What P0368 means
Camshaft position sensor B is the exhaust camshaft sensor (bank 1 = side with cylinder 1), usually a Hall sensor on the exhaust cam phaser. P0368 means the signal line stays high without edges. If the signal wire is open, the roughly 5 V the engine module applies to it simply remains; if the sensor's 5 V supply or ground is missing, the sensor never switches and the signal also stays high – and a short to positive has the same effect. A code-specific manufacturer description exists only from GM: on the Saab 9-4X 2.8 turbo V6 (LAU) the signal must stay high without pulses for more than 1 s, or 10 s cumulatively, and the code follows after two trips; GM lists exactly these causes. 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, some loss of power.
P0368 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0368
- Check engine light on
- Longer cranking before the engine starts
- Loss of power or rough idle (exhaust cam timing in its base position)
Common causes of P0368
- Most likelyConnector off or corroded, signal wire open
- Possible5 V reference or ground of the sensor open
- PossibleSensor faulty (output does not switch)
- Less likelySignal wire shorted to positive
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0368 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3 | Area: ignition system or misfire. |
| 68 | The exact fault in that area. |
What to do next
- Note P0368 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0368
What does P0368 mean?
P0368 means "Camshaft Position Sensor B Circuit High 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0368?
Drive gently and only to a workshop. With P0368 the car can go into limp mode (reduced power) to protect itself.
Will P0368 fail an emissions test?
Yes, it can. P0368 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0368 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0368 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
