OBD-II Code P0367 — What It Means & How to Fix It

What Does This Error Mean?

P0367 means the PCM is seeing a voltage signal from camshaft position sensor B on Bank 1 that is lower than it should be. Sensor B is the exhaust camshaft sensor in DOHC engines. Bank 1 is the side of the engine containing cylinder number 1. A low-voltage signal usually points to a bad sensor, a short to ground in the wiring, or a poor power supply to the sensor.

Affected Models

All 1996+ vehicles with DOHC engines and cam position sensors on the exhaust camshaft
Common in Toyota, Lexus, and Scion vehicles with VVT-i engines
Common in Honda and Acura DOHC i-VTEC engines
Common in Ford vehicles with dual overhead cam Ti-VCT engines
Common in Hyundai and Kia DOHC engines with CVVT variable valve timing

Common Causes

Failed camshaft position sensor B with an internally shorted signal wire
Short circuit to ground in the sensor signal wire between the sensor and PCM
Open circuit or high resistance in the sensor power supply wire
Corroded or damaged sensor connector causing a poor electrical connection
Failed PCM signal input circuit for camshaft position sensor B (rare)

How to Fix It

Use a multimeter to check the voltage at the camshaft position sensor B connector. With the ignition on and engine off, check the reference voltage pin. It should read approximately 5V on most vehicles. A reading well below 5V indicates a supply problem.

Disconnect the sensor before measuring to avoid a false reading from the sensor loading down the circuit. Check the reference voltage with the connector unplugged and the ignition on.
Inspect the sensor signal wire for damage. Look for pinched, abraded, or melted insulation along the entire length of the harness from the sensor to the PCM. A wire touching a ground point will drag the signal voltage down and set P0367.

Pay close attention to areas where the harness passes through grommets, near the exhaust manifold, or where it is secured with zip ties close to other wires. These are common chafe points.
Check the sensor ground circuit. A poor or missing ground can cause erratic or low voltage readings just as much as a bad signal wire. Verify continuity between the sensor ground pin and the vehicle chassis ground.

Resistance in the ground circuit should be close to zero ohms. Anything above about 0.3 ohms indicates a poor ground that needs to be cleaned or repaired.
Replace the camshaft position sensor B on Bank 1 if wiring checks out and voltage is abnormal at the sensor. Use a quality replacement that matches your engine's specifications. Reconnect firmly and clear all stored DTCs.

Before buying a sensor, confirm the part fits Bank 1 Sensor B on your exact engine. Intake and exhaust sensors sometimes look identical but have different internals or calibrations.
Clear all codes and perform a thorough test drive. Monitor live cam sensor data if your scanner supports it. If P0367 returns after a new sensor and clean wiring, have a professional measure the signal voltage directly at the PCM connector.

A recurring P0367 after sensor and wiring repair almost always means the PCM input channel is damaged — typically from a previous short circuit that sent excess voltage into the PCM.

When to Call a Professional

If you have checked the wiring and replaced the sensor and P0367 persists, the PCM input circuit may be damaged. A technician can measure exact voltages at the PCM harness connector to confirm whether the signal is low due to wiring or due to the PCM itself. PCM diagnosis and replacement is best left to a professional. Shop diagnosis typically runs $80-$150. PCM replacement is expensive — $300-$900 or more plus programming.

Frequently Asked Questions

What does low input mean on a camshaft position sensor code?

The camshaft position sensor sends a signal voltage to the PCM that varies as the cam rotates. Low input means the PCM is measuring a voltage on that signal wire that is lower than the minimum acceptable threshold. This can be caused by the sensor itself producing a weak signal, or by a short to ground in the wiring pulling the signal voltage down.

Can a P0367 code prevent the car from starting?

In some cases yes, particularly on engines where the PCM heavily relies on cam position data to calculate injection timing. Most of the time the vehicle will start and run but with noticeable drivability issues — rough idle, hesitation, poor response. If the car cranks but will not start and P0367 is present, the missing cam signal is a likely contributor.

Is P0367 the same as P0366 or P0365?

No, but they are related. P0365 means a general circuit fault on the Bank 1 cam B sensor. P0366 means the signal is present but out of performance range. P0367 specifically means the signal voltage is too low. All three point to the same sensor and circuit, but each narrows down the type of electrical problem involved.
