- Repairing or replacing the wiring as necessary.
- Replacing the IAT with a new sensor.
What causes a P0112 code?
Error Code p0112 is defined as IAT (Intake Air Temperature) Sensor 1 Circuit Low. This means, there’s the PCM receives excessively low voltage from the IAT sensor, and usually caused by a failed IAT sensor or wiring issue.
Why is the Check Engine light on on my Volkswagen Passat?
Turn the engine on and check to make sure the check engine light is off. The Check Engine Light on your Volkswagen ( Jetta, Passat, Golf, Tiguan, etc.) can come on for many reasons, including defective mass airflow sensor, bad thermostat, engine temperature sensor, short in main wire harness, vacuum leak, worn spark plugs and failed ignition coils.
Where is the IAT sensor in the intake manifold?
It can be located on the air cleaner, in the air inlet tube, or in the intake manifold. The IAT sensor is a two-wire sensor with a negative temperature coefficient resistor positioned so that it reads the air entering the engine.
What does low input intake air temperature sensor mean?
Intake Air Temperature Sensor 1 Circuit Low Input What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
When to replace the IAT sensor on a PCM?
If you find none, unplug the IAT sensor and recheck the reading. It should now read the minimum, around -20 deg. If it does, then replace the IAT sensor. But, if the reading is still high, unplug the sensor and check for resistance across the two wiring harness terminals. If there is infinite resistance, then the PCM itself is bad.
