P0364 Code – What Does It Mean & How To Fix It

This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it.


P0364 is the Diagnostic Trouble Code “DTC” for a specific problem with the Camshaft Position Sensor “B” circuit, which might be intermittent. The OBDII system, used in modern vehicles to monitor and report problems related to different engine components, uses this code as part of Onboard Diagnostics II.


The P0364 code indicates that the Engine Control Module (ECM) has detected an intermittent or irregular signal from the Camshaft Position Sensor “B” circuit. This sensor is critical for the engine control module, which will monitor camshaft position and timing to ensure proper engine performance.


A P0364 code may be caused by several circumstances, such as:

  • Wiring or connection problems in the circuit for the Camshaft Position Sensor “B”; a broken Camshaft Position Sensor “B.”
  • Disrupted sensor signals on occasion.
  • A camshaft that is faulty or damaged.
  • Issues with the timing chain or belt.
  • Rarely, there are ECM problems.


The following list of symptoms is typical for a P0364 code:

  • Illumination of the dashboard’s Check Engine Light (CEL).
  • Reduced engine power or performance when sensors fail intermittently.
  • A poor fuel economy.
  • Irregular engine starting or harsh idling.
  • Sporadic stalling or trouble starting the engine.


To diagnose a P0364 code, a mechanic or technician will typically follow these steps:

  • Use an OBD-II scanner to retrieve the code and any related codes.
  • Inspect the Camshaft Position Sensor “B” and its wiring for visible damage.
  • Test the sensor’s voltage and resistance to determine if it’s functioning correctly.
  • Check the camshaft and timing components for proper alignment and wear.
  • Clear the code and perform a test drive to see if the issue recurs during intermittent sensor signal disruptions.

Common mistakes

Common mistakes when dealing with a P0364 code include:

  • Replacing the sensor without checking the wiring and connectors for intermittent issues.
  • Neglecting to inspect the camshaft and timing components for problems.
  • Assuming the code is solely caused by a faulty sensor without considering other potential causes.

How serious is this?

The P0364 code should be dealt with quickly, as it may cause a decrease in engine performance, low fuel economy, or damage to the engine if not addressed immediately. While the vehicle may still be able to drive successfully, it is recommended that they are inspected and fixed as soon as possible, mainly if there are periodic problems.

What repairs can fix the codeS?

repair manuals

A P0364 code repair might entail:

  • If the Camshaft Position Sensor “B” is determined to be broken, replace it.
  • Fixing or replacing broken connections or wires in the sensor circuit.
  • If the camshaft is found to be damaged, it should be realigned or replaced.
  • Addressing any timing chain or belt problems.
  • Occasionally, if the ECM is found to be the cause of the issue, it may need to be replaced.

Related codes

Related codes may include:

  • P0360 – Camshaft Position Sensor “B” Circuit Malfunction.
  • P0361 – Camshaft Position Sensor “B” Circuit Range/Performance.
  • P0362 – Camshaft Position Sensor “B” Circuit Low Input.
  • P0363 – Camshaft Position Sensor “B” Circuit High Input.


A P0364 DTC code is indicating an intermittent problem with the Camshaft Position Sensor “B” circuit, which may hurt engine performance and efficiency. To avoid further damage and guarantee the correct functioning of the vehicle, timely diagnosis and repair are necessary. Depending on the precise cause of the code, repair may include sensor replacement, circuit repairs, camshaft examination, and timing component adjustments.
