What is P0DD8?

The diagnostic trouble code (DTC) P0DD8 signifies an electric drive motor 'B' performance issue, commonly found in electric vehicles such as the 2017-2021 Chevrolet Bolt EV. This code suggests that the vehicle's electric drive motor is not performing within the expected parameters set by the manufacturer. It may be triggered by various factors including issues with the motor itself, problems with the power electronics module, or even battery supply problems. When this code appears, the vehicle may exhibit reduced power, longer acceleration times, or even fail to operate altogether in severe cases. Owners may notice the 'Check Engine' light illuminate or experience a decline in overall driving performance. The implications of ignoring this code can be significant, leading to further damage and costly repairs. It is essential to address this issue promptly to ensure the optimal performance of your electric vehicle and to avoid the risk of complete power loss while driving.

Symptoms

Common symptoms when P0DD8 is present:

  • Check engine light stays on constantly, indicating an underlying issue that requires immediate attention.
  • Reduced acceleration power, making it difficult to merge into traffic or climb hills.
  • Increased power consumption, leading to a noticeable decrease in electric range, potentially by 20% or more.
  • Unusual noises from the electric drive motor, such as grinding or whining, which may indicate mechanical failure.
  • Vehicle may enter 'limp mode,' restricting speed and power to protect the electrical system.

Possible Causes

Most common causes of P0DD8 (ordered by frequency):

  1. Faulty electric drive motor (60% likelihood) - The most common reason for the P0DD8 code is a malfunction in the electric drive motor itself, which can result from wear and tear or manufacturing defects.
  2. Power electronics module failure (20% likelihood) - This module is critical for regulating the motor's performance, and issues here can lead to the P0DD8 code being triggered.
  3. Battery pack issues (15% likelihood) - Inadequate voltage supply from the battery can impact the motor's performance.
  4. Wiring or connector problems (4% likelihood) - Damaged or corroded connections can interrupt the signal and power flow to the motor.
  5. Rare software glitches (1% likelihood) - Occasionally, software bugs in the vehicle's control module can erroneously trigger this code.
