What this code means
P0369 may indicate an intermittent interruption in the camshaft position sensor B signal circuit.
What the vehicle may do
- The vehicle may run normally between faults.
- It can have intermittent drivability symptoms when the camshaft position signal is not clean.
- The fault may be easier to duplicate under captured operating conditions.
Possible fault areas
- Possible CMP sensor B circuit connection concerns
- Possible ground connection concerns
- Possible CMP pulse plate looseness or damage
- Possible CMP sensor B signal issue
Diagnostic path
Opening context
On this 2024 Honda Civic Sedan L4-1.5L Turbo (L15B7), P0369 points to an intermittent interruption in the camshaft position sensor B signal circuit. In plain terms, the PCM may be losing a clean pulse from that sensor at times. The vehicle may run normally between faults, or it can show intermittent drivability symptoms when the signal drops out. The broad areas to keep in mind are the sensor circuit connections, grounds, the CMP pulse plate, and the CMP sensor B itself. Start with the basic system checks and follow a structured diagnostic approach before narrowing it down.
How the code sets
The logic is straightforward: if the PCM sees abnormal pulsing signals from CMP sensor B, it determines there is an abnormality and stores P0369. So the diagnostic path is about first duplicating the fault, then checking the parts of the signal path that can make that pulse drop out or look wrong.
Confirmation check at idle
Begin by trying to duplicate the failure. Start the engine and let it idle for 10 seconds or more. While it is idling, monitor the HDS OBD STATUS under PGM-FI for P0369. If the failure duplicates here, the confirmation is complete and you can move into the circuit and component checks.
Confirmation check on the road
If the idle check does not duplicate it, test-drive the vehicle for several minutes in the same range as the captured engine speed and vehicle speed conditions. Use the PGM-FI data list for Engine Speed and Vehicle Speed so you are matching the conditions as closely as possible. During that drive, keep monitoring HDS OBD STATUS for P0369. If the failure duplicates, the confirmation is complete.
Check the CMP sensor B circuit connections
Next, inspect the CMP sensor B circuit connections. Check for a secure connection and loose terminals at CMP sensor B and at the PCM. Normal is that the connections and terminals are OK. If anything is loose, not seated, or otherwise abnormal, the problem is in the connections or terminals.
Check the grounds
After that, check the engine ground and body ground connection points the same way. You are looking for secure connections and loose terminals. If those checks are normal, the grounds pass this part of the path. If they are abnormal, the problem is in the connections or terminals.
Inspect CMP pulse plate B
With the electrical connection checks done, move to the mechanical side of the signal. Remove the cylinder head cover, then visually inspect CMP pulse plate B for looseness or damage. Normal is no looseness and no damage. If the pulse plate is loose or damaged, the problem is with CMP pulse plate B.
Final sensor conclusion
If the connector checks, ground checks, and CMP pulse plate B inspection all show normal conditions, the remaining item in this diagnostic path is CMP sensor B. At that point, the diagnosis points to a problem with CMP sensor B.
Closing takeaway
The key with P0369 is not to jump straight to the sensor. Duplicate the fault, match the captured operating conditions when needed, then work through the connections, grounds, pulse plate, and finally CMP sensor B. For more diagnostic training, visit stepdiagnostics.com.
Final check
P0369 often requires duplicating the intermittent fault first, then checking the signal path and related mechanical trigger area in order.
