4. INSPECT AIR FILTER
(a) Visually check that the air cleaner element is not exces-
sively dirty, damaged or oily.
HINT:
Oiliness may indicate a stuck PCV valve.
If necessary, replace the air cleaner element.
(b) Clean the element with compressed air.
First blow from back side thoroughly, then blow off the
front side of the element.
5. REPLACE AIR FILTER
Replace the used air cleaner element with a new one.

DTC P0110 Intake Air Temp. Circuit Malfunction
CIRCUIT DESCRIPTION
The intake air temp. sensor is built into the air cleaner cap and
sensors the intake air temp.
A thermistor built in the sensor changes the resistance value
according to the intake air temp. The lower the intake air temp.,
the greater the thermistor resistance value, and the higher the
intake air temp., the lower the thermistor resistance value (See
fig.1).
The intake air temp. sensor is connected to the ECM (See be-
low). The 5 V 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 con-
nected in series. When the resistance value of the intake air
temp. sensor changes in accordance with changes in the intake
air temp., the potential at terminal THA also changes. Based on
this signal, the ECM increases the fuel injection volume to im-
prove driveability during cold engine operation.
If the ECM detects the DTC ”P0110”, it operates the fail safe
function in which the intake air temp. is assumed to be 20°C
(68°F).
