- Trouble Accelerating.
- Uneven Idle.
- Check Engine Light.
How do I know if my electronic throttle body is bad?
Here are the most common signs a failing throttle body we’ve seen in our shop:
- Grime buildup. Dirt and grime can build up inside the part’s housing (some mechanics call this “coking”) causing an interruption in air-fuel flow.
- Electrical problems.
- Airflow disruptions.
- Poor or high idle.
- The ominous check engine light.
What does the throttle position sensor TPS do?
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. More advanced forms of the sensor are also used.
What causes a throttle body sensor to go bad?
Filth, carbon, and dirt can build up in the housing creating problems with air flow. Known as coking, the normally smooth service for air to travel becomes full of gunk and creates an imbalance. This interrupts that perfect mixture of air and fuel which can cause the butterfly valve to get stuck.
How do you calibrate a throttle position sensor?

Even when your throttle body’s blade closes entirely, some air has to get through to the intake manifold.
What are the symptoms of a TPS problem?
Here are some specific symptoms you’ll see: TPS diagnostic trouble codes (DTCs) stored in the vehicle’s computer’s memory. Code 23: Throttle Position (TP) Circuit Performance Problem.

The one thing that you can definitely count on, when the TPS fails, is the check engine light shining nice and bright to let you know that there’s a Diagnostic Trouble Code stored in the fuel injection computer.
What are the symptoms of a bad throttle position sensor?
Here are some common symptoms of a bad or failing throttle position sensor to watch for: 1. Car won’t accelerate, lacks power when accelerating, or accelerates itself. It may feel as though the car simply doesn’t accelerate as it should, and jerks or hesitates as it picks up speed. It may accelerate smoothly, but lack power.
