P0369
Camshaft Position Sensor B Circuit Intermittent (Bank 1)
If your code reader dashboard displays the generic DTC error code P0369, your vehicle is currently experiencing an active failure related to "Camshaft Position Sensor B Circuit Intermittent (Bank 1)". Proper system troubleshooting is required to safely clear this warning.
Driver's Summary
The diagnostic trouble code P0369 indicates an active fault in the camshaft position sensor b circuit intermittent (bank 1) circuit or component. On the road, this usually shows up as intermittent engine shudder, stalling on bumpy roads. This is a serious fault — avoid extended driving and have your vehicle inspected by a mechanic as soon as possible to prevent further damage.
Symptoms
Intermittent engine shudder, stalling on bumpy roads
Common Causes
- Loose electrical connector
- Frayed wiring shorting to ground
- Internally failing sensor
- Excessive camshaft end play
How to Fix
- 1 Secure connector tightly
- 2 Repair wiring harness
- 3 Replace camshaft position sensor
- 4 Measure and repair camshaft end play
Technical Explanation
The PCM triggers P0369 after its internal monitoring routine detects that a specific circuit or sensor has exceeded its acceptable operating range. The PCM monitors crankshaft rotational velocity via the CKP sensor at a resolution of individual tooth gaps on the reluctor ring. A combustion event in each cylinder produces a measurable acceleration spike; its absence or weakness is flagged as a misfire event within a 200-revolution or 1000-revolution test window. After two failed drive cycles, the code transitions from a pending to a confirmed DTC, and the PCM activates the MIL. Clearing the code without repairing the fault will result in re-illumination within one to two complete drive cycles.
Is It Safe to Drive?
An active P0369 code under high-severity conditions means the affected system is operating outside safe parameters. Continued driving — especially under load or at highway speeds — significantly increases the risk of secondary damage to components like frayed wiring shorting to ground.
Mechanic's Pro Tip
With P0369, always change the engine oil with the correct factory viscosity as the absolute first step before any electrical testing — dirty or wrong-viscosity oil prevents VVT actuators from responding properly regardless of solenoid condition. After the oil change, warm the engine fully and monitor camshaft advance angle live on a scan tool; if it still won't advance to the commanded target, then test the VVT solenoid. Cleaning the solenoid's internal filter screen (often packed with sludge) resolves a large percentage of these codes without replacing the solenoid.
