What repairs can fix the P0121 code?
Repairing or replacing the TPS connector.Repairing the wiring as necessary.Replace the TPS with a new sensor.
What causes a P0121 code?
When code P0121 occurs, it means that your Engine Control Module (ECM) recognized that your throttle position “A” circuit’s expected output voltage has either gone above or below the sensor’s expected range. When code P0121 is triggered, your ECM will go into failsafe mode.
How serious is a throttle position sensor?
If left unattended, the faulty throttle position sensor might cause your car to shake heavily. This in turn will put a lot of pressure on the motor and transmission mount, eventually causing it to give out and requiring you to fork out additional money, to repair these issues as well.
What code is a bad throttle body?
A faulty throttle body is one of the common causes of code P0121.
How much is a TPS sensor?
The average replacement cost for the throttle position sensor is anywhere from $110 to $200. The parts cost is anywhere from $75 to $105 while the labor cost is anywhere from $35 to $95.
Where is the throttle pedal position sensor located?
A throttle position sensor (TPS) is a sensor used to monitor the air intake of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle.
What happens when you unplug throttle position sensor?

What would cause a throttle position sensor to keep going bad?
Code errors can cause your throttle position sensor to work erratically or incorrectly. Otherwise, you’ll need professional software to reprogram your sensor. This job is best done by a professional mechanic. If your sensor just needs repairs, it could be the result of faulty or loose wiring.
What are the symptoms of a defective throttle position sensor?

#1. Rough Idling. #2. Check Engine Light Illuminated. #3. Frequent Engine Stalling. #4. Poor Fuel Economy. #5. Limp Mode Activated. #6. Difficulty Shifting Gears. #7. Weak Engine Performance.
What happen if throttle body is dirty?
When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling. With the use of a throttle body cleaning product, the dirt and debris buildup are easily removed.
Should I clean or replace throttle body?
While throttle-body cleaning is good preventative car maintenance, it should also help engine drivability. In fact, if you’ve noticed a rough idle, stumbling initial acceleration or even stalling – all when the engine is fully warmed up – a dirty throttle body could be the culprit.
