Error Code P0114: What It Means & What To Do?

<<See All OBD Codes

The P0114 error code can be defined as intake air temperature circuit intermittent. It is a generic error code which would indicate that the powertrain control module has recorded an intermittent or erratic voltage signal from the IAT. This trouble code is related to P0111, P0112 and P0113 fault codes.

Want to learn more about P0114 fault code? An IAT sensor is built into the mass airflow sensor for few vehicles and it is mounted to air filter duct housing. It is this sensor which would detect the intake air temperature and that information would then be transmitted to the powertrain control module. It comes with a thermistor, which is a device sensitive to the changes in the temperature. This data is used by the powertrain control module to control a lot of aspects of the engine emission control system which would include the fuel ratio as well as ignition spark timing.

 What causes this problem with the Intake Air Temperature Circuit Intermittent?

• There can be some faults in the intake air temperature sensor
• The air filter might be dirty
• The intake air temperature sensor harness might be opened or shorted
• There can be bad electrical connection in the intake air temperature sensor circuit

1. Intake Air Temperature Sensor - Intake Air Temperature Sensor is an important car part which should never be neglected. May be there is some fault in it due to which P0114 code may start flashing.
2. Air Filter - Is your Air Filter damaged or broken? Don’t worry as we have solutions for all your problems.
3. Engine Control Module - Defective car Engine Control Module can be a major reason why P0114 code depicts. So, make sure to replace it online so that you don’t have to face any further issues.
4. Powertrain Control Module - Everything is okay with the timing chain and still OBD code P0114 triggering? Then there must be some defects in Powertrain Control Module. Replace them as soon as possible.
5. Intake Manifold - P0114 code flashing? Get your Intake Manifold inspected from a mechanic.
6. Wiring - Take care of car Wiring or else can it trigger the P0114 code. You can rely on us to purchase best quality Wiring online.
7. Engine Sensor - There can be some defects in the Engine Sensor due to which P0114 code may come on again and again. Make sure to replace it or else you may have to face some major issues.
8. Connector - There can be some issues with the Connector due to which you may see P0114 code appearing over and over again. Visit us to buy best quality Connector online.

Willing to know some common symptoms of OBD Code P0114? Your wish is our demand. Have a look at them below:

Common Symptoms

• The ECM can start turning on the check engine light and it would go into a failsafe mode
• There can be the issue of intermittent hard starting
• The overall fuel mileage can start varying from good to bad depending on sensor values
• Exhaust can start emitting black smoke out of the tailpipe on acceleration
• Engine may have pre-ignition and can start running lean

• You must repair or replace the IAT connector to fix shorts or the open circuit that are caused by corrosion
• The wiring should be repaired or replaced if necessary, to fix shorted or open circuits in the harness
• The IAT sensor should be replaced with a new sensor

Facing such issues? All you have to do is to visit us as we have stocked a wide range of best priced replacement parts, battery connectors , ecm system parts and a lot more to help you out in fixing your car.

• Scan the engine control module, the codes received should be documented, and the freeze frame data should be viewed to see the conditions present when the code was set
• The next important step is to clear the vehicle of fault codes and the retests the vehicle to see if the code comes back
• You must perform a visual inspection to see if there is a disconnected or loose electrical connector to sensor
• You can always look at harness and connector for a short to power
• The sensor’s live data on the scanner should be carefully observed while doing a wiggle test for an open or short circuit in the wiring, connections or sensor
• The mechanic should perform the manufacturer's specific pinpoint tests for the code and repair as per the requirement

Common Mistakes When Diagnosing The P0114 Code

• Not performing a visual inspection of connections and wiring can be a big mistake
• You must follow the manufacturer pinpoint test procedure step-by-step and should not skip any steps
• You should replace an IAT sensor only when tests indicate a problem
• Make sure that you connect a new or known good sensor to the harness and viewing the ECM data to see if the temperature output from the sensor is as expected
