Where is the bank 1 camshaft position sensor on a Subaru?
The bank 1 camshaft position sensor on a Subaru is typically located on the front of the engine, near the timing belt or timing chain cover. This sensor is responsible for monitoring the position of the camshaft in the engine's bank 1, which is the side of the engine with cylinder number 1.
Understanding the Camshaft Position Sensor
The camshaft position sensor is an important component in the engine management system of a Subaru vehicle. It provides the engine control unit (ECU) with information about the position of the camshaft, which is used to synchronize the opening and closing of the engine's valves with the movement of the pistons. This information is crucial for the proper timing of fuel injection and ignition events, ensuring the engine runs efficiently and effectively.
Locating the Bank 1 Camshaft Position Sensor
On a Subaru engine, the bank 1 camshaft position sensor is typically located on the front of the engine, near the timing belt or timing chain cover. The exact location may vary depending on the specific Subaru model and engine configuration, but it is generally easy to access and identify.
To locate the bank 1 camshaft position sensor on your Subaru, you can refer to the vehicle's service manual or consult a professional mechanic. They will be able to provide you with the exact location and guide you through the process of accessing and inspecting the sensor.
Importance of the Camshaft Position Sensor
The camshaft position sensor is a critical component in the proper operation of your Subaru's engine. If the sensor fails or provides inaccurate information to the ECU, it can lead to a range of issues, such as:
- Rough idling or stalling
- Reduced engine performance
- Increased fuel consumption
- Difficulty starting the engine
- Illumination of the check engine light
If you suspect an issue with the camshaft position sensor, it's important to have it diagnosed and repaired by a qualified Subaru technician as soon as possible to prevent further damage to your vehicle.
What side is Bank 1 on a Subaru?
Boxer/Flat Engines (Subaru): Typically, Bank 1 (passenger side) Sensor 1 is installed directly into the exhaust manifold collector or initial pipe section on the cylinder head located under the passenger side.
What is the code P0340 on a Subaru Bank 1?
The P0340 code indicates a camshaft position sensor circuit fault on Bank 1. Locate the sensor near the camshaft sprocket on the cylinder head. Symptoms include stalling, misfires, and traction control warnings.
Which side is the Bank 1 camshaft position sensor on?
Bank 1 refers to the side of the engine where the number one cylinder is located. To find the camshaft sensor for bank 1, first, identify the #1 cylinder, and then locate the sensor on the camshaft on that same side of the engine. For V-type engines, bank 1 is one side, and bank 2 is the other; for inline or four-cylinder engines, there is only one bank and the designation isn't relevant.

How to identify bank 1
- Locate cylinder #1: The first step is to find the #1 cylinder in your engine. You can usually find this by looking for the cylinder closest to the front of the engine, or the cylinder number plate.
- Determine the correct bank: The bank with cylinder #1 is always bank 1.
- Identify the camshaft sensor(s): Once you've identified the bank, find the camshaft position sensor(s) on that bank.
- Consider sensor types: If there are two sensors on bank 1, they are usually labeled as Sensor A (intake) and Sensor B (exhaust).

What to do if you have a code
- Use the code to pinpoint the issue: A diagnostic trouble code (DTC) like "P0340" will indicate which sensor needs to be replaced.
- Check wiring: After finding the sensor, inspect its wiring and connector for damage or corrosion.
- Test the sensor: You can test the sensor's output signal to see if it is faulty.
- Replace the sensor: Replace the sensor if it is faulty to restore proper engine timing and function.
