspect the Sensor B Bank 2 connector and wiring, then test the circuit’s power, ground, and signal using the vehicle-specific wiring diagram and service information. Signal analysis may help distinguish a sensor or wiring fault from an issue elsewhere in the circuit. Verify any repair by checking that the fault does not return.

Commonly Asked Questions

Does P0367 prove that the camshaft position sensor needs replacement?

No. It reports a low input in the Sensor B Bank 2 circuit. Wiring, connector, power, ground, or other circuit problems can produce the same condition, so diagnosis should come before replacing parts.

What does “Sensor B, Bank 2” mean?

It identifies a particular camshaft-position circuit on the engine’s Bank 2 side. The exact sensor location and which camshaft it monitors depend on the engine; use vehicle-specific service information to identify it.

Can I drive with this code?

Some vehicles may continue to run with few noticeable symptoms, but starting or running problems and stalling are possible. If the engine stalls or runs very poorly, stop driving when safe and arrange assistance.

How is a low-input circuit fault distinguished from a bad sensor?

A technician checks the connector and wiring and tests the circuit’s power, ground, and signal using the vehicle-specific diagram. Appropriate signal testing can help determine whether the sensor or another part of the circuit is responsible.
