Where is the intake air temperature sensor located on the Ford Transit?
1 Answers
The intake air temperature sensor is typically located on the intake hose after the air filter or on the mass air flow sensor. Here is a related introduction about the intake air temperature sensor: 1. Function: As a negative temperature coefficient thermistor, the intake air temperature sensor can detect the temperature of the intake airflow. When the intake temperature rises, the resistance value decreases, and when the intake temperature drops, the resistance value increases. The change in resistance in the intake air temperature sensor circuit causes voltage fluctuations, generating a different voltage signal. The ECU uses this voltage signal to calculate the actual temperature of the intake airflow and adjusts the engine's fuel injection and ignition accordingly. 2. Fault Analysis: If the ground wire of the intake air temperature sensor has poor contact, the data stream will display abnormally low temperatures. Low-temperature air has a higher density, which increases the fuel injection pulse width, resulting in an overly rich air-fuel mixture. If the sensor is short-circuited, the data stream will display abnormally high temperatures. High-temperature air has a lower density, which reduces the fuel injection pulse width, resulting in an overly lean air-fuel mixture. The higher the temperature detected by the intake air temperature sensor, the richer the air-fuel mixture. A broken or poorly grounded sensor can cause an overly lean mixture, leading to difficulty starting the engine.
