Where is the IAT sensor located?

The intake air temperature sensor (IAT) is located at the bottom of the intake collector, directly behind the acceleration valve box.

How do you diagnose a bad IAT sensor?


  1. Fault code is stored, engine indicator lamp may come on.
  2. Problems starting.
  3. Reduced engine power.
  4. Increased fuel consumption.

Will a bad IAT sensor throw a code?

Common Causes of the P0113 Code – A faulty or damaged IAT sensor. This is a very common cause. – Damaged wiring. Short circuits or stripped wires can cause all kinds of things to go wrong with your electrical systems.

Can you bypass intake air temperature sensor?

Intake Air Temp Override. It’s a little known racing tip that you can unplug your IAT sensor and you will trick the onboard computer into thinking that it’s 32 degrees out (creating a rich fuel mixture). So the resistor acts as a jumper and returns a 3.3Kohm load to the ECM (bypassing the sensor itself).

Can I drive with a bad IAT sensor?

All a IAT sensor is, is a thernistor that changes resistance based on temp. Though your engine will run “okay” it will not run as well as it should, without the IAT Sensor. The ECU simply cannot process all needed information properly.

What are the symptoms of a bad air temperature sensor?

Symptoms of a Bad or Failing Air Charge Temperature Sensor

  • Lack of power when accelerating. One of the first symptoms that a vehicle will display when the air charge temperature sensor has failed is a noticeable reduction in power when accelerating.
  • Trouble with cold starts.
  • Decrease in fuel efficiency.

Can you clean a IAT sensor?

The air temperature sensor is a solid state component. If the sensor is dirty, you can clean it to make it work again. Use an electronic cleaner to clean the sensor after removing it from the intake manifolds.

What is the IAT sensor on a Ford Ranger?

The IAT sensor is responsible for measuring the air temperature and density to achieve the optimal air/fuel mixture for any condition. P0113 is specifically thrown when the Ranger’s computer sees a voltage signal of 4.91 volts for over half a second at the Intake Air Temp Sensor.

What is an OBDII problem code on a Ford Ranger?

P0113 is an OBDII trouble code that occurs when the Ford Ranger’s engine management computer detects that there is an issue with the Intake Air Temperature (IAT) Sensor, specifically that there is a High Input Problem with it.

Is there a problem with Ford Ranger p0113?

There can be symptoms associated with P0113. Depending on the time of year, IAT sensor issues can be a real problem. When it is cold outside, it may be more difficult for your Ranger’s engine to start. This is due to a lean condition that’s more noticeable when the air temperature is lower.

What does the IAT sensor 4.0L do?

The IAT sensor (4.0L): – sends the PCM a signal indicating the temperature of the air entering the engine. – resistance decreases as temperature increases. – has the ability to create a voltage signal dependent on exhaust oxygen content.
