Laymans terms

This code means there's a problem with a sensor that helps the car's computer know the position of a part inside the engine called the camshaft. It's like the computer can't hear the sensor very well.

Explanation

The P23ED code is triggered when the engine control module (ECM) detects a low signal from the camshaft position sensor B on bank 1. This sensor helps the ECM determine the position of the camshaft to control the timing of the engine.

Technical description

The camshaft position sensor B on bank 1 is responsible for monitoring the position of the camshaft and sending this information to the ECM. If the signal is lower than expected, the ECM may not be able to accurately control the engine timing, leading to performance issues.

Symptoms

• Check Engine Light illuminated

• Poor engine performance

• Engine may stall or hesitate

Common Causes

• Faulty camshaft position sensor

• Wiring issues such as shorts or open circuits

• ECM malfunction

Glossary
