This code means there's a problem with the car's system that controls how much power the engine makes. It's like when a toy car's remote control isn't working right, and the car doesn't go as fast as it should.
The P1679 code indicates an issue with the electronic throttle control system, specifically related to the calculation of torque loss at levels 2 or 3.
The electronic throttle control (ETC) system monitors the throttle position and adjusts it to ensure optimal engine performance. The P1679 code is triggered when the ETC system detects an anomaly in the torque loss calculation, indicating a potential issue with the throttle control system's ability to accurately manage engine power.
• Reduced engine power
• Check engine light is on
• Poor acceleration
• Faulty throttle position sensor
• Wiring issues in the throttle control circuit
• Malfunctioning electronic throttle body

Torque: A measure of the rotational force produced by the engine.
• Check for other related codes
• Inspect the throttle position sensor and wiring
• Test the electronic throttle body for proper operation
• Replace the throttle position sensor if faulty
• Repair or replace damaged wiring
• Replace the electronic throttle body if necessary

Moderate
• Ford Focus
• Chevrolet Malibu
• Toyota Camry
• Regularly clean the throttle body
• Perform routine maintenance checks
• Ensure wiring connections are secure
Engine Performance
• Avoid driving aggressively until the issue is resolved
• Schedule a diagnostic check with a professional mechanic
Check with the vehicle manufacturer for specific warranty coverage on electronic throttle components.
This code has been more prevalent in vehicles with high mileage or those that have not received regular maintenance.
Moderate – It's important to address this issue to prevent further engine performance problems.
Ignoring this code may lead to reduced vehicle performance and could affect safety if not addressed promptly.
• Vehicle at operating temperature
• Engine running and idling
The electronic throttle control system is typically located on the engine's intake manifold.
Q: Can I drive my car with a P1679 code?
A: It's possible to drive, but you may experience reduced power and performance. It's best to have it checked soon.
Q: Will the check engine light turn off after fixing the issue?
A: Yes, once the issue is resolved and the code is cleared, the check engine light should turn off.
