Mazda 6 Service Manual: Intake air temperature (iat) sensor inspection
Resistance Inspection
Note
- Perform the following inspection only when directed.
1. Disconnect MAF/IAT sensor.
2. Measure the resistance between the MAF/IAT sensor terminals D and E using an ohmmeter.
- If not as specified, replace the MAF/IAT sensor.
- If the MAF/IAT sensor is okay, but the IAT PID are out of specification, perform the Circuit Open/Short Inspection.
Specification
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION.)
2. Inspect the following wiring harnesses for open or short. (Continuity check)
Open circuit
- If there is no continuity, the circuit is open. Repair or replace the harness.
- MAF/IAT sensor terminal D (harness-side) and PCM terminal 2E (harness-side)
- MAF/IAT sensor terminal E (harness-side) and PCM terminal 2H (harness-side)
Short circuit
- If there is continuity, the circuit is shorted. Repair or replace the harness.
- MAF/IAT sensor terminal E (harness-side) and power supply
- MAF/IAT sensor terminal D (harness-side) and power supply
- MAF/IAT sensor terminal D (harness-side) and body GND
Pcm configuration
1. Connect the WDS to DLC-2.
2. Set up the WDS (including the vehicle recognition.)
3. Select Module programming.
4. Select Programmable module installation.
5. Select PCM and perform procedures ...

Mazda 6 Service Manual: Variable tumble control system (vtcs) shutter valve actuator inspection
1. Remove the air hose. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)
2. Disconnect the vacuum hose from the VTCS shutter valve actuator.
3. Connect a vacuum pump to the VTCS shutter valve actuator.
4. Apply vacuum and verify that the rod moves.
If the rod dose not move, replace the intake ...
Mazda 6 Service Manual: Manifold absolute pressure (map) sensor inspection
Note
Perform the following inspection only when directed.
The following vacuum values are indicated by relative pressure
from the MAP sensor.
1. Connect the SSTs (WDS or equivalent) to the DLC-2.
2. Turn the ignition switch to ON (Engine OFF).
3. Select MAP PID on the SSTs (WDS or equi ...
