20% of P0368 cases are fixed by repairing wiring or connectors
A faulty engine computer can misinterpret sensor signals or fail to process them correctly, though this is a rare cause.
5% of P0368 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Inspect the camshaft position sensor 'B' and its electrical connector for any visible damage, corrosion, or loose connections.
- Ensure the wiring harness leading to the sensor is not frayed, pinched, or shorted to ground.
How to Diagnose P0368
- 1Visually inspect the camshaft position sensor 'B' and its wiring harness for any obvious damage, fraying, or corrosion.
- 2Check the electrical connector to the sensor for looseness, bent pins, or corrosion; clean and re-seat if necessary.
- 3Using a multimeter, test the voltage at the camshaft position sensor connector to ensure proper power and ground signals.
- 4If possible, use an oscilloscope to monitor the sensor's signal output while cranking the engine to check for a proper waveform.
- 5If all wiring and connections are good, replace the camshaft position sensor 'B' (Bank 1).
P0368 on Popular Vehicles
Honda Accord
2003-2024P0368 on Honda Accords often points to a faulty camshaft position sensor, particularly on the exhaust side (Bank 1 'B' sensor). Wiring integrity should always be checked due to potential for rodent damage or corrosion.
80% fixed by replacing sensor or repairing wiring
Toyota Camry
2007-2024For Toyota Camry models, P0368 is commonly resolved by replacing the camshaft position sensor 'B'. These sensors can fail electronically, sending incorrect signals. Verify the connector is clean and secure before replacing the sensor.
70% fixed by replacing sensor
Ford F-150
2004-2024Ford F-150 trucks with P0368 often experience issues with the camshaft position sensor itself. Given the engine bay environment, inspect the wiring harness for chafing or damage from heat and vibration before condemning the sensor.

Frequently Asked Questions
What does P0368 mean?
P0368 indicates that the engine's computer has detected a high voltage signal from the Camshaft Position Sensor 'B' on Bank 1. This sensor monitors the camshaft's rotation, which is critical for engine timing.
Can I drive with P0368?
Limit driving, fix within a few days. While your car might still run, a faulty camshaft sensor can cause poor engine performance, stalling, and hard starting. Continued driving can lead to misfires, which can damage your catalytic converter over time.
Will P0368 clear itself?
No, P0368 will not clear itself. The underlying issue causing the high circuit signal needs to be diagnosed and repaired before the code will clear. Even if the Check Engine Light goes off temporarily, the problem is still present.
How do I fix P0368 myself?
Start by visually inspecting the camshaft position sensor and its wiring for damage. Check the electrical connector for corrosion or looseness. If these look good, you can test the sensor with a multimeter. If the sensor is faulty, replacing the camshaft position sensor 'B' is the most common fix.
How much does it cost to fix P0368?
DIY repair costs for P0368 typically range from $50 to $150 for a new camshaft position sensor. If you take it to a professional shop, expect to pay between $150 and $400, which includes parts and labor.
P0368 keeps coming back - why?
If P0368 keeps returning, it often means the initial repair didn't address the root cause. This could be due to a faulty wiring harness that wasn't properly diagnosed, a poor connection at the sensor, or, in rare cases, an issue with the engine's computer (ECM/PCM).
Will P0368 fail emissions/smog test?
Yes, P0368 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on is an automatic failure in most states, and a faulty camshaft position sensor directly impacts engine timing and emissions control.
What's the difference between P0368 and P0365?
P0365 indicates a general 'Camshaft Position Sensor 'B' Circuit' fault, meaning there's an issue with the circuit but not specifying the nature. P0368 is more specific, indicating a 'Camshaft Position Sensor 'B' Circuit High' condition, meaning the sensor is sending a voltage signal that is too high.
P0368 on Honda Accord?
On Honda Accords, P0368 is frequently caused by a failing camshaft position sensor, especially on models with VTEC systems. The sensor can degrade over time, leading to intermittent or constant high circuit signals. Always check the wiring and connector for corrosion or damage first.
Questions to Ask Your Mechanic
Did you check the wiring harness and connector for the camshaft position sensor 'B' for any shorts or corrosion?
Good answer: Yes, I performed a visual inspection and continuity test on the wiring, and checked the connector for any signs of damage or corrosion. Everything checked out fine.
What were the voltage readings from the camshaft position sensor 'B' circuit?
Good answer: I measured the voltage at the sensor connector and found a consistent high signal, indicating either a faulty sensor or a short in the circuit. After further testing, the sensor itself was determined to be the cause.

Beginner-friendly - The camshaft position sensor is often easy to access and replace with basic hand tools, and diagnosing with a multimeter is straightforward.
Cost of Waiting
Ignoring P0368 can lead to persistent engine performance issues like stalling and reduced power. Continued misfires, caused by incorrect timing, will send unburned fuel to your catalytic converter, potentially causing it to overheat and fail. A $100 sensor replacement now prevents a $1,200-$2,500 catalytic converter replacement later.
Tools You'll Need
- OBD-II scan tool
- Basic hand tools (sockets, wrenches)
- Multimeter
- Wire brush (for cleaning connectors)
P0368 is a common sensor code. Most repairs involve replacing a relatively inexpensive part and your engine will regain its normal performance afterward.

Your Next Steps
Step 1: Visually inspect the camshaft position sensor 'B' and its wiring for any obvious damage or loose connections. Clean any corrosion.
Step 2: If the visual inspection doesn't reveal the issue, use a multimeter to test the sensor's circuit for proper voltage and ground. If the sensor is accessible, test its resistance or signal output.
Step 3: If wiring and connections are confirmed good, replace the camshaft position sensor 'B' (Bank 1). You'll likely need one new camshaft position sensor.
