This code means there's a problem with the car's electric system that helps start the engine. It's like when a toy's battery doesn't work right, so the toy doesn't start properly.

Explanation

The code P1E14 indicates an issue with the sensor that measures the current in the W phase of the high voltage starter generator. This sensor is not reading correctly, which affects the performance of the starter generator.

Technical description

The P1E14 code is triggered when the powertrain control module (PCM) detects a range or performance problem with the current sensor circuit of the W phase in the high voltage starter generator. This could be due to a faulty sensor, wiring issues, or problems with the starter generator itself.

Symptoms

• Check Engine Light is on

• Difficulty starting the vehicle

• Reduced engine performance

Common Causes

• Faulty current sensor

• Damaged wiring or connectors
