Problems with the Intake Air Temperature Sensor ...

· Just looking up the generic codes relating to Intake Air Temp., I see there are 6 of them. Namely, P0110 -P0114 and P0127 They all relate to the IAT circuit in general - not necessarily the sensor itself. If whatever in the circuit interprets the Ohm reading of the sensor under varying temperature is not doing it correctly,

Simple Ways to Test a Temperature Sensor with a Multimeter

· With your temperature sensor still attached to the multimeter, press the power button to activate it. Locate the DC setting on the dial of the sensor and turn the dial to select it, or select the DC setting if your multimeter doesn’t have a manual dial. The DC setting will give you a voltage reading that you can use to test your sensor. 4

Part 5 -How to Test the Intake Air Temp (IAT) Sensor (GM )

· CASE 1: The multimeter recorded to 5 Volts DC-So far so good, since this test result tells you that two very important things: That the PCM is supplying 5 Volts on wire D.; That the PCM is supplying a Ground on wire E.; NOTE: If you're coming from TEST 7 or TEST 8, then this result tells you that the most likely cause of the DTC P0113 (Intake Air Temperature (IAT) Sensor Circuit High ...

Intake air temperature sensor —What is an intake air ...

· You can test an intake air temperature sensor using a digital Ohm Meter set on the DC volts scale. Turn the IGN switch to the ON position and backprobe the return wire to see the voltage being reported to the PCM/ECM. You can also test the sensor’s resistance, but that’s not as accurate as reading the actual return voltage. How to replace an intake air temperature sensor? Intake air ...

How to Test a Coolant Temperature Sensor |

· Testing the coolant temperature sensor is a very quick process. With the use of a digital volt-ohm meter you can easily tell if the sensor is faulty or not. Connect the black lead of the digital ohm meter to a solid grounding. This can be any solid piece of metal. Next, remove the wire from sensor terminal and connect the red lead to the terminal end of the coolant temperature sensor. Before ...

How to Test a Temperature Sending Unit | It Still Runs

How to Test a Temperature Sending Unit by Lowell . Polka Dot Images/Polka Dot/Getty Images. The temperature sending unit, more properly known as a temperature sensor, is one of the most important sensors in your car. It is the sensor that tells the computer when the engine has warmed up sufficiently for the computer to pay attention to the many other sensors on the engine and exhaust. A ...

Testing Motorbike Coolant and Air Temperature Sensors

Should there appear to be a fault whilst testing at the ECM, the next course of action is to locate either sensor using manufacturer's data. Naturally the coolant temperature sensor is mounted on the engine and the intake air temperature sensor somewhere in the induction system. As this may involve removing the motorcycle's fairings, all tests are initially performed at the ECM.

· Also, if you test the NTC thermistor (both air and oil temperature are measured using NTC thermistors) with an ohm meter, remember, you are imposing a current across the device which will self heat the sensor and render an inaccurate reading of R vs T. You'll need a VOM with very high ohms to volts performance so as to limit self heat. #7
