GENERAL

Intake Air Temperature Sensor

The ECM supplies and monitors a signal at Pin 10 of [11] to
one side of the intake air temperature sensor (IAT sensor).
The other side of the IAT sensor is connected to a common
sensor ground, which is also connected to the ECM (Pin 7 of
[11]).

See

Table 4-45.

The IAT sensor is a thermistor device, mean-

ing that at a specific temperature, it will have a specific resis-
tance across its terminals. As this resistance varies, so does
the supplied voltage (Pin 10).

●

At high temperatures, the resistance of the sensor is very
low. This effectively lowers the signal voltage on Pin 10.

●

At low temperatures, the resistance is very high, allowing
the voltage to rise close to the supplied voltage of 5 volts.

The ECM monitors this voltage to compensate for various
operating conditions.

DIAGNOSTICS

Diagnostic Tips

An intermittent may be caused by a poor connection, rubbed
through wire insulation or a wire broken inside the insulation.

Check for the following conditions:

●

Poor connection.

Inspect ECM harness connector for

backed out terminals, improper mating, broken locks
improperly formed or damaged terminals, poor terminal-
to-wire connection and damaged harness.

●

Perform

4.7 WIGGLE TEST

to locate intermittents.

If

connections and harness check out OK, check intake air
temperature reading while moving related connectors
and wiring harness. If the failure is induced, the IAT sen-
sor display will change.

●

Shifted sensor.

The temperature-to-resistance values

table may be used to test the IAT sensor at various tem-
perature levels in order to evaluate the possibility of a
shifted (out-of-calibration) sensor which may result in
driveability problems.

Diagnostic Notes

The reference numbers below correlate with the circled num-
bers on the Code 15 flow charts.

1.

Connect BREAKOUT BOX (Part No. HD-42682) to EFI
harness

only

(leave ECM disconnected). See

4.6 BREA-

KOUT BOX.

2.

Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404), gray socket probes and patch cord.

3.

Use HARNESS CONNECTOR TEST KIT (Part No. HD-
41404), gray pin probe and patch cord.

NOTE

All voltage and resistance values are approximate (+/- 20%).
Intake air temperature sensor is measured between Terminal
10 of [11] and system ground (Terminals 2 and 11 of [10]).
