This code means there's a problem with the car's computer that controls how much gas the engine gets. It's like if your game console's controller wasn't working right.
The code indicates an issue with the electronic throttle control system, specifically a fault in the processor that monitors the throttle's position and operation.
P1680 is triggered when the Electronic Throttle Control (ETC) system detects a fault in the ADC (Analog to Digital Converter) processor. This processor is responsible for converting the analog signals from the throttle position sensor into digital signals that the engine control module (ECM) can process. A fault here can lead to incorrect throttle operation.
• Check Engine Light is on
• Poor engine performance
• Vehicle may not accelerate properly
• Faulty throttle position sensor
• Wiring issues or poor connections
• Defective ECM or ADC processor
ADC: Analog to Digital Converter
ECM: Engine Control Module
ETC: Electronic Throttle Control
• Check for other related codes
• Inspect the throttle position sensor and wiring
• Test the ECM and ADC processor for faults
• Replace the throttle position sensor if faulty
• Repair or replace damaged wiring
• Replace the ECM if necessary
• OBD-II scanner
• Multimeter
• Throttle position sensor tester

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect and clean throttle body
• Ensure all electrical connections are secure
• Perform routine maintenance checks
Engine Performance
• Do not ignore the Check Engine Light
• Avoid hard acceleration until repaired
Check vehicle warranty for coverage on ECM and throttle system components.
P1680 has been a common code in vehicles with electronic throttle control systems, particularly in models from the early 2000s.
High – This issue can affect vehicle drivability and safety.
Driving with a malfunctioning throttle control system can be dangerous. Address the issue promptly.
• Engine running
• Vehicle at operating temperature
The throttle position sensor is typically located on the throttle body, near the intake manifold.
Q: Can I drive with a P1680 code?
A: It's not recommended, as it can affect vehicle performance and safety.
Q: Will a P1680 code cause my car to stall?
A: Yes, it can cause stalling or poor acceleration if not addressed.
