Honda Element. Manual — part 5

The IAT sensor output voltage is 0.08 V or less for at least 2 seconds.

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the
ECM/PCM memory.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by
disconnecting the battery.

DTC P0113: INTAKE AIR TEMPERATURE (IAT) SENSOR CIRCUIT HIGH VOLTAGE

Fig. 16: Intake Air Temperature (IAT) Sensor Output Voltage - Graph

General Description

The intake air temperature (IAT) sensor is a thermistor that detects intake air temperature, and it is used for A/F
feedback control to compensate for the atmospheric density fluctuations that accompany changes in intake air
temperature.

The IAT sensor resistance varies depending on temperature. The output voltage and the sensor resistance
increase as the intake air temperature decreases. Conversely, the output voltage and the sensor resistance
decrease as the intake air temperature increases. If the IAT sensor output voltage is excessively high, the engine
control module (ECM)/powertrain control module (PCM) detects a malfunction and a DTC is stored.

DTC P0116 (86): ADVANCED DIAGNOSTICS

DTC P0116: ENGINE COOLANT TEMPERATURE (ECT) SENSOR 1 CIRCUIT
RANGE/PERFORMANCE PROBLEM

Fig. 17: Engine Coolant Temperature (ECT) Sensor 1 Circuit Range/ Performance - Graph

2007 Honda Element EX

2007 ENGINE PERFORMANCE Advanced Diagnostics - Element

General Description

The engine control module (ECM)/powertrain control module (PCM) supplies voltage to the engine coolant
temperature (ECT) signal circuit (about 5 V) through a pull-up resistor. As the engine coolant cools, ECT
sensor 1 resistance increases, and the ECM/PCM detects a high signal voltage. As the engine coolant warms,
ECT sensor 1 resistance decreases, and the ECM/PCM detects a low signal voltage.

If the ECT sensor 1 output voltage after driving a set time after starting the engine does not reach a set
temperature, or when the difference between the ECT sensor 1 output voltage when driving and the output
voltage of the ECT sensor 1 after the engine is stopped a set time does not change a certain amount, a
malfunction is detected and a DTC is stored.

With a completely cooled engine (one that has been off for at least 6 hours): Judgment is
made after the engine has been run for at least 10 minutes, turned off for at least 10
seconds, then started and run again for at least 10 seconds.
With a partially cooled engine (one that has been off for less than 6 hours): Judgment is
made after the engine has been run for at least 10 minutes, turned off for at least 150
minutes, then started and run again for at least 10 seconds.
