Hybrid/EV Battery Temperature Sensor E Circuit Low

29 brands affected · Generic SAE J2012 description.

Key terms: Control module: a small computer that runs one part of the car · SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

Safety: This code relates to the battery temperature. A hot or poorly cooled battery can lose power, and a damaged battery carries a fire risk.

1What it means in plain English

The engine or powertrain control system has stored a fault that does not have specific guidance in this database yet.

2Common causes

Sensor or actuator fault
Wiring or connector fault
Vacuum or intake leak
Fuel or ignition problem
Control module fault

3Can I drive?

Caution · drive with care

Watch for a battery temperature warning. If the warning is on, stop safely and let the battery cool; do not charge a hot battery and have it checked.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
