What this code means
P0369 may indicate an intermittent interruption in the camshaft position sensor B circuit, where the PCM can lose or see an abnormal CMP sensor B signal.
What the vehicle may do
- The vehicle may run normally when the interruption is not occurring.
- It can have intermittent drivability symptoms when the CMP sensor signal drops out.
- The warning light may come on when the PCM stores the fault.
Possible fault areas
- Possible CMP sensor B circuit connection or terminal concerns.
- Possible engine ground or body ground connection concerns.
- Possible CMP pulse plate B looseness or damage.
- Possible CMP sensor B concern if the earlier inspections are normal.
Diagnostic path
Opening context
On this 2018 to 2025 Honda Accord 2.0 Hybrid, P0369 points to an intermittent interruption in the camshaft position sensor B circuit. In plain terms, the PCM may be losing a clean signal from CMP sensor B at times. The vehicle may run normally when the fault is not active, or it can have intermittent drivability symptoms when the signal drops out. The broad fault areas can include the CMP sensor B circuit connections, loose terminals, engine or body ground connections, the CMP pulse plate B, or the sensor itself. Start with the basic system checks, and follow a structured diagnostic approach before getting into the pinpoint inspections.
Confirm the fault before testing parts
First, reproduce the operating conditions. Enter maintenance mode, start the engine, and let it idle for 10 seconds or more. Then watch the HDS OBD status in PGM-FI for P0369. If the failure duplicates here, the confirmation procedure is complete and you can move into the circuit and component checks.
Use the captured driving conditions if needed
If the idle check does not bring it back, use the second confirmation path. Test-drive the vehicle for several minutes in the same range as the recorded on-board snapshot parameters, focusing on engine speed and vehicle speed. Then monitor the HDS OBD status in PGM-FI again for P0369. Keep this confirmation work separate from the physical inspections; the goal here is only to prove whether the intermittent signal fault can be duplicated.
Inspect the CMP sensor B circuit connections
Once the fault is 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 those connections or terminals are not OK, treat that as the problem area before moving farther down the path.
Check the ground-side terminal connections
Next, check the connectors and terminals at the engine ground and body ground. You are looking for secure connections and no loose terminals. If this inspection is abnormal, the problem is in the connection or terminal condition at those grounds.
Inspect CMP pulse plate B
If the connector and ground inspections are OK, prepare for the CMP pulse plate B visual inspection by removing the cylinder head cover. Then inspect CMP pulse plate B for looseness or damage. If that visual inspection is abnormal, the problem is with CMP pulse plate B.
Final diagnostic call on the sensor
If the connector checks, ground terminal checks, and CMP pulse plate B inspection all indicate normal condition, the remaining call in this path is CMP sensor B. At that point, the diagnostic result is that there is a problem with CMP sensor B. If the path is unclear at any point, pause, recheck the earlier diagnostic path, and avoid guessing.
Takeaway and CTA
The key on P0369 is to confirm the intermittent signal fault first, then work through the connections, grounds, pulse plate, and only then make the final sensor call if everything else checks normal. For more diagnostic training, visit stepdiagnostics.com.
