How do you figure out what is wrong when you get a P0113 and a P0401 codes?

Diagnostic trouble code P0113 stands for “Intake Air Temperature (IAT) Sensor Circuit High Input.” If your OBD-II scanner reports this code, it means your car's computer has determined that there's a problem with the IAT sensor 1 or its circuit. A working IAT sensor sends its readings to the PCM.

How do I fix error code P0113?

How to Fix It. Because a P0113 code is most frequently caused by either a dysfunctional circuit or a failed IAT sensor, the most common repair is simply replacing the faulty component. You can also try cleaning the IAT sensor tip and replacing the grounds.

Can a dirty air filter cause a P0113 code?

A faulty IAT sensor is the most common cause of a P0113 code. Dirty Air Filter: A dirty air filter is the second most common cause of error code P0113. If your air filter is dirty enough to hinder airflow, your air intake system has to work harder or may receive inadequate airflow.

What causes P0113?

Common Causes of the P0113 Code

– A faulty or damaged IAT sensor. This is a very common cause. ... – A defective mass air flow sensor. This is less common, but it can cause your car to try to draw too much air, which can be the root cause of an overheated air intake.

What will a bad air temp sensor do?

Rough idling and rough running

Engine stalling, rough idling, engine stumbling, and random surges of power are commonly associated with IAT sensor failure. These are concerning symptoms, and they can only worsen with time.

What is the code P0102?

What Does P0102 Mean? The Mass Airflow (MAF) sensor measures the amount of air entering the engine. When code P0102 is set, there is a low voltage output to the ECM, PCM, or ECU depending on your car type (check your owner's manual for your specific car).

What causes code P0138?

When trouble code P0138 is set, this indicates that there is a high voltage (steadily above . 9 volts) for more than 10 seconds indicating a lack of oxygen in the exhaust stream and an abundance of fuel at sensor 2 on the bank 1 of the engine.

Can P0113 cause no start?

The P0113 code is unrelated to your no start. Hi intake temp code is often the wires on the IAT (intake air temperature)sensor located on the intake snorkel are broken off, inside the plug. That's the good news the bad news is your car will still run well without it, even connected.

What is code P0118?

Code P0118 is the result of the ECT sensor indicating a high voltage input from the coolant temperature circuit. ( typically over 4.7V)

What is MAF sensor?

The mass air flow (MAF) sensor, part of your vehicle's electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. ... This causes the engine computer to miscalculate the amount of injected fuel, causing additional damage to your engine.

How is P0128 diagnosed?

The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose.

What does circuit high mean?

The Engine Coolant Temperature Circuit - High Input malfunction is the code for the onboard diagnostic (OBD). ... When the coolant temperature is low, the resistance of the sensor will be high, and when it is high, the resistance will be low.
