P0367 — Camshaft Position Sensor "B" Circuit Low (Bank 1)

What exactly does P0367 mean?

P0367 means the Bank 1 camshaft position sensor B circuit is reading below the voltage level expected by the engine control module.

Can I drive with P0367 stored?

If the engine runs smoothly, you can drive cautiously to a repair shop, but stalling, poor power, or a no-start condition calls for roadside diagnosis or towing.

Does P0367 prove that the cam timing is wrong?

No. P0367 identifies a low sensor circuit and may result from a sensor, connector, ground, or wiring fault; it does not by itself prove worn camshaft timing.

What checks are needed to find the P0367 fault?

Use a scanner to confirm P0367 and review freeze-frame data, then test the sensor signal, reference voltage, ground, connector, and harness against the vehicle wiring diagram.

When your check engine light comes on and a shop scan reveals P0367, you're looking at a problem with the camshaft position sensor circuit on the exhaust side of bank 1. The PCM stores this code when it detects that the signal voltage from that sensor has dropped below the minimum acceptable threshold. In plain terms, the engine computer expected a clear electrical pulse from the sensor and received nothing useful, so it flagged the circuit as faulty.

The camshaft position sensor plays a critical role in modern engines equipped with variable valve timing. It monitors the rotation and position of the camshaft, feeding real-time data to the engine computer so it can precisely control valve timing, fuel injection, and ignition timing. Bank 1 simply refers to the engine bank that contains cylinder number one—on V-shaped engines this is the left or right side depending on the manufacturer, while on inline engines it's the only bank present. Because the PCM relies on this sensor to know where the camshaft is at any given moment, a low circuit condition throws off the entire timing strategy.

To set P0367, the PCM compares live sensor data against its expected voltage range over multiple drive cycles, not just a single event. If the reading stays out of bounds consistently, the code stores and the malfunction indicator lamp illuminates. The PCM also captures a freeze frame—essentially a snapshot of engine RPM, load, coolant temperature, and vehicle speed at the exact moment the fault first occurred. That snapshot is gold when you're trying to reproduce the failure condition during diagnosis.

Common Symptoms of P0367

• The engine may refuse to start entirely in severe cases
• Extended cranking time or difficulty starting the engine
• Noticeable increase in fuel consumption during normal driving
• The check engine light remains illuminated
• Reduced engine power and sluggish acceleration response
• In some cases, rough idle or stalling may accompany the above symptoms

What Causes P0367?

The most frequent culprit behind P0367 is a failed camshaft position sensor itself. Like any electrical component, these sensors degrade over time from heat and oil exposure. Beyond the sensor itself, several related issues can produce the same code:

• Dirty, low, or degraded engine oil disrupting VVT hydraulic operation
• A worn, stretched, or jumped timing chain/belt throwing off cam-to-crank relationship
• Damaged wiring harness, corroded connectors, or chafed insulation in the sensor circuit
• A stuck or clogged VVT oil control valve preventing proper valve timing adjustment
• Physical damage to the reluctor ring teeth that the sensor reads
• In rare cases, a failing PCM unable to process the sensor signal correctly

How to Diagnose P0367

Effective diagnosis separates a proper fix from throwing parts at the problem. Follow these steps in order:

1. Connect an OBD2 scanner, confirm P0367 is present, and record all freeze frame data. Note the specific driving conditions—RPM, load, temperature, speed—at the moment of failure.
2. Scan for any additional diagnostic trouble codes. Related codes often point toward the root cause rather than the symptom. Check for any factory TSBs (technical service bulletins) applicable to your specific make and model—manufacturers sometimes publish known issues and software updates.
3. Perform a thorough visual inspection of the wiring harness and connectors at the camshaft position sensor. Look for damaged insulation, corrosion, bent pins, or loose connections that could cause intermittent or permanent low voltage conditions.
4. Assess engine oil condition and level immediately. VVT systems depend on clean oil reaching the hydraulic passages. Dark, sludgy oil or a low oil level can cause VVT malfunction and trigger P0367 even when the sensor itself is fine.
5. With the scanner in live data mode, monitor commanded versus actual camshaft position while gently revving the engine. A healthy system should show the cam position responding smoothly to PCM commands.
6. Clear the code, complete a drive cycle that reproduces the freeze frame conditions, and verify whether P0367 returns. A code that does not return likely indicated an intermittent issue.

Repair Options for P0367

Approach repairs from simplest and cheapest to more involved work. The most common fixes for P0367 include:

• Camshaft position sensor replacement: $120–$350 (parts and labor)
• VVT oil control valve replacement: $200–$500 (parts and labor)
• Timing chain/belt repair or replacement: $800–$2,500 (parts and labor)

How Much Does It Cost to Fix P0367?

Actual repair costs depend entirely on what component triggered P0367 in your specific vehicle. Parts and labor at independent shops in the United States typically break down as follows:

Camshaft position sensor replacement runs $120–$350. The VVT oil control valve costs $200–$500 to replace. Timing chain or belt repairs—which may be necessary if jumped timing caused the sensor reading error—run $800–$2,500 depending on your engine.

Overall, addressing P0367 can cost anywhere from roughly $120 to $2,500 depending on which system failed. An accurate diagnosis before purchasing parts is essential. The sensor itself is usually the cheapest and most likely fix, while timing chain work represents the worst-case scenario. Never assume you need the most expensive repair without confirming it first.

Can You Drive with P0367?

Exercise caution. While the engine may still run, it will likely perform poorly and may enter a failsafe mode that limits power and engagement. If the underlying cause involves jumped timing or a severely malfunctioning VVT system, continued driving on an interference engine risks contact between valves and pistons—potentially causing catastrophic internal damage. Have the vehicle diagnosed before any extended trip.
