What is the P0114 fault number? What is the description for Intake Air Temperature Sensor Circuit Intermittent/Erratic Input Failure? How can you fix P0114 fault codes? What are the symptoms and causes for the P0114 fault code
What is the P0114 Fault code? What does it all mean?
The powertrain control module (PCM), if it detects an intermittent or irregular voltage signal from the intake temperature (IAT sensor circuit) for a specific period of time, will store a P0114 error code.
The IAT sensor monitors the temperature of the air entering into the intake manifold. The input signal from the sensor is used by PCM to calculate ignition timing strategy, fuel delivery and other components of the emission control systems.
The IAT sensor is typically located in the intake manifold. You can integrate it into the air intake pipe or air cleaner box, or in the mass air flow (MAF sensor body).
The IAT sensor usually has a two-wire thermistor. The sensor’s resistance will change depending on the temperature of the air passing through it. The resistance will be higher if the air is cold. If it is hot, it will be lower. Voltage fluctuations are caused by voltage fluctuations due to changes in the resistance. Based on these fluctuations, the PCM can determine the intake air temp. The PCM will log fault code “P0114” if the voltage signal for a particular number of sensors is lost for a given time.
The P0114 fault code can affect vehicles of all makes and models, including the Volkswagen Beetle, Pontiac Jeep, Mazda, Mercedes Benz Hyundai, Pontiac, Volkswagen, Pontiac, Jeep, Mazda, Pontiac, Pontiac, Jeep, Pontiac, Pontiac, Pontiac, Jeep, Mazda and Mercedes Benz.
What is the P0114 Fault Code?
There are many reasons to set the P0114 fault code. Fault codes are not specific indications of the problem. It indicates potential malfunctioning causes. It is important to diagnose the problem. These are the reasons why fault code P0114 should be set.
- – IAT sensor circuit – Open or closed
- – IAT sensor connectors are prone to corrosion or other problems.
- – Defective IAT sensor
- – Defective MAF sensor
- – A clogged air filter
- – Broken intake air inlet pipe
- – A PCM that is not working or requires a software upgrade
What are the symptoms for P0114 Malfunction Codes?
These symptoms may be present if you own a vehicle that has the code P0114.
- – Illumination for the check engine light
- – Increased fuel consumption
- – Low engine performance
- – Idle Speed Variations
- – Engine hesitation when acceleration is attempted and black smoke coming from the exhaust
- – Sometimes the engine may not start at all.
- – The engine might pre-ignite and run a little lean
- – The PCM may enter or exit fail-safe mode. This can cause the engine’s to run erratically.
- Other fault codes may also be activated
Note: Different symptoms may indicate malfunction depending on the manufacturer’s PCM programming strategy.
How do I fix the P0114 fault code?
- Road testing is necessary to determine if codes will be returned.
- – Repairing short and open circuits in the wiring harness for the IAT sensor
- – Repair of loose or corrosion on connectors
- – Clean and replace the clogged or dirty air filter
- Vacuum leak repair at intake air intake
- – Test and replacement of the IAT sensor
How serious is the P0114 Fault code?
If the code is P0114, the PCM will enter fail safe mode. The vehicle may behave strangely if it enters this mode. This can cause excessive carbon buildup and malfunctioning ignition systems.
