Repair Importance Level: 3/3
Repair Difficulty Level: 2/3  What does this mean?

P0110 2000 TOYOTA ECHO Possible Causes

  • 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

Cost of diagnosing the P0110 2000 TOYOTA ECHO code

    Labor: 1.0

    The cost of diagnosing the P0110 2000 TOYOTA ECHO code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

When is the P0110 2000 TOYOTA ECHO code detected?

An excessively low or high voltage from the sensor is sent to ECM.

P0110 2000 TOYOTA ECHO Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)

P0110 2000 TOYOTA ECHO Meaning

The intake air temp. sensor is built into the mass air flow meter and senses the intake air temperature. A thermistor built in the sensor changes the resistance value according to the intake air temperature, the lower the intake air temperature, the greater the thermistor resistance value, and the higher the intake air temperature, the lower the thermistor

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.
