Manifold Absolute Pressure - Mazda CX-7 2007 Workshop Manual

MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/BOOST AIR TEMPERATURE SENSOR REMOVAL/
INSTALLATION[L3 WITH TC]
1. Disconnect the negative battery cable.
2. Remove the charge air cooler duct. (See01-13-5 INTAKE AIR SYSTEM REMOVAL/INSTALLATION[L3 WITH
TC].)
3. Remove the oil level gauge pipe. (See01-11-6 OIL PAN REMOVAL/INSTALLATION[L3 WITH TC].)
4. Disconnect the MAP/boost air temperature sensor connector.
5. Remove MAP/boost air temperature sensor from
the intake manifold.
6. Install in the reverse order of removal.

MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION[L3 WITH TC]
Note
• Perform the following inspection only when directed.
• The following vacuum values are indicated by relative pressure from the MAP sensor.
1. Connect the M-MDS to the DLC-2.
2. Turn the ignition switch to ON (Engine off).
3. Select MAP PID on the M-MDS.
4. Verify that the MAP PID (pressure) and
barometric pressure are practically equal.
• If not as verified, perform the "Circuit Open/
Short Inspection".
— If there is no open or short circuit, replace
the MAP sensor.
• If as verified, go to next step.
5. Apply vacuum of –25.0 kPa {–187 mmHg, –7.38
inHg} to the MAP sensor, and verify that the MAP
variation from that of Step 4 is approx. 25.0 kPa
{187 mmHg, 7.38 inHg}.
• If not as verified, perform the "Circuit Open/Short inspection".
— If there is no open or short circuit, replace the barometric pressure sensor. (See01-13-5 INTAKE AIR
SYSTEM REMOVAL/INSTALLATION[L3 WITH TC].)
