The P0367: Camshaft Position Sensor ‘B’ Circuit Low (Bank 1) code indicates that the engine control module (ECM) is receiving a lower-than-expected signal from camshaft position sensor B on bank 1. This sensor monitors the position and speed of the camshaft to ensure proper engine timing and fuel injection. A low input signal could be caused by a faulty sensor, wiring issues, or other circuit problems.
P0367 – Quick Overview
| Meaning | P0367: Camshaft Position Sensor ‘B’ Circuit Low (Bank 1) |
| Is it serious? | Yes, this code can affect engine timing and lead to misfires, poor performance, or stalling, potentially causing engine damage if unresolved. |
| Possible causes | – Faulty camshaft position sensor B – Low input signal – Wiring issues |
| How to diagnose? | – Test sensor input – Inspect and repair wiring – Replace sensor if necessary |
P0367 Meaning
The P0367: Camshaft Position Sensor ‘B’ Circuit Low (Bank 1) code means that the ECM is receiving a signal from camshaft position sensor B on bank 1 that is below the expected range. This can disrupt engine timing and cause issues such as rough idling, misfires, or poor engine performance. The issue may be due to a faulty camshaft position sensor, wiring problems, or circuit issues.
Step-by-step diagnostic guide
Follow these steps to diagnose and resolve the P0367 code by addressing potential causes one by one.
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes that might provide more insights into the issue. | OBD-II Scanner |
| Inspect Camshaft Position Sensor B | Visually inspect the sensor for signs of damage, corrosion, or loose connections. Ensure the sensor is properly mounted and securely connected. | Flashlight, Safety Gloves |
| Test Camshaft Position Sensor Input Signal | Use a multimeter to test the input signal from camshaft position sensor B. Compare the readings to the manufacturer’s specifications to ensure the signal is within range. | Multimeter, Manufacturer’s Specifications |
| Inspect and Repair Wiring | Inspect the wiring and connectors leading to camshaft position sensor B for signs of damage, wear, or corrosion. Repair or replace any damaged wiring or connectors as needed. | Flashlight, Wiring Repair Kit |
| Replace the Sensor if Necessary | If the camshaft position sensor is faulty or providing a weak signal, replace it with a new sensor to restore proper engine performance. | Replacement Camshaft Position Sensor, Safety Gloves |
| Clear the Code and Test Drive | After completing repairs, clear the P0367 code using an OBD-II scanner. Test drive the vehicle to ensure the problem is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0367 code has not returned. If the code reappears, further diagnosis may be required. | OBD-II Scanner |
This diagnostic guide will help you accurately diagnose and resolve the P0367 code, ensuring that camshaft position sensor B on bank 1 provides proper input signals to maintain engine timing and performance.
