What is code P0072?

Ambient Air Temperature Sensor Circuit Low

OBD-II Code P0072 is defined as a Ambient Air Temperature Sensor Circuit Low. The ambient temperature sensor helps the engine control module (PCM) determine how much fuel to use on startup. The PCM also uses this signal as a logic reference for other temperature sensors on the engine.

Where is the outside temperature sensor on a car?

Generally, the outside temperature sensor is located under the front of the hood near the bottom of the car. Although the sensor itself is accurate, the location causes the sensor to pick up heat from the road surface. Thus, it will usually read several degrees higher than the air temperature.

What causes a P0172 code?

What the P0172 code means. P0172 indicates that there is too much gasoline being detected in the exhaust gases exiting the combustion chamber. The ECU uses a number of instruments, such as the mass air flow sensor (MAF), oxygen sensors, and manifold absolute pressure (MAP) to monitor the air-fuel ratio of the engine.

Why is my car reading the wrong outside temperature?

The sensor that measures outside temperature is typically up behind the bumper, which is near the hot asphalt and the engine. That’s why it reads a little higher that what the temperature actually is outside. Even if it’s a little off, you should always be monitoring that gauge.

How many temperature sensors are in a car?
