As the atmospheric pressure described on the synoptic chart is the value at sea level, compensate the

pressure with the following chart.

6. Check the manifold absolute pressure sensor value corresponding to the atmospheric pressure.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace MAP sensor.

2.

CHECK MAP SENSOR-II

1. Start engine and let it idle.

2. Check intake manifold vacuum.

3. Check the voltage between ECM harness connector terminals as follows.

4. Confirm the difference of the voltage when engine is stopped and at idling is within the values shown in

the following chart.

Is the inspection result normal?

YES

>> INSPECTION END

NO

DTC CONFIRMATION PROCEDURE

1.

INSPECTION START

Is it necessary to erase permanent DTC?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to 

EC-855, "Component Function Check"

.

NOTE:

Use the component function check to check the overall function of the IAT sensor circuit. During this check, a

1st trip DTC might not be confirmed.
Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Proceed to 

EC-855, "Diagnosis Procedure"

.

3.

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

• Before performing the following procedure, do not add fuel.

• Before performing the following procedure, check that fuel level is between 1/4 and 4/4.

• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 4.

4.

PERFORM DTC CONFIRMATION PROCEDURE

1. Move the vehicle to a cool place.

NOTE:

Cool the vehicle in an environment of ambient air temperature between 

−10°C (14°F) and 35°C (95°F).

2. Turn ignition switch OFF and leave the vehicle for 12 hours.

CAUTION:

Never turn ignition switch ON during this procedure.

NOTE:

The vehicle must be cooled with the hood open.

3. Start engine and let it idle for 5 minutes or more.

CAUTION:

Never turn ignition switch OFF during idling.

4. Check 1st trip DTC.

DTC No.

IAT SENSOR 1 B1
(Intake air temperature sensor 1 
circuit range/performance)

The comparison result of signals transmitted 
to ECM from each temperature sensor (IAT 
sensor, ECT sensor, FTT sensor, and EOT 
sensor) shows that the voltage signal of the 
IAT sensor is higher/lower than that of other 
temperature sensors when the engine is 
started with its cold state.

• Harness or connectors

(High or low resistance in the IAT 
sensor 1 circuit)

• IAT sensor 1
