Toyota overbearing 2.7 stepped on the gas pedal and the gas pedal didn't respond.

Check the intake system of the engine. If the air filter is too dirty, there will not be enough fresh air to enter the engine for combustion. In addition, check the intake air flow sensor of the engine. If the sensor signal is inaccurate, the control computer cannot accurately control the fuel injection quantity. Finally, check the throttle position sensor.

Security risks:

The necessary condition for the normal operation of the engine is not only sufficient oil supply, but also air. The air filter or throttle system is blocked, which will cause insufficient air intake.

Check the circuit system: the internal combustion engine needs a spark plug to ignite the fuel entering the engine, so the quality of the spark plug directly affects the ignition state. Spark plugs are consumables and need to be replaced after running for a fixed number of kilometers.
