Quick answer: The P0367 code indicates that your vehicle’s Powertrain Control Module detected a low voltage signal from the exhaust camshaft position sensor “B” on Bank 1. This affects the engine timing and fuel injection systems. While not immediately catastrophic, it requires prompt attention to prevent stalling, misfires, or engine damage.
Seeing a Check Engine Light popup with code P0367 can be stressful, but understanding what it means helps you address it calmly. This code points specifically to a reading issue within your exhaust camshaft sensor circuit. Below, we break down the symptoms, root causes, DIY checks, and realistic repair costs to help you resolve the issue efficiently.
What Does P0367 Mean?
The camshaft position sensor monitors the speed and rotational position of the camshaft, sending real-time data to your engine control module. The module relies on this signal to synchronize spark plug ignition and fuel injector pulse timing. Bank 1 refers to the side of the engine containing cylinder number one, and Sensor “B” typically indicates the exhaust camshaft sensor. When code P0367 sets, the computer detects that the sensor’s circuit voltage has dropped below expected operational parameters, preventing accurate engine timing management.
Symptoms
- Illuminated Check Engine Light on the dashboard
- Extended engine cranking time before starting
- Rough idling, engine shaking, or hesitation during acceleration
- Engine stalling unexpectedly while stopped or at low speeds
- Noticeable drop in overall fuel efficiency
- Decreased engine power under load
Possible Causes
Replacing the camshaft sensor immediately is a common mistake; often, simple electrical faults or engine oil issues trigger this code.
- Low engine oil level or dirty, sludge-filled engine oil
- Corroded, loose, or damaged wiring and harness connectors near Sensor B
- Faulty exhaust camshaft position sensor (Bank 1)
- Damaged, loose, or misaligned tone ring (reluctor wheel) on the camshaft
- Failing Variable Valve Timing (VVT) solenoid or mechanical actuator
- Rare internal failure of the Engine Control Module (PCM/ECM)
Check These Yourself Before Visiting a Mechanic
- Inspect your engine oil level and oil cleanliness on the dipstick, as low oil pressure directly compromises VVT components and timing sensors.
- Examine the wiring harness near Bank 1 exhaust camshaft sensor for burned, frayed, or rodent-damaged wires.
- Unplug the sensor connector to check for loose locking tabs, green oxidation corrosion, or engine oil seepage inside the plug pins.
How to Fix It
- Perform a thorough visual inspection of the engine oil level and sensor wiring harness. Top off or change dirty oil if needed.
- Connect an OBD-II scan tool to confirm P0367 and clear the trouble code to see if it returns right away.
- Test for steady power, ground, and signal voltage at the sensor plug using a digital multimeter.
- Check the resistance values of the camshaft position sensor against manufacturer specifications.
- Replace the Bank 1 exhaust camshaft position sensor if tests indicate internal sensor failure.
- Inspect VVT solenoids, mechanical timing components, or camshaft tone rings if wiring and sensor testing show no defects.
Estimated Repair Costs (2026)
| Job | Parts ($) | Labor ($) |
|---|---|---|
| Engine Oil & Filter Change | $30 – $60 | $40 – $70 |
| Wiring Repair / Connector Replacement | $20 – $50 | $100 – $200 |
| Camshaft Position Sensor Replacement | $40 – $110 | $90 – $180 |
| Variable Valve Timing (VVT) Solenoid | $70 – $160 | $110 – $220 |

Frequently Asked Questions
Can I drive with the P0367 code?
You can usually drive short distances to reach home or a repair shop, but extended driving is not advised. The engine may stall without warning in traffic, run harshly, or send raw fuel into the exhaust, potentially damaging your catalytic converter.
How do I clear the P0367 code?
You can clear the code using an OBD-II scanner connected to the diagnostic port under your dashboard. However, if the underlying circuit fault, bad sensor, or low oil condition is not fixed, the code and engine light will return shortly after starting the car.
What is the difference between Camshaft Sensor A and Sensor B?
In engine diagnostics, Sensor “A” generally identifies the intake camshaft position sensor, whereas Sensor “B” identifies the exhaust camshaft position sensor. Both monitor timing, but on different shafts within the cylinder head.
