P0367: Camshaft Position Sensor B Circuit Low Bank 1

Camshaft position sensor B is the exhaust camshaft sensor (bank 1 = side with cylinder 1), usually a Hall sensor on the exhaust cam phaser. The engine module holds the signal line at about 5 V and the sensor pulls it to ground with each tooth. P0367 means the line stays low without edges – typically a short to ground of the signal wire or a sensor shorted internally. A code-specific manufacturer description exists only from GM: on the Saab 9-4X 2.8 turbo V6 (LAU) the signal must stay low without pulses for more than 1 s, or 10 s cumulatively, after more than 10 crank revolutions and below 2,520 rpm, and the code follows after two trips; with the sensor disconnected the signal wire should show 4.8–5.2 V. GM's other engines of 2014–2019 and Ford report such faults under P0365. The consequence is as for P0365: exhaust cam timing in its base position, longer cranking.

Bank 1 is the side of the engine with cylinder 1. Inline engines only have this bank.

Symptoms

• Check engine light on
• Longer cranking before the engine starts
• Loss of power or rough idle (exhaust cam timing in its base position)

Most likely causes

• Signal wire chafed through to ground
• Sensor shorted internally
• Oil or water in the connector
• Engine module

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the connector and look for metal filings on the sensor
2. With the connector unplugged, check whether the signal wire is making contact with ground.
3. See whether there is an RPM signal while cranking
4. Measure the signal with an oscilloscope if you can
5. Check the engine timing before replacing expensive parts

Good to know

• Repair difficulty: easy
• It can trigger limp mode.
• It affects emissions.

What each character of P0367 means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• 3: Ignition and misfires
• 67: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0367?

Avoid driving: the engine can stall while moving. If the timing is off, continuing can cause serious damage.

What causes code P0367?

The most common causes are: signal wire chafed through to ground; sensor shorted internally; oil or water in the connector.
