- Engine won’t idle smoothly, idles too slowly, or stalls.
- Car accelerates, but won’t exceed a relatively low speed, or shift up.

How much does it cost to replace a throttle position sensor?

Can you drive with a bad throttle position sensor?
Can you drive with a bad throttle position sensor? It is not a good idea to drive with a bad throttle position sensor. Driving your car in this condition can be dangerous because your car might not accelerate properly or could suddenly accelerate without the driver pressing the gas pedal.
Is it OK to drive with a bad throttle position sensor?
What is the code for a bad TPS?
Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage. Depending on your vehicle, your TPS lower output voltage limit should be around .
What happens if you don’t do a throttle body relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle.
Where is the TPS on a Subaru Outback?
The TPS can be seen in the picture. It is mounted on 2 slotted screws so it can be rotated about the throttle position for adjustment. I marked it’s original position with a knife (for accuracy!), and then moved it just a knife-blades clockwise (i.e. so the throttle would have to be a little more closed for the same TPS response).
What should TPS be on Subaru Impreza Legacy?
Let me know how this works out. The manual I think says to adjust TPS output to .45V to .55V (ideal .5V) at idle. I did see an article on EndWrench.com for the Impreza (not that it applies to the Legacy or Outback) to adjust the TPS only with the engine warm.
How to reset the tire pressure on a Subaru Forester?
How the vehicle drives. Increases the need for fuel. Tire failure. Refer to the Manufacturer’s Sticker located on the inside of the Driver’s door. Fill each tire to the recommended PSI/air pressure. NOTE: If you are unable to Reset the Tire Pressure Warning Light on the first try, REPEAT the steps.
Do you need to adjust the TPS on an Impreza?
They do not need to be adjusted. The ECU takes a reading at every startup and calibrates that as the throttle closed position. Great to know. I recently swapped a throttle body because I had stolen the TPS from the intake that I needed to use and didn’t know how to reset the TPS if I just replaced it.
