Feb 24, 2021 · First 5min it drove a little odd, with some slightly off shifts and the feel of very very miniscule surging while driving steady, like if i was just slightly goosing the pedal an extra tenth of a percent. Hit the highway for a couple miles and it was fine after. Idle was noticeably smoother. Checked for the pending codes and they were gone.

Apr 19, 2006 · I got trouble codes P0121 and P0221 which indicate that the ECM is not getting a signal from the throttle position sensors. The easy fix is to replace the throttle body. The expensive fix is to take the car to the dealer and have them fix it. since my car is no longer under warrenty i'd like to avoid the dearer if I can.

Dec 19, 2024 · Diagnostic trouble code (DTC) P0221 stands for “Throttle/Pedal Position Sensor/ Switch B Circuit Range/Performance Problem.” A “range” or “performance” problem typically means that the sensor in question doesn’t always agree with the other redundant sensors.

The P0221 Cadillac diagnostic trouble code (DTC) relates to the Throttle Position Sensor 2 Performance. This means that the engine control module (ECM) has detected an issue with the performance of the throttle position sensor (TPS) 2.

p0221 The TP sensor 2 disagrees greater than 9 percent from TP sensor 1, or TP sensor 2 disagrees greater than 9 percent from the predicted value for greater than 1 second or a cumulative of 10 seconds.

These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM.

The P0221 DTC code may result from a number of sources, including: Faulty Throttle Position Sensor (TPS): The most common cause of P0221 is a malfunctioning TPS, which can send incorrect signals or fail to send any signals to the ECM.

The diagnostic trouble code P0221 indicates a potential issue with the throttle/pedal position sensor or switch 'B'. This sensor is responsible for monitoring the position of the throttle pedal and transmitting this information to the engine control module (ECM).
