How To Bypass Ambient Air Temperature Sensor

Your ambient temperature sensor is used to control your air conditioning then it switches off when your car is at the desired temperature.

The sensor allows the air-conditioning or heating to work how you want and this is why so many manufacturers use this engineering science in their cars. But if there is a problem where is the ambience temperature sensor, and how do you reset it?

Resetting your ambient temperature sensor is one of the kickoff steps you should try if you want to try and fix your sensor. Following our handy guide will prove you that the sensor is commonly located backside the grille in your engine bay and how to residue it safely by disconnecting your battery and pressing the reset button.

Bad Ambient Temperature Sensor Symptoms

Before nosotros await into the location of your ambience temperature sensor and how you can reset and bypass information technology at home, you need to make certain that information technology is the root crusade of your problems to salvage fourth dimension and free energy.

There are many symptoms you might notice if your ambient temperature sensor is not performing as expected which we have listed to requite you a better agreement.

Inconsistent Cooling

As your ambient temperature sensor has a direct office in the automatic functions of your AC organisation then this might interfere with its ability to maintain a absurd and comfy cabin temperature.

If your AC reads the ambient and cabin temperature sensors that are providing a bad reading and then this volition mean your auto Ac fashion volition not work likewise.

Check Engine Light

If you've read any of our other manufactures then you will know that a bank check engine calorie-free is a very mutual thing to run across. It is specially mutual in older vehicles and it can betoken a huge number of faults, which isn't very helpful.

If you suspect yous have issues with your ambient temperature sensor then yous might observe your bank check engine light illuminates briefly to bespeak the sensor circuit is malfunctioning and needs repair.

Poor Fuel Efficiency

The incorrect signals that your ambient temperature sensor will exist provided tin can cause your onboard computer to make an wrong signal which results in bad fuel pressure management.

The malfunctioning signal will suggest your signal is cold which results in more fuel beingness used to oestrus the engine which directly affects your functioning and fuel economy.

Overheating Engine

Your engine cooling fan makes certain it removed estrus from the engine coolant and maintains a safe engine temperature. Just this won't happen with a failing ambient temperature sensor.

The electrically operated fan works through a signal from the computer, and this signal might not happen when required and the faux signal could cause the engine to overheat.

This isn't ever the case though as some vehicles have a dissever coolant temperature sensor for the fan.

Black Exhaust Fume

Pay attention to your frazzle smoke as blackness smoke will be a sign of excess fuel beingness burnt in the frazzle pipe.

This is because the ECM may fail to brand the right air/fuel mixture and interfere with the normal combustion procedure of your vehicle.

How to Featherbed an Ambient Air Temperature Sensor

If y'all're more familiar with the inner workings of your vehicle then you lot might desire to consider bypassing your ambient temperature sensor to make a more permanent solution.

Although we practise non recommend yous do this unless you're 100% confident. As with any part of your vehicle, modifying or using aftermarket parts could lead to premature wear or future problems then make sure you think this through beforehand.

In some vehicles with an application such as FordPass, you can use this to your advantage to bypass the ambience temperature sensor. Y'all can besides apply a browse tool to check the sensor isn't failing or throwing upwardly whatever codes.

At that place are three methods for bypassing the ambient temperature sensor, so let'due south take a closer look.

Method 1

1. Open up the bombardment and locate your ambient temperature sensor.
2. Chop the black and cerise wires from the bombardment and connect ane cease of the cables to the battery.
3. And then connect the other scroll to the terminal of the battery.

Method 2

The 2nd method is simple and piece of cake enough to practice, only you should still always be cautious when working effectually and with the battery of your vehicle.

Start by wrapping the ambient temperature sensor with a piece of newspaper, and and then plug in the battery and use it as normal.

Method 3

The final method to bypass your ambience air temperature sensor is past injecting a small amount of fluid liquid crystal onto the sensor volume. As information technology is thermotropic and the change would limit the infrared rays passing through the sensor.

Use around 10ml of liquid crystal in a small-scale glass capillary and information technology volition create a transparent window that infrared rays tin can pass and this volition alter its phase according to the ambient temperature.

Where Is the Ambient Air Temperature Sensor Located?

One time you lot find the sensor, there are some safety precautions you need to take so keep reading to find out how to reset the ambient temperature sensors.

• Step 1 –Before yous starting time working with any of the electric systems, you need to remove the power to prevent safety risks then remove and disconnect your battery.
• Stride 2 –Next, uninstall the device and await for a plastic prune that attaches the sensor to the vehicle wiring.
• Footstep 3 –Examine the wiring and expect for any signs of damage or wear that will indicate y'all need a replacement.
• Step iv –If there is no damage, then you reset your sensor by pressing the button on the sensor for up to 10 seconds.
• Stride 5 –The sensor may benefit from some cleaning to remove whatever dirt or grit that is impacting its ability to perform.
• Pace vi –And so reinstall the equipment past reattaching the clip and screwing the sensor back into place.
• Step 7 –Examine the reading against a reliable source (ie, real-time weather reports) to see if information technology is working correctly.
