What Happens When a Transmission Range Sensor Goes Out

Have you ever been driving down the road, minding your own business, when suddenly your car starts acting up? Perhaps the engine begins to sputter or a warning light appears on the dashboard. But, have you ever considered what might happen if your transmission range sensor goes out? This is one of those issues that can easily go undetected until it’s too late.

Imagine you’re running late for an important meeting and suddenly your car stops responding as it should. The gears start to slip and shift erratically, making it difficult to maintain control. You may even find yourself stranded on the side of the road with no idea what went wrong. This is just one of the many frustrating scenarios that can arise from a faulty transmission range sensor.

But fear not! With some knowledge and preparation, you can avoid these situations altogether. In this article, we will explore in-depth what happens when a transmission range sensor goes out, why it’s important to address the issue promptly, and how to identify signs of trouble before they become major problems. So buckle up and get ready to learn!

What is a Transmission Range Sensor and What Does it Do?

A transmission range sensor (TRS) is also known as a neutral safety switch. It sends signals to the powertrain control module (PCM) and lets the computer know which gear your vehicle is in. The TRS can be located on the side of the transmission or directly under the shift console. It works by monitoring the shifter’s position to ensure that you can’t start your engine unless your car is in either neutral or park.

The TRS also helps to regulate several other functions in the vehicle such as cruise control, reverse lamps, and backup cameras. It prevents drivers from starting their cars while they are still in gear, causing accidents. The sensor ensures that only when you’re parked or in neutral will you be able to start the ignition.

How does a transmission range sensor work?

When you move your car’s shift lever from “park” to any other gear, it tells a small computer called TCM about the new selection. The TCM then sends an electrical signal to activate a solenoid valve within the transmission. The valve directs hydraulic fluid to either engage or disengage gears as needed.

The TRS provides feedback about what gear has been selected by sending a voltage signal back to the TCM based on how much current flows through its circuits. This signal tells TCM if it should allow shifting into another gear or not.

How important is a transmission range sensor?

In vehicles with automatic transmissions, this component plays a vital role in ensuring safety and preventing damage to both driver and car alike.
Without this sensor, it would be possible for someone to accidentally put their foot onto the gas pedal while still in reverse, putting themselves and others at risk of injury or accident.

Signs Your Transmission Range Sensor is Going Out

As with any component in a vehicle, the TRS can wear out over time. Here are some common signs to look for when your TRS is starting to go out:

• Difficulty shifting gears
• The car stalls when shifting between gears
• The engine won’t start or turn over
• The reverse lights come on while you’re driving forward
• The shifter becomes stuck in park or neutral
• Check engine light comes on

If you notice any of these symptoms, it’s best to have the transmission range sensor checked and replaced if necessary.

Common Symptoms of a Failing Transmission Range Sensor

When the TRS starts to fail, it can cause various issues that directly affect the performance of your car. Some of the most common symptoms include:

• Failure to start: The car will not start or crank at all.
• Frequent stalling: The engine may stall frequently when shifting between gears.
• Gear selection problems: You may experience difficulty shifting gears or find that your car gets stuck in one gear.
• Reverse light indicator problems: The reverse lights may stay on even when you’re driving forward.

If you are experiencing any of these symptoms, take your vehicle into a mechanic as soon as possible.

Can a Bad Transmission Range Sensor Cause Your Car to Not Start?

Yes, a failing TRS can cause your car not to start. When this component fails completely, no signal is sent to the PCM indicating what gear position has been selected. This means that the starter motor cannot be engaged because there is no way for the computer to know if the vehicle is already in drive or reverse.

Additionally, if the TRS sends incorrect signals about gear position, this can cause the engine to stall or fail to start altogether. Therefore, if you have trouble starting your car or experience any of the symptoms mentioned earlier, it’s essential to have the TRS checked immediately.

How Much Does it Typically Cost to Replace a Transmission Range Sensor?

The cost of replacing a transmission range sensor depends on the make and model of your vehicle and where you take it for repair. On average, you can expect to pay between $100 and $250 for parts and labor.

If you’re handy with cars, you might be able to replace the sensor yourself. However, if you’re not sure about your skills or lack access to tools, taking your car into a mechanic is always recommended.

Is it Safe to Drive with a Faulty Transmission Range Sensor?

It is not safe to drive with a faulty transmission range sensor. If the sensor fails entirely while driving, it could cause significant damage to other components in your vehicle and put you at risk of an accident.

Additionally, shifting gears can become difficult when the TRS starts failing. This could lead to unexpected sudden acceleration or stalling while driving, which poses severe safety hazards.

If you suspect that there’s something wrong with your TRS or are experiencing any of the symptoms mentioned above, don’t hesitate – get your vehicle inspected by a trusted mechanic as soon as possible.

Fixing a Bad Transmission Range Sensor: DIY or Professional Help?

Replacing a faulty transmission range sensor requires technical knowledge as well as some specialized tools. Therefore, unless you have experience working on cars and access to these tools, it’s best left up to professionals.

While replacing this component may seem simple in theory, there are many potential issues that could arise during installation that require expertise. Without proper knowledge or experience, even small mistakes can cause more extensive damage that will only increase repair costs over time.

Therefore we recommend that you seek professional help when it comes to replacing your transmission range sensor.

Preventative Measures to Avoid Issues with Your Transmission Range Sensor

Like any component in a car, the TRS can wear out over time. However, there are some things you can do to prolong the life of this vital piece of equipment.

• Regular maintenance: Regularly servicing your vehicle ensures that all components are checked and repaired before they become too worn or damaged.
• Avoid unnecessary gear shifting: Avoid shifting gears unnecessarily or while driving at high speeds as this will put additional stress on the TRS.
• Pay attention to warning signs: If you notice any of the symptoms mentioned earlier, take your car into a mechanic immediately for an inspection.

By following these simple steps, you can extend the lifespan of your transmission range sensor and ensure that your car continues running smoothly for years to come.

In conclusion, when a transmission range sensor goes out, it can cause various issues such as difficulty shifting gears, stalling, and even preventing the vehicle from starting altogether. It is important to address this issue promptly to avoid further damage and ensure safe driving.
