I recently received a PO113 code on diagnostic Computer. I found out it is the Intake Temp Sensor and now I can't find the stinking thing. Can anyone help me locate it. This is a first for me as I am new to this.

Welcome to AF. Look in the ducting from the air box to the the throttle body. In the future post what engine also.

Thanks for the advice, It is a 2.2 4 cyl., 2wd auto. I will take a look tonight in the box again as I looked yesterday. I appreciate your help. Im not that mechanically knowledgeable so any help is great.

If you find out where it is let me know Please.

The Intake air Temp Sensor (IAT) is inside the air duct after the air filter housing, before the intake manifold. That code means there is high input to that sensor. If you have a digital multimeter, you can check it easily. Here's how.

It helps if you remove the air filter duct from your engine before starting this, so the sensor is easier to check, but it's not necessary. Disconnect the IAT sensor and with your ignition key on (engine not running), probe terminal A, the ground (black) and terminal B, REF (tan). Meter should read approx. 5.0 volts. Next, measure resistance across the terminals. By measuring its resistance when cold, then warming it up (a hair dryer can be used for this instead) and taking another measurement, you can see if the sensor is bad. The resistance of the sensor should be HIGH when the temp is low. Next, start the engine (with your sensor on the engine), let it idle. Wait awhile and let the engine reach normal operating temperature. Turn the ignition key OFF, disconnect the IAT sensor and check the resistance across the terminals. The resistance should be LOW when the air temperature is high. If the sensor does not exhibit this change in resistance, replace the sensor. You can also check your sensor with a SCAN tool. Install the SCAN tool and switch to the IAT mode and monitor the temperature with the engine cold and then completely warmed-up. The SCAN tool temp ranges should increase while the IAT sensor resistance decreases. If the IAT sensor temperature/resistance readings are incorrect, replace your sensor.

To replace the sensor, unplug the electrical connector and remove the sensor from the air intake duct. Twist the sensor to release it from the rubber boot.

If you check your sensor and the readings are correct, the problem lies in the wiring, and you will have to check the circuit for the IAT sensor to find the problem.
