The P1217 code is a general warning that there is an issue with the throttle or pedal position sensor. This code can appear by itself or alongside other codes. It specifically indicates that sensor switch E is receiving a weak input signal. This sensor is located on the gas pedal and is responsible for informing the ECU about the status and position of the gas pedal. When the sensor detects a weak input, it triggers the error code. Common reasons for this code include faulty electrical connections, a malfunctioning ECU, a short in the wiring system, or a defective throttle or pedal position sensor. In any scenario, the Check Engine light will illuminate when this code is triggered. Additionally, your vehicle may not respond properly to the throttle, exhibit poor acceleration, or even stall.
