What this code means
P0369 may indicate an intermittent interruption in the camshaft position sensor B signal circuit, where the PCM can see abnormal pulse information from that sensor circuit.
What the vehicle may do
- The vehicle may act normally when the fault is not present.
- The symptom may be intermittent and can depend on operating conditions.
- Engine operation may be affected if the camshaft position signal drops out.
Possible fault areas
- CMP sensor B circuit connections may be loose or have terminal issues.
- PCM-side circuit connections may be involved.
- Engine ground or body ground connections may be involved.
- CMP pulse plate B may be loose or damaged.
- CMP sensor B may be a possible fault area after the earlier checks are normal.
Diagnostic path
Opening context
On this 2020 to 2025 Honda CR-V Hybrid, P0369 points to an intermittent interruption in the camshaft position sensor B circuit. In plain terms, the PCM is seeing abnormal pulse information from CMP sensor B. Because this can be intermittent, the vehicle may not act up all the time; it may idle or drive normally during one check and show a fault under the same conditions that originally set the code. The broad areas to keep in mind are the CMP sensor B circuit connections, PCM-side connections, engine and body grounds, the CMP pulse plate B, and the sensor itself. Start with the basic system checks, then follow a structured diagnostic approach instead of jumping straight to parts.
Duplicate the fault first
First, try to duplicate the fault. Enter maintenance mode, start the engine, and let it idle for 10 seconds or more. Then watch the HDS OBD STATUS for P0369. If the failure duplicates here, the confirmation procedure is complete and you can move into the circuit and component checks.
If it does not show up at idle
If the idle check does not bring the fault back, reproduce the captured operating conditions. Test-drive the vehicle for several minutes in the same range as the recorded on-board snapshot for engine speed and vehicle speed. After that, monitor the HDS OBD STATUS again for P0369. If the failure duplicates during this drive, the confirmation procedure is complete.
Check the CMP sensor B circuit connections
With the fault path confirmed, inspect the CMP sensor B circuit connectors. Check for a secure connection and loose terminals at CMP sensor B and at the PCM. If anything is abnormal there, treat it as a connection or terminal problem. If those connections and terminals look OK, continue in order.
Check the grounds
Next, check the engine ground and body ground connectors for secure connection and loose terminals. Again, if anything is abnormal, the problem is in the connection or terminal condition. If the ground-side connections and terminals are OK, keep going.
Inspect CMP pulse plate B
Now remove the cylinder head cover so CMP pulse plate B can be visually inspected. Look for looseness or damage. If the pulse plate is abnormal, the problem is with CMP pulse plate B. If there is no looseness or damage, continue to the final inspection logic.
Final diagnostic conclusion
If the connector checks, ground checks, and CMP pulse plate B inspection all indicate normal conditions, then the remaining fault area is CMP sensor B. At that point, the diagnostic result is that there is a problem with CMP sensor B.
Verification and takeaway
After correcting the condition found in the diagnostic path, verify the repair separately by rerunning the appropriate confirmation check and confirming P0369 does not return. The key takeaway is to prove the intermittent CMP signal fault first, then work through connections, grounds, pulse plate condition, and finally CMP sensor B without skipping the earlier checks.

Final check
P0369 is best handled by duplicating the fault, then checking the CMP sensor B circuit path, grounds, pulse plate condition, and final sensor fault logic in order.
