What does the Check Engine code p0112 mean?

What does the Check Engine code p0112 mean?

“Check engine” light with diagnostic trouble codes P0112 or P0113 The engine computer module (ECM) may be able to deal with a faulty IAT sensor without much of a problem. However, some engines rely on the IAT sensor to turn on the cold-start injector or operate the EGR valve.

What causes an intake air temperature code p0113?

Most intake air temperature sensor problems for code P0113 are failures from damaged shorted harnesses or from sensors shorted internally to power. Need help with a P0113 code? YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.

What is the diagnostic trouble code for IAT sensor circuit?

P0112 is a diagnostic trouble code (DTC) for “IAT Sensor Circuit Low Input Problem”.

What is the error code for intake air temperature?

Error Code p0112 is defined as IAT (Intake Air Temperature) Sensor 1 Circuit Low.

What causes the OBD-II trouble code p0112?

P0112 is the OBD-II generic code that the engine control module (ECM) has recorded the IAT sensor input below the expected sensor range. What causes the P0112 code? If the output voltage is less than 0.18 V for 0.5 seconds or more, the ECM determines that there is a short in the sensor circuit, and sets trouble code P0112.

What causes a p0112 intake air temperature circuit?

Usually the P0112 is caused by a bad IAT (internally shorted or open or otherwise damaged), but it could also be: No reference voltage to the IAT sensor due to an open wire Excessively high intake air temperatures Short to ground on signal circuit

When does a PCM set a p0112 code?

If the PCM notices that the incoming air temp is unusually high, say, 300 degrees, when the engine temp is still relatively low, it will set a P0112 . There may be no noticeable symptoms of a P0112 code other than an MIL (Malfunction Indicator Lamp). However, a emissions test may reveal higher Nox readings depending on the type of IAT failure.

P0112 is a diagnostic trouble code (DTC) for “IAT Sensor Circuit Low Input Problem”.
