Error codes that affect the drivability of the vehicle or the performance of the engine are quite serious. Ignoring these codes might lead to further engine malfunction and damage. That’s why, if the check engine light illuminates, you need to identify and address the issue it refers to immediately.
The P0345 code points toward a problem in the camshaft position sensor. What triggers this error code and what are its symptoms? What can trigger this code and how can you fix it? Read on to find out the answers to these questions and more.
Diagnostic trouble code (DTC) P0345 stands for “Camshaft Position Sensor “A” Circuit (Bank 2).” This code refers to an issue in the camshaft position sensor (CMP) circuit of the engine’s bank 2, which is the bank not containing cylinder #1.
The P0345 is triggered when the powertrain control module (PCM) detects an inconsistent signal or lack of signal from the CMP sensor.
The CMP sensor measures the exact rotational position and speed and position of the camshaft. The data that the CMP gathers is important because it’s used by the ECM to control the ignition spark and the fuel injector timing.
If you’re a DIYer planning to fix P0435 yourself, you can read about the camshaft position sensor and how it can trigger OBD codes.

Like all OBD-II codes, there are several possible reasons why a P0345 code is set. Proper diagnosis and repair can only start once the root cause has been found. Below is a list of some of the possible causes of P0345:
Below are some common indications that you might be dealing with the engine code P0345.
Note that a failed cam position sensor on Bank 2 of an engine with 2 banks will always store this code (or a P0340), but there may be no other noticeable symptoms.
Some cam sensors are adjustable, (like those in distributors or cam synchronizers that go where the distributor used to go on earlier engines). There are special tools and procedures for cam sensor adjustment, so don’t try to guess at adjusting the cam sensor. Cam sensors that simply bolt into the valve cover or cam housing aren’t adjustable and are basically plug-and-play replacements.
Diagnosing OBD-II codes like the P0345 code can be challenging because you’ll have to narrow down the exact cause from the list of all possible causes. If you’re unsure of how to go about the process of diagnosis or you’re not that confident with your DIY automotive repair skills, go to your trusted mechanic to have the issue checked.

Replacing the CPS is not a guaranteed fix for the P0345 code. The DTC indicates an issue in any part of the circuit, which includes the CPS, the wiring, or even the PCM. The only way to resolve it is to address what caused it.
Find the right solution with materials like repair manuals and other resources. The repair process may also vary depending on your vehicle’s make and model, so be sure to research confirmed fixes that are specific to your car. When in doubt, don’t hesitate to contact your mechanic.
The P0345 indicates that there is a serious problem with your vehicle, one that can greatly affect your engine’s performance and drivability. If you encounter this code, you’ll need to address it right away. It can cause bigger issues like engine damage if it’s disregarded.
