25% of P0364 cases are fixed by repairing wiring or connectors
The engine computer has an internal fault, misinterpreting the sensor signal or failing to process it correctly.
5% of P0364 cases are fixed by replacing the ECM/PCM
Check These First (Before Buying Parts)
- Visually inspect the Bank 1, Sensor B camshaft position sensor's electrical connector for any signs of corrosion, bent pins, or a loose connection.
- Check the wiring harness leading to the sensor for any visible damage, such as chafing, cuts, or signs of rodent damage.
How to Diagnose P0364
- 1Visually inspect the Bank 1, Sensor B camshaft position sensor and its electrical connector for any damage, corrosion, or loose connections.
- 2Check the wiring harness leading to the sensor for any signs of fraying, cuts, or shorts to power.
- 3Using a multimeter, test for proper voltage supply (typically 5V or 12V) and ground at the sensor connector.
- 4If possible, use an oscilloscope to check the waveform signal from the camshaft position sensor while cranking the engine.
- 5If all wiring and power checks are good, replace the camshaft position sensor.
P0364 on Popular Vehicles
Honda Accord
2003-2024Honda's VTEC systems are sensitive to cam sensor signals. P0364 on an Accord frequently indicates a faulty exhaust camshaft position sensor on Bank 1. Ensure you use a quality replacement part.
75% fixed by replacing the cam sensor
Nissan Altima
2002-2024Nissan vehicles, particularly those with VQ engines, are known for camshaft position sensor failures. P0364 on an Altima points to the exhaust cam sensor on the bank with cylinder #1. Check for oil contamination in the sensor connector.
70% fixed by replacing the cam sensor
Toyota Camry
2007-2024While less common than on some other makes, P0364 on a Toyota Camry can still occur due to a failing exhaust camshaft position sensor. Always inspect the wiring and connector thoroughly before replacing the sensor.

Frequently Asked Questions
What does P0364 mean?
P0364 indicates that the engine's computer has detected an electrical problem with the 'B' camshaft position sensor circuit on Bank 1, specifically a signal that is too high.
Can I drive with P0364?
Limit driving, fix within a few days. This code can cause stalling, hard starting, or a no-start condition, which are safety concerns. Avoid long trips or situations where engine reliability is critical.
Will P0364 clear itself?
No, P0364 will not clear itself. The engine computer stores this code until the underlying electrical fault is repaired and the system passes its self-test. You will need to clear the code with a scan tool after the repair.
How do I fix P0364 myself?
Start by inspecting the Bank 1, Sensor B camshaft position sensor and its wiring for damage. If the wiring is good, test the sensor's electrical connections. Most often, replacing the camshaft position sensor itself resolves the issue.
How much does it cost to fix P0364?
A DIY fix for P0364 typically costs $50-$200 for a new camshaft position sensor. If you take it to a shop, expect to pay $150-$500, which includes parts and labor for diagnosis and replacement.
P0364 keeps coming back - why?
If P0364 keeps returning, it often means the initial diagnosis missed something. Common reasons include a faulty wiring harness that was not fully repaired, a poor quality aftermarket sensor, or, in rare cases, an issue with the engine computer itself.
Will P0364 fail emissions/smog test?
Yes, P0364 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on automatically results in a failure in most jurisdictions, and a faulty camshaft position sensor can directly impact engine performance and emissions.
What's the difference between P0364 and P0365?
P0364 indicates a 'Circuit High' condition for the Bank 1, Sensor B camshaft position sensor, meaning the voltage signal is too high. P0365 indicates a 'Circuit Low' condition for the same sensor, meaning the voltage signal is too low or absent.
P0364 on Honda Accord
On Honda Accords, especially those with VTEC engines, P0364 often points to a failing exhaust camshaft position sensor on Bank 1. Wiring issues are less common but still possible. Always check the sensor and its connector first.
Questions to Ask Your Mechanic
Did you check the voltage supply and ground at the camshaft position sensor connector?
Good answer: Yes, I confirmed 5V (or 12V) power and a solid ground at the connector. The circuit itself is good.
What did the waveform look like from the camshaft position sensor?
Good answer: The waveform was erratic, showing spikes or flatlining, indicating an internal sensor fault. Or, 'The waveform was completely absent, pointing to a wiring issue.'

Cost of Waiting
Ignoring P0364 can lead to your engine stalling unexpectedly, difficulty starting, or a complete no-start condition, leaving you stranded. Continued driving with an incorrect cam signal can also cause reduced engine power and poor fuel economy.
While You're In There...
Clean engine oil is critical for proper camshaft timing and sensor operation. If the oil is dirty, it can affect VVT components and potentially the sensor's signal.
If the camshaft position sensor is located under the valve cover, replacing the gasket prevents oil leaks when accessing the sensor.
Tools You'll Need
- OBD-II scan tool
- Multimeter
- Basic hand tools (sockets, wrenches)
- Wire stripper/crimper (if wiring repair is needed)
P0364 is a common sensor-related code. Most repairs are straightforward, involving a sensor replacement, and your engine will run smoothly again afterward.

Your Next Steps
Step 1: Visually inspect the camshaft position sensor and its wiring for any obvious damage or loose connections. Clean any corrosion.
Step 2: Use a multimeter to test for proper voltage supply and ground at the sensor connector. If power or ground is missing, trace and repair the wiring.
Step 3: If wiring and power are good, replace the Bank 1, Sensor B camshaft position sensor. Clear the code and test drive the vehicle.
