Fault code P0110 is logged when the engine control module (ECM) has detected an issue with the intake air temperature (IAT) circuit. This is a general malfunction code for the circuit in question.
The IAT sensor is responsible for relaying information about the IAT to the ECM. this is done to allow for adjustments to the air-fuel mixture for optimization.
A properly functioning IAT provides valuable information to the ECM regarding the incoming air temperature. This allows the ECM to adjust the air-fuel mixture accordingly to allow for optimal efficiency and operation.
This code is specific to the bank 1 air intake sensor.
Other Signs of This Problem
It is possible for this fault code to come with other signs of the issue. However, it is also possible for no symptoms to arise.
One of the most obvious signs will be the presence of the Check Engine light on the dashboard.
Other signs include the engine running poorly. This is because the ECM cannot optimize the air-fuel mixture well without the proper readings from the IAT sensor.
It is likely that fuel economy will also be reduced.
What Could Be The Problem?
The majority of the causes for this error are those commonly found in the IAT circuit. These encompass all parts like the circuitry, wiring, and electrical components like sensors.
The most obvious cause of P0110 would be an issue with the bank 1 IAT sensor itself. If the sensor or its connections are faulty, they can provide inaccurate readings.
A faulty mass airflow (MAF) sensor could also be the cause of this issue. The same can be said of a dirty MAF sensor.
Damaged wiring and loose connections can also cause this malfunction.
If the electrical components are not at fault, it could be an issue with the PCM or its software. However, this will likely come with various additional fault codes being logged.
The fixes for this issue will mostly be done within the IAT sensor circuit itself. They will typically be electrical in nature.
Ensure the IAT sensor is operating correctly. If there is an issue with the sensor specifically, it should be replaced.
Check that there are no damaged wires or connections between the IAT sensor and its circuit.
Also, ensure that there is no dirt or rust that could cause these issues. These connections must also be attached securely.
If the IAT sensor is linked to the (MAF) sensor, there could be an issue with the MAF sensor or its wiring that could cause this reading.
Fault code P0110 can be considered moderately serious. Extended operation of the vehicle can cause damage to the engine.
Another factor that increases the severity of this issue is the potential for a no-start on an unexpectedly cold morning.
It is a good idea to have this fault code fixed as soon as possible.
