Code P0110 2001 Toyota Echo Description
resistance value. The air intake temperature sensor is connected to the ECM. The 5V power source voltage in the ECM is applied to the intake air temp. sensor from the terminal THA via a resistor R. That is, the resistor R and the intake air temp. sensor are connected in series. When the resistance value of the intake air temp. sensor changes in accordance with changes in the intake air temperature, the potential at terminal THA also changes. Based on this signal, the ECM increases the fuel injection volume to improve driveability during cold engine operation.
What are the Possible Causes of the DTC P0110 2001 Toyota Echo?
- Faulty Intake Air Temperature (IAT) sensor
- Dirty air filter
- Intake Air Temperature (IAT) sensor harness is open or shorted
- Intake Air Temperature (IAT) sensor circuit poor electrical connection
