Symptoms of a Bad Honda Fit Throttle Body
When the throttle body of a Honda Fit is not functioning correctly, several symptoms may manifest, indicating potential issues with the air-fuel mixture and engine performance. These symptoms include:
1. Acceleration Issues: A malfunctioning throttle body can lead to acceleration issues, causing the vehicle to struggle to pick up speed or hesitate when the accelerator is pressed.
2. Engine Performance and Fuel Efficiency: Fluctuations in RPM, poor performance, and a drop in fuel efficiency can be indicative of a bad throttle body.
3. Check Engine Light: An illuminated check engine light can be a sign of a bad throttle body, indicating potential disturbances in the air-fuel ratio and engine performance.
4. Rough Idling and Engine Misfires: A bad throttle body may cause rough idling, stalling, and rare cases of misfires and rough running.
5. Fuel Consumption and Idle Fluctuations: Changes in fuel consumption and fluctuating idle may also be observed as symptoms of a failing throttle body.
It’s important to address these symptoms promptly to prevent severe impacts on the engine’s performance and overall vehicle operation.

Will disconnecting battery reset throttle position sensor?
Will disconnecting a battery reset a throttle position sensor? It will reset you computer on you car. A TPS is just a pot resistor, it will give a value to the computer to what it reads. If it has corrosion or damage to the sensor then it will post that and the computer will set a code.
Should I replace throttle position sensor or throttle body?
In newer vehicles, the throttle position sensor is built into the throttle body. The sensor isn’t serviced. If it develops a problem, the entire throttle body will need replacement.
What symptoms does a bad throttle body cause?
Symptoms of a Bad or Failing Throttle Body
- Grime buildup. A throttle body can easily get coagulated with dirt and grime.
- Electrical problems.
- Airflow disruptions.
- Poor or high idle.
- Worn-out Butterfly valve.
- The ominous check engine light.
- Lack of Power.
- Issues while accelerating.
How do I know if I need a new throttle position sensor?
The most common symptom is your check engine light. This indicator is a vague symptom, as it could also point to a variety of issues, but you can expect to see it if there’s any issue with your throttle position sensor. Next, any unusual changes in your acceleration could be linked to this sensor.
Is it better to replace a throttle body or clean it?
Throttle bodies get clogged rather easily and when they wear out or fail, they are expensive to replace. If you can spray some cleaner into them (there are videos on the Internet on how to do this) and have them perform better, so be it.
What happens when throttle position sensor goes bad?
Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off. On the other hand, it can also cause your car to have spontaneous accelerations even if you didn’t step on the gas.
Will a dirty throttle body throw a code?
Yes, a dirty or defective throttle body can send your car into limp mode and give a P0720 error code. The throttle body is a valve that controls the amount of air that flows into the engine.
Will cleaning a throttle body fix it?
Cleaning the throttle body properly will help improve the idle, acceleration, fuel efficiency, and any potential issues with stalling. Your car will drive smoother and more efficiently and you will be saving money on fuel so it is definitely worth the investment of time and energy into cleaning the throttle body.
How do you test a throttle body?
If the OE permits a manual check, remove the throttle body and see if you can move the throttle plate easily with your finger. There should be little to no resistance to movement. If you feel any while moving the throttle plate through its range of motion, replace the throttle body.
How do I know if my throttle body needs cleaning?
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.
