Rough idle after check engine code cleared

I have a 99 SHO and have the engine code error P0113 Intake Air Temperture Circuit High Output I have replaced the IAT Sensor and the car still idles rough I didn't have any real problems until I erased the engine code error from the computer I was just trying to get rid of the check engine light and now I have the rough idle problem any suggestions would be greatly appreciated.

I would check for any vaccum leaks,
You can take a spray bottle of water and spray around the intake manifold with the car running at idle.
The idle will change and get worst if the intake is leaking.
The intake gaskets could be the failure. I know autozone can get into the computer and clear the codes for free.

good luck

Undefinedas replacement on civic 98 sensor p0113


Possible causes for this code are: - Faulty Intake Air Temperature (IAT) sensor
- Dirty air filter
- Intake Air Temperature (IAT) sensor harness is open or shorted
- Intake Air Temperature (IAT) sensor circuit poor electrical connection. this code sets when: - An excessively high voltage from the sensor is sent to ECM. Usual Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P0113 1998 Honda Civic Description The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.

What does p0113 mean on dodge durango 2002, and how to solve it?


Fault Code Definition
  • Intake Air Temperature Circuit High Input
What does this mean?
The Intake Air Temperature Sensor measures the rise and fall of the air temperature inside the Intake Manifold. This provides critical data needed for the Powertrain Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing and many components of the Emission Control Systems.
Code P0113 sets when the voltage signal to the PCM from the Intake Air Temperature Sensor Circuit stays above 4.5 volts while the Coolant Temperature Voltage readings are rising and falling within an appropriate range.
Symptoms
  • Check Engine Light will illuminate
  • In some cases, the engine may be hard starting and/or get poor fuel economy
  • Poor engine performance/hesitation on acceleration
Common Problems That Trigger the P0113 Code
  • Defective Intake Air Temperature Sensor
  • Dirty air filter
  • Defective Mass Air Flow Sensor
  • Faulty or corroded Intake Air Temperature Sensor wiring or connections
Common Misdiagnoses
  • Intake Air Temperature Sensor is replaced when the real cause is a dirty air filter
  • Intake Air Temperature Sensor is replaced when the real cause is a poor connection or chafed wiring
  • Intake Air Temperature Sensor is replaced when the real problem is in the Mass Air Flow Sensor
  • P0113 Diagnostic Theory for Shops and Technicians
  • When diagnosing a P0113 code, it is important to record the freeze frame information and then to duplicate the code setting conditions with a test drive while paying close attention to engine load, throttle position, RPM, and road speed on a data streaming scan tool. As you drive the vehicle, compare these values to the Intake Air Temperature Sensor PID or parameter ID. The Intake Air Temperature Sensor voltage values should rise and fall with changes in engine temperature. Compare the Intake Air Temperature or IAT readings to the Coolant Temperature Sensor readings, as they should move in tandem with each other. However, the Engine Coolant Temperature sensor will have a much higher temperature range.
    Check the IAT sensor connector with the key on and the engine off. There needs to be a steady 5 volt reference voltage and a very good ground. Find and use the proper engine performance wiring diagram to discern the proper color and position of these wires in the connector.
    It never hurts to do a key on-engine off voltage output test of the IAT sensor. Typically, I CAREFULLY use a heat gun to raise the temperature of the area around the sensor and study the change in values of the Intake Air Temperature. It's important to use the scan tool data stream as this will verify the IAT harness and connections.

P0113 code for the intake air temperature sensor


Thank you for the inquiry.
P0113
Intake Air Temperature Circuit High Input
P0114 Intake Air Temperature Circuit
P0113 - Intake Air Temperature Circuit High Input

The powertrain control module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.

Potential Symptoms: There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).
Causes: A code P0113 may mean that one or more of the following has happened:
* Internally failed IAT sensor
* Faulty connection at IAT sensor
* Open in IAT ground circuit or signal circuit
* Short to voltage in IAT signal circuit or reference circuit
* IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)
* Faulty PCM (less likely but not impossible)

Possible Solutions:
1. First, if you have access to a scan tool, is there an IAT reading? If the IAT reading is logical then the problem is likely intermittent. If the reading is less than -30 degrees, unplug the connector. Install a jumper wire between the harness connector signal and ground circuits. The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. 2. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground.
3. If now the IAT reading on the scan tool is maxed out then check for an open in the IAT ground circuit. If you get no reading at all on the scan tool, it's likely that the sensor signal is open or the 5 volt reference is missing. Check using a DVOM (digital volt ohm meter) for a 5 volt reference. If it's there, then unplug the connector at the PCM and check for continuity on the IAT signal circuit between the PCM connector and the IAT connector.

The car has 2 codes first p0113 then p1627


P0113 - Intake Air Temperature Sensor (IAT sensor) Circuit High Input. Possible causes - Dirty air filter
- Intake air temperature (IAT) sensor harness is open/disconnected or shorted
- Intake air temperature (IAT) sensor electrical circuit poor connection
- Faulty intake air temperature sensor. P1627 PCM/ECM A/D Conversion Error

This is a code indicating that the on-board computer could not convert a piece of data it was given by one or more sensors. This one must be taken in and read the freeze frame data to see under what condition it detected an error and tech has to chase this problem. they will want to put a PCM in it and reprogram. no good news for this problem except have the code cleared for now and hope it doesn't come back.
