Hi there,
When the check engine light is on and your vehicle is not accelerating beyond 2 miles per hour shows a severe issue that requires immediate attention. The "limp Mode" check engine light shows up to protect the engine from serious damage. Here are several possible reasons why:
1. Throttle system malfunction. If the throttle body is stuck closed or not responding to inputs from the accelerator pedal. It could be due to a bad throttle position sensor, a bad throttle actuator, or some wiring issue.
2. Engine management issue. A misfiring engine (bad spark plugs, bad ignition coils, and others) and fuel system issues (clogged fuel filter or bad fuel pump assembly) could trigger the nonresponse of the engine.
3. Transmission issues. If your vehicle is an automatic transmission, a malfunction of any components inside will restrict engine acceleration. The possible culprits are low transmission fluid, bad transmission solenoids, or other critical components.
Still, it is best to have your vehicle checked and diagnosed properly by a certified mechanic or auto repair shop to find all the sources of the problem. I hope this helps!
