Frequently Asked Questions

Can I drive with error code P2116?
It's not recommended. The vehicle may enter limp mode with reduced power, or the throttle may not respond properly, which can be dangerous.
What does 'throttle position sensor E' mean?
Many modern throttle bodies have multiple sensors (e.g., A, B, C, D, E) for redundancy. 'E' usually refers to one of the sensors, often sensor 2 or a feedback sensor.
How much does it cost to fix P2116?
DIY cost: $30-$150 for parts (throttle body or sensor). Professional repair can cost $200-$600 depending on labor and parts.
Will cleaning the throttle body fix P2116?
Yes, if the issue is carbon buildup causing the sensor to read incorrectly. If the sensor itself is faulty, cleaning won't help.
What vehicles commonly get P2116?
This code is common in many makes but is especially reported on some Honda, Toyota, and Ford models with electronic throttle control.
