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

Why is my 2004 Ford Freestar 4.2 running so rough?

The code P2196 indicates that there is too much fuel in relation to the oxygen in your vehicle, or that the oxygen sensor is faulty and reading an incorrect air/fuel ratio, thats your engine is running rough.
Engine code P0113 could be caused by a number of things, including a bad sensor or faulty wiring.
This trouble code points to the oxygen sensor, it's natural to want to replace it and move on. However, you must first inspect the wiring and the sensor to ensure.

I am having a code P0113 and the car is using up too much gas

P0113 is an Intake Air Temp High Input error. High input in this cause, means the voltage sent to the PCM from the sensor is too high. This makes sense since the higher the voltage the PCM seem the lower the intake temperature seems to be to the PCM. Colder temperatures will cause the PCM to increase the fuel to the engine (like the old style choke/fast idle). You need to check the wiring to the Intake Air Temp Sensor, and if it is OK, replace the sensor.

Code P0113-P0183

DTC 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.


DTC P0183 - Fuel Temperature Sensor Circuit High Voltage.


I suggest to check wire connections.

P0206 p0113 p0123

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.

There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).

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)


P0123 Code - Throttle Position Sensor/Switch A Circuit High Input
A P0123 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too high a voltage. Some symptoms may include:
Rough idle
High idle
Surging
other symptoms may also be present

A code P0123 may mean that one or more of the following has happened:
TPS not mounted securely
TPS circuit short to ground or another wire
Faulty TPS
Damaged computer (PCM)


P0206 - Cylinder 6 Injector Circuit Malfunction
This means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.

The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.

The causes of a P0206 engine light code could be any of the following:
Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
Open in the wiring to the injector
Short in the wiring to the injector
Bad PCM

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.
