Here's a breakdown of why this is happening and possible solutions:
* Electronic Throttle Body (ETB): The throttle body on your Titan is electronically controlled. When you press the accelerator pedal, a sensor sends a signal to the engine control module (ECM). The ECM then sends a signal to the ETB, which opens and closes the throttle blade to regulate airflow to the engine.
* Troubleshooting:
* Check the throttle position sensor (TPS): The TPS measures the position of the throttle blade and sends this information to the ECM. A faulty TPS can prevent the engine from responding properly to the accelerator pedal. You can have the TPS checked or replaced by a mechanic.
* Inspect the wiring and connectors: Look for any loose or damaged wiring between the throttle pedal, TPS, and ECM.
* Scan for diagnostic trouble codes (DTCs): Use an OBD2 scanner to check for any error codes related to the engine or throttle control system. These codes can provide valuable information about the problem.
* Inspect the ETB: While less common, the ETB itself can fail. This often requires a replacement.
Important Note: If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic for diagnosis and repair.
Remember: Never attempt to adjust or tamper with the electronic throttle system without proper knowledge and tools. Doing so can potentially damage the system or create unsafe conditions.
