Code P1E67 Buick Description

The Hybrid/Electric Vehicle battery pack contains 288 cells. Groups of three cells are welded together in parallel. There are a total of 96 cell groups in the hybrid/EV battery pack assembly. These cell groups are electrically connected in-series. Each individual cell group is rated at 3.7 V, for a nominal system voltage of 355 V direct current. The battery cells are also grouped together into three sections. The first 90 cells/30 cell groups make up battery section one. This section is adjacent to the cowl and contains batteries 67 through to 96. Battery section two is located behind section one. It is made up of 72 cells/24 cell groups and contains batteries 43 through to 66. The transverse battery section is section number three, it is made up of the remaining 126 cells/42 cell groups and contains batteries 1 through to 42. The three battery sections are individually serviceable components.
The battery energy control module monitors the voltage of the 96 battery cell groups through the four hybrid/EV battery interface control modules. Voltage sense circuits are attached to each individual cell group, and these sense circuits terminate at a connector located on the top surface of the battery section. A serviceable auxiliary battery wiring harness joins this connector to a hybrid/EV battery interface control module, also located on the top surface of the battery section. The hybrid/EV battery interface control module encodes the voltage reading and transmits it to the battery energy control module through the battery control harness. There is one hybrid/EV battery interface control module located on battery sections one and two, and two hybrid/EV battery interface control modules associated with battery section three. The hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module are all considered serviceable components.
The battery energy control module will determine when a fault condition is present. Diagnostics and system status are communicated from the battery energy control module to hybrid/EV powertrain control module 2 through serial data. The hybrid/EV powertrain control module 2 is the host controller for diagnostic trouble code information.

Frequently Asked Questions about P1E67 Buick Code

What does the OBDII code P1E67 mean on a Buick?

The P1E67 code refers to an issue with the Hybrid/Electric Vehicle Battery 60 Circuit, typically indicating a fault in the high-voltage battery monitoring system.

What are the common symptoms of code P1E67?

Symptoms may include an illuminated check engine light, reduced hybrid or EV performance, limited driving range, or the vehicle switching to a limp mode.

What causes the P1E67 code to appear?

Possible causes include a malfunction in the high-voltage battery sensor, damaged or corroded wiring in the battery circuit, or a defective battery module.

Can driving with the P1E67 code damage my vehicle?

Yes, continuing to drive with this code can lead to further electrical or battery damage and reduced vehicle performance. Itâ€™s best to address the issue promptly.

How do I diagnose the P1E67 code?

Diagnosis involves scanning the vehicle with an OBDII tool, inspecting the high-voltage battery wiring and connectors, and testing the battery sensor for faults.

Can I fix the P1E67 code myself?

If the problem is minor, like a loose connection, you might be able to fix it. However, dealing with high-voltage components is dangerous, so professional repair is recommended.

Does the P1E67 code mean I need a new battery?

Not necessarily. The code may be triggered by a sensor or wiring issue rather than a failed battery. A proper diagnosis is required to determine the exact cause.

How much does it cost to repair the P1E67 code?

Repair costs can vary widely, ranging from $100 to $500 for wiring or sensor repairs, but replacing a high-voltage battery module could cost significantly more.

What tools are needed to diagnose the P1E67 code?

Youâ€™ll need an advanced OBDII scanner capable of reading hybrid or EV-specific codes, and possibly a multimeter to test wiring and connectors.

Can a software update fix the P1E67 code?

In some cases, a software update for the vehicleâ€™s powertrain control module (PCM) or battery management system (BMS) can resolve the issue if itâ€™s caused by a programming error.
