This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car is getting a signal that is too high from a sensor that checks the position of a part called the camshaft on one side of the engine.
The engine control module (ECM) is detecting a higher than expected voltage signal from the camshaft position sensor on Bank 2, which could indicate an electrical issue or sensor malfunction.
P23EB indicates that the signal voltage from the camshaft position sensor 'A' on Bank 2 is higher than the expected range. This could be due to a short circuit, a faulty sensor, or an issue with the ECM receiving the signal.
• Check Engine Light is on
• Poor engine performance
• Engine misfires
• Faulty camshaft position sensor
• Wiring issues such as short circuits or open circuits

Sensor Issue
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional if unsure
• Regular maintenance can prevent sensor issues
Check with the vehicle manufacturer for specific warranty coverage on sensors and ECM.
This code has been associated with camshaft position sensor issues in various vehicle models, often due to wiring problems.
Moderate – It is important to address this issue to prevent potential engine performance problems.
Driving with a malfunctioning camshaft position sensor can lead to engine performance issues which may affect vehicle safety.
• Engine at normal operating temperature
• Vehicle stationary and in park
The camshaft position sensor is typically located near the camshaft on the engine, on Bank 2 which is the side of the engine opposite to Bank 1.
Q: What does Bank 2 mean?
A: Bank 2 refers to the side of the engine that does not contain cylinder 1.
Q: Can I drive with this code?
A: It's not recommended to drive for extended periods with this code as it may lead to engine performance issues.
