What is the P0113 fault number? What is the description for the Intake Air Temperature Sensor Circuit High Input Problem Bank 1 malfunction? How do I fix P0113 fault code What are the symptoms and causes of the P0113 error code?
What is the P0113 fault code?
P0113 is a general fault code. It is triggered when the Intake Air Temperature Sensor, (IAT) signal range of the Engine Control Module (ECM/PCM/ECU) is outputting more than expected. This code is set by the engine computer to indicate a problem in the IAT sensor 1.
The IAT sensor monitors the intake manifold’s temperature. The sensor sends the data to the ECM. This data is used by the ECM to tune the fuel injectors and air/fuel mixture, EGR va, and other components controlling the combustion chamber. This data helps the engine burn fuel more efficiently.
The ECM will generate a P0113 code if it detects a signal voltage higher than its maximum value. In other words, if the output voltage of the sensor is higher than 4.91 V for more than 0.5 seconds, the ECM will set a malfunction code P0113. The ECM is aware that the intake manifold temperature won’t exceed -40 degrees, but this information is false.
The intake temperature sensor (IAT), is not available for all engines. Fault code P0113 does not apply to all vehicles. Some vehicles have a Mass Air Flow Sensor, (MAF). The ECM needs to know how the air temperature was measured. For a good air/fuel mixture, it is important to account for the fact that cold air contains more oxygen molecules per cubic centimeter than warm air.
IAT is a thermometer that alters resistance according to temperature. The resistance decreases with increasing temperature. The voltage to the ECM can peak if the sensor is removed. This is equivalent to -40°C.
Other IAT sensor fault codes and circuit-related fault codes: P0095/P0096/P0097/P0098/P0099/P0099/P0110,P0111,P0112,P0114,P0127
What Are the Signs of P0113 Fault Coding?
- – The engine light will come on when you turn the key. Sometimes, there might not be any other symptoms.
- – Too much or too little air/fuel mixture
- – Engine is not starting or running smoothly
- Problems with ignition
- – Reduced engine power/regret in acceleration
- – High fuel consumption
- – High Emission Values
- – Exhaust fuel smell
What causes the P0113 Fault code?
- – Dirty filter
- – IAT sensor that is dirty or defective
- – Bad IAT circuit wiring and connectors.
- – Problems with mass air flow sensor (MAF), if the IAT sensor has been integrated into the MAF sensor.
- ECM related issues
What is the importance of the P0113 Fault Code
An ECM code of P0113 will put it in safety mode. Depending on the manufacturer’s engine strategy, an engine failsafe mode can cause problems with engine performance. The failure of engine components may occur if the vehicle is operated in this way for a prolonged period.
