Description:

This diagnostic trouble code indicates that both throttle sensor 1 and throttle sensor 2 are open, which suggests a failure in the dual throttle system. This can impact the proper functioning of the throttle and engine control.

Reaction:

The vehicle may experience throttle control issues, potentially leading to reduced performance or erratic throttle behavior.

Recommendations:

  • Inspect Throttle Sensors and Wiring: Check for damaged, frayed, or loose wiring and connectors associated with throttle sensor 1 and throttle sensor 2. Repair or replace as necessary.
  • Test Throttle Sensors: Use diagnostic tools to test the functionality of throttle sensor 1 and throttle sensor 2. Ensure that both sensors are operating correctly and providing accurate readings.
  • Check for Sensor Calibration: Verify that the throttle sensors are properly calibrated. Recalibrate if necessary to ensure accurate sensor readings.
  • Verify Throttle Mechanism: Inspect the throttle mechanism for any physical obstructions or damage that could cause the sensors to remain open.
  • Reset ECU and Monitor System: After resolving the issue, reset the ECU to clear the fault code and monitor the system to ensure normal operation.

Note:

Maintaining proper function and calibration of throttle sensors is crucial for accurate engine control and performance. Regular inspections and timely maintenance can help prevent throttle-related issues.
