The throttle body is an important part of your vehicle and should be monitored regularly. The throttle body temp sensor is a sensor that is mounted on the throttle body. It monitors the temperature of the throttle body and then sends the information directly to the engine control module. From there, the module figures out the best fuel flow for the engine.
Depending on the age of your vehicle, it can be affected in different ways should the throttle body temp sensor begin to fail. The best route of action is to have it checked out by a mechanic as soon as possible for a full diagnosis. The mechanic will need to remove the faulty throttle body temp sensor and then replace it with a new one - a repair isn't possible. This part doesn't need regular inspections or maintenance, it only needs attention once it fails.
As for failure, there are a few signs to watch for that can point to a faulty throttle body temp sensor. Let’s take a look:
When your engine is hot you may have a problem getting the engine started. This can be intermittent rather than every single time the engine is hot.
When you are idling, you may have issues with stalling since the air and fuel mixture will be off. This can begin as intermittent and then become more common as the part continues to fail. Take this as an early warning sign to get it into the mechanic and checked out.
The engine may also give you issues when you accelerate, which is not only frustrating but dangerous. Again it goes back to the improper mixture of fuel and air. In order for your engine to perform at its peak level it needs the right mixture.
Another telltale sign is if your Check Engine Light comes on. Obviously this can mean a number of different things, and among them is a faulty throttle body temp sensor.
The throttle body temp sensor is a key component in making sure your engine receives the perfect combination of fuel and air. Without that right combination the engine won’t be able to run as effectively and efficiently as it is meant to. Have a certified mechanic replace the failing throttle body temperature sensor to eliminate any further problems with your vehicle.
