This usually results in:
* Reduced power: The engine won't produce its full horsepower. Acceleration will be sluggish.
* Limited RPM: The engine might not rev as high as normal.
* Possible transmission limitations: Shifting may feel different or be restricted.
* Check Engine Light (CEL): This light will almost certainly be illuminated on the dashboard.
The fail-safe mode is a protective measure. It's *not* a permanent condition. You must have the vehicle diagnosed by a mechanic as soon as possible to identify and repair the underlying problem. Driving indefinitely in fail-safe mode could cause additional damage or lead to a complete engine or transmission failure. The diagnostic trouble codes (DTCs) stored by the PCM will be crucial in pinpointing the issue.
