What is OBD-II Code P23EE – Camshaft B Position Signal Output Circuit High Bank 1

Easily understanding OBD-II Codes can be a challenge for most vehicle owners. OBD, or On-Board Diagnostics, is an onboard computer system that monitors and evaluates a vehicle’s performance and issues from the engine, transmission, and emissions systems. P23EE is one of the many OBD-II codes that your car might show up, indicating that there is a problem with the camshaft sensor.

In this article, we’ll take a closer look at OBD-II Code P23EE – Camshaft B Position Signal Output Circuit High Bank 1 and what it means, the common causes of this issue, and how to fix it.

What is OBD-II Code P23EE – Camshaft B Position Signal Output Circuit High Bank 1?

When your vehicle’s check engine light is illuminated, it’s trying to communicate to you about a problem in the car, and OBD-II Code P23EE refers to an issue with the camshaft position sensor on bank 1. Bank 1 is usually located on the same side as the No.1 cylinder.

The Camshaft Position Sensor tells the engine computer where the cam is in its rotation, allowing it to adjust fuel injection and ignition timing. When the output signal circuit for Bank 1 is higher than it should be, the code P23EE is triggered resulting in an illuminated check engine light. This usually happens when the electrical wiring in the camshaft sensor circuit is malfunctioning, or there is a problem with the sensor itself.

What Causes the Camshaft B Position Signal Output Circuit High Bank 1 Error Code?

Several issues can trigger the P23EE trouble code which includes:

1. Faulty Camshaft Position Sensor: This is the most common cause of a malfunctioning camshaft sensor. They usually fail due to age, wear and tear, or physical damage.

2. Wiring Connection Problems: Damage to wires or loose connections in the wiring can prevent the Camshaft Position Sensor’s electrical system from transmitting the signal properly.

3. Faulty ECM: Issues with the Engine Control Module is another probable cause of code P23EE. An ECM controls everything in an engine management system and regulates sensors.

4. Damaged Timing Chain: A damaged or loose timing chain can cause issues with the camshaft position sensor which may lead to the P23EE code.

What Are The Symptoms of OBD-II Code P23EE?

The symptoms of the code P23EE may include the following:

1. Check Engine Light Illuminated: The most obvious symptom of the P23EE code is the illuminated Check engine light.

2. Rough Idling: Your car may produce a rough idle, shaking, or experiencing power loss while driving.

3. Stalling: The engine could stall while driving or coming to a halt due to the Camshaft B Position Sensor Error.

4. Ignition Failing: The ignition system might also fail to ignite when you try starting your car.

How to Fix P23EE Error Code?

To repair the P23EE OBD code, mechanics first need to use an OBD-II scanner to diagnose the issue. The following are basic repair steps to fix the problem:

1. Check the Camshaft Position Sensor: If the Camshaft Position Sensor is faulty, it needs replacement to correct the issue.

2. Check the Wiring Connection: Ensure the electrical wiring connection is tight and clean, and repair or replace any damaged wires.

3. Check the Engine Control Module: If the diagnostic code analysis suggests an ECM problem, it will need to be replaced.

4. Examine the Timing Chain: A damaged timing chain must be fixed or replaced to solve the issue.

5. Clear the Diagnostic Codes: After repairing the fault, mechanics will need to clear the fault codes using an OBD-II scanner to reset the Check Engine Light.

In most cases, addressing the cause of the P23EE error code will fix the problem with the engine.

Frequently Asked Questions

1. How can I know that code P23EE is causing my check engine light to come on?

The OBD-II scanner is a necessary tool to diagnose your check engine light problems thoroughly. After plugging it in, read the code to determine that code P23EE is causing the problem

2. How much does it cost to repair the P23EE code?

The cost of fixing code P23EE varies depending on the issue’s severity. You may end up paying between $100 and $900 for repairs.

3. Can I still drive my car with the P23EE code?

In most cases, you can drive your car with the P23EE code. However, it would help if you get the fault fixed as soon as possible to avoid detrimental engine damage.

4. If I repair or replace the Camshaft Position Sensor, will the P23EE code disappear?

Yes, repairing or replacing the Camshaft Position Sensor should clear code P23EE if it was the trigger.

5. Will the P23EE code fix itself?

No, the P23EE won’t fix itself since it’s an engine performance issue and requires adequate attention to fix it completely.


If you have any vehicle issues, it’s best to seek the advice of a professional auto mechanic who can adequately diagnose and correct the issue. Diagnosing code P23EE can be challenging, but with the OBD-II scanner’s help and a professional auto mechanic’s skills and experience, you can successfully fix the issues. Doing so early can save you from costly repairs and reduce the risk of even more severe engine damage.
