Laymans terms

This code means that the car's computer has detected a problem with the electric pump that helps cool down the electronics in a hybrid or electric vehicle. It's like if a fan in your computer stopped working.

Explanation

The P2E41 code indicates an issue with the control circuit for the second electronics coolant pump in a hybrid or electric vehicle. This could be due to an open circuit, which means the electrical path is broken.

Technical description

The P2E41 code is triggered when the vehicle's powertrain control module (PCM) detects a malfunction in the control circuit for the Hybrid/EV electronics coolant pump B. This could be due to an open circuit, faulty wiring, or a defective pump.

Symptoms

• Check Engine Light is on

• Overheating of hybrid/EV electronics

• Reduced vehicle performance

Common Causes

• Faulty electronics coolant pump B

• Open or shorted wiring in the pump circuit

• Bad connection or corrosion in the pump's electrical connector
