What is C0E97?

The DTC code C0E97 signifies a problem related to the vehicle's powertrain communication network, particularly in models such as the 2015-2018 Honda Civic. This code can indicate that the engine control module (ECM) is having difficulty communicating with other important modules, such as the transmission control module (TCM) or the body control module (BCM). When this code is triggered, the vehicle may exhibit various symptoms, including performance issues or the check engine light illuminating. The implications of this code can vary from minor inconveniences to significant safety concerns, depending on the extent of the communication failure. Car owners should take this code seriously, as it can lead to poor vehicle performance, increased fuel consumption, or even complete engine shutdown in severe cases. In many instances, the issue may stem from faulty wiring, corroded connectors, or a malfunctioning module itself. Therefore, proper diagnostics are crucial to identify the exact cause and implement the necessary repairs. Ignoring this code could lead to more extensive damage and costly repairs down the line, making it essential for vehicle owners to address it promptly.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0E97 is present:

Check engine light stays on constantly, indicating a persistent issue that needs investigation.
Engine hesitates during acceleration, leading to a frustrating driving experience and potential safety risks.
Fuel economy decreased by 10-15%, which can significantly impact your wallet over time.
Transmission may shift erratically, resulting in a less smooth driving experience.
Electrical components such as lights or dashboard indicators may function improperly due to communication failures.

Possible Causes

Most common causes of C0E97 (ordered by frequency):

{'cause': 'Faulty wiring or connectors (60%) - Damaged or corroded wires can interrupt communication between modules.', 'details': 'Inspect wiring harnesses for frays, breaks, or poor connections that may cause signal loss.'}
{'cause': 'Malfunctioning ECM or TCM (25%) - A software glitch or hardware failure in the control modules can trigger this code.', 'details': 'Consider updating the software or replacing faulty modules if diagnostics indicate their malfunction.'}
{'cause': 'Environmental factors (10%) - Moisture, dirt, or extreme temperatures can affect electrical connections.', 'details': 'Ensure that all connectors are sealed and protected from the elements to prevent issues.'}
{'cause': 'Less common but serious - A failing battery or alternator can lead to inconsistent power supply to modules.', 'details': 'Test the battery and charging system to ensure they are functioning properly.'}
{'cause': 'Rare but possible - Faulty sensors can send incorrect data, leading to communication errors.', 'details': 'Check if any sensors related to engine management are malfunctioning or need replacement.'}
