Frequently Asked Questions
What does P2114 mean?
P2114 means the electronic throttle control system has detected that the throttle plate is stuck in an open position. This is a safety-critical condition as the engine speed cannot be properly controlled.
Is P2114 dangerous?
Yes. A stuck-open throttle is a safety hazard. The engine may race uncontrollably. Turn off the engine immediately, shift to neutral if needed, and have the vehicle towed to a repair shop.
How much does it cost to fix P2114?
Repairs typically cost $300 to $700. The most common fix is throttle body replacement at $300-$600. In rare cases where the return spring is the only issue, repair costs may be lower.
