What Does P0221 Code Mean?
Fault Code Definition
The Throttle Position Sensor/Switch is located on the Throttle Body of the Intake Manifold and the Pedal Position Sensor/Switch is located on the Accelerator Pedal. These sensors provide precise input from the driver's foot in terms of how much power is needed—and how urgently—from the engine.
As the Throttle Position Sensor is rotated from its base resting position to full acceleration, it sends a decreasing voltage signal to the Powertrain Control Module (PCM). This decreasing or increasing voltage signal is used by the PCM to manage the Air Fuel Ratio and Spark Timing of the engine as well as other emissions system components.
P0221 Symptoms
- Check Engine Light will illuminate
- In many cases, no abnormal symptoms may be noticed
- In some cases, the engine may be hard starting
- In some cases, the engine may hesitate during acceleration
Common Problems That Trigger the P0221 Code
- Defective Throttle/Pedal Position Sensor or Switch
- Dirty or carbon-filled Throttle Bore
- Torn or jammed floor mats
- Faulty or corroded Throttle/Pedal Position Sensor/Switch wiring or connections
Common Misdiagnoses
- Throttle Position Sensor is replaced when the real problem is a dirty or carbon-filled Throttle Body
- Throttle/Pedal Position Sensor is replaced when the real problem is a poor connection or chafed wiring
- Pedal Position Sensor is replaced when the real problem is torn or damaged floor mats
I just bought a 2014 Jeep Patriot , the throttle
sensor warning light keeps going off and stalls
out quite a bit and getting worse . Took it to a
mechanic twice and the car will run fine for a week
or so then acts up . Mechanic changed
throttle
sensor and gas paddle , do i need to inform them
to look at fuel pump and or fuel injectors being the
problem is still on going ?

How much does a Jeep Patriot throttle body sensor replacement cost?
An internal combustion engine requires a mixture of air and fuel to provide the energy for combustion. The air-to-fuel ratio needs to be correct for your Jeep Patriot’s engine to run smoothly and to deliver a prompt response to your driving throttle demands.
The amount of throttle being requested by the driver is monitored by a throttle position sensor (TPS) which determines the airflow through the Jeep Patriot’s throttle body. The throttle position sensor plays a crucial part in the Jeep Patriot’s engine management system and if it fails, the check engine light may appear and you may notice engine misfire and/or poor performance.
The throttle position sensor is usually situated next to the Jeep Patriot’s throttle body. In some cases, it connects with the butterfly spindle to monitor the throttle position. However, on ‘drive-by-wire’ or electronic throttle control (ETC) systems it can also control the throttle position. It controls the rate and volume of airflow into the engine.
Anytime the air/fuel mixture might be incorrect on a Jeep Patriot it is a cause for concern and the problem should be rectified as soon as possible. There is the chance of engine damage if this issue is left for too long, and driving an unhappy Jeep is never a relaxing drive.
